Original introduction below

Weighted maximum matching in general graphs.

The algorithm is taken from "Efficient Algorithms for Finding Maximum +Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. +It is based on the "blossom" method for finding augmenting paths and +the "primal-dual" method for finding a matching of maximum weight, both +due to Jack Edmonds. +Some ideas came from "Implementation of algorithms for maximum matching +on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

A C program for maximum weight matching by Ed Rothberg was used extensively +to validate this new code.

var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

If assigned, DEBUG(str) is called with lots of debug messages.

var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

Check delta2/delta3 computation after every substage; +only works on integer weights, slows down the algorithm to O(n^4).

if (CHECK_DELTA === undefined) CHECK_DELTA = false;

Check optimality of solution before returning; only works on integer weights.

if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

Compatibility

var assert = function (condition) { + if (!condition) throw new Error('Assertion failed'); + }; + + var min = function (a, i, j) { + + var o = a[i]; + + while (--j > i) { + if (a[j] < o) o = a[j]; + } + + return o; + }; + + var zip = function (a, fn) { + var shortest = a[0].length < a[1].length ? a[0] : a[1]; + + shortest.map(function (_, i) { + if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; + }); + };
var maxWeightMatching = function (edges, maxcardinality) { + var i, j, k, p, w, len; + + if (maxcardinality === undefined) maxcardinality = false;

Compute a maximum-weighted matching in the general undirected +weighted graph given by "edges". If "maxcardinality" is true, +only maximum-cardinality matchings are considered as solutions.

+

Edges is a sequence of tuples (i, j, wt) describing an undirected +edge between vertex i and vertex j with weight wt. There is at most +one edge between any two vertices; no vertex has an edge to itthis. +Vertices are identified by consecutive, non-negative integers.

+

Return a list "mate", such that mate[i] === j if vertex i is +matched to vertex j, and mate[i] === -1 if vertex i is not matched.

+

This function takes time O(n ** 3){

Vertices are numbered 0 .. (nvertex-1). +Non-trivial blossoms are numbered nvertex .. (2nvertex-1) +Edges are numbered 0 .. (nedge-1). +Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints +(2k) and (2k+1) both belong to edge k. +Many terms used in the comments (sub-blossom, T-vertex) come from +the paper by Galil; read the paper before reading this code.

Deal swiftly with empty graphs.

if (!edges.length) return [];

Count vertices + find the maximum edge weight.

var nedge = edges.length; + var nvertex = 0; + var maxweight = 0; + + len = nedge; + while (len--) { + i = edges[len][0]; + j = edges[len][1]; + w = edges[len][2]; + + assert(i >= 0 && j >= 0 && i !== j); + if (i >= nvertex) nvertex = i + 1; + if (j >= nvertex) nvertex = j + 1; + + maxweight = Math.max(maxweight, w); + }

If p is an edge endpoint, +endpoint[p] is the vertex to which endpoint p is attached. +Not modified by the algorithm.

p = 2 * nedge; + var endpoint = new Array(p); + while (p--) endpoint[p] = edges[Math.floor(p / 2)][p % 2];

If v is a vertex, +neighbend[v] is the list of remote endpoints of the edges attached to v. +Not modified by the algorithm.

i = nvertex; + var neighbend = new Array(i); + while (i--) neighbend[i] = []; + + for (k = 0; k < nedge; ++k) { + i = edges[k][0]; + j = edges[k][1]; + neighbend[i].push(2 * k + 1); + neighbend[j].push(2 * k); + }

If v is a vertex, +mate[v] is the remote endpoint of its matched edge, or -1 if it is single +(i.e. endpoint[mate[v]] is v's partner vertex). +Initially all vertices are single; updated during augmentation.

i = nvertex; + var mate = new Array(i); + while (i--) mate[i] = -1;

If b is a top-level blossom, +label[b] is 0 if b is unlabeled (free); + 1 if b is an S-vertex/blossom; + 2 if b is a T-vertex/blossom. +The label of a vertex is found by looking at the label of its +top-level containing blossom. +If v is a vertex inside a T-blossom, +label[v] is 2 iff v is reachable from an S-vertex outside the blossom. +Labels are assigned during a stage and reset after each augmentation.

i = 2 * nvertex; + var label = new Array(i); + while (i--) label[i] = 0;

If b is a labeled top-level blossom, +labelend[b] is the remote endpoint of the edge through which b obtained +its label, or -1 if b's base vertex is single. +If v is a vertex inside a T-blossom and label[v] === 2, +labelend[v] is the remote endpoint of the edge through which v is +reachable from outside the blossom.

i = 2 * nvertex; + var labelend = new Array(i); + while (i--) labelend[i] = -1;

If v is a vertex, +inblossom[v] is the top-level blossom to which v belongs. +If v is a top-level vertex, v is itthis a blossom (a trivial blossom) +and inblossom[v] === v. +Initially all vertices are top-level trivial blossoms.

i = nvertex; + var inblossom = new Array(i); + while (i--) inblossom[i] = i;

If b is a sub-blossom, +blossomparent[b] is its immediate parent (sub-)blossom. +If b is a top-level blossom, blossomparent[b] is -1.

i = 2 * nvertex; + var blossomparent = new Array(i); + while (i--) blossomparent[i] = -1;

If b is a non-trivial (sub-)blossom, +blossomchilds[b] is an ordered list of its sub-blossoms, starting with +the base and going round the blossom.

i = 2 * nvertex; + var blossomchilds = new Array(i); + while (i--) blossomchilds[i] = null;

If b is a (sub-)blossom, +blossombase[b] is its base VERTEX (i.e. recursive sub-blossom).

len = 2 * nvertex; + var blossombase = new Array(len); + for(i = 0; i < nvertex; ++i) blossombase[i] = i; + for(; i < len; ++i) blossombase[i] = -1;

If b is a non-trivial (sub-)blossom, +blossomendps[b] is a list of endpoints on its connecting edges, +such that blossomendps[b][i] is the local endpoint of blossomchilds[b][i] +on the edge that connects it to blossomchilds[b][wrap(i+1)].

i = 2 * nvertex; + var blossomendps = new Array(i); + while (i--) blossomendps[i] = null;

If v is a free vertex (or an unreached vertex inside a T-blossom), +bestedge[v] is the edge to an S-vertex with least slack, +or -1 if there is no such edge. +If b is a (possibly trivial) top-level S-blossom, +bestedge[b] is the least-slack edge to a different S-blossom, +or -1 if there is no such edge. +This is used for efficient computation of delta2 and delta3.

i = 2 * nvertex; + var bestedge = new Array(i); + while (i--) bestedge[i] = -1;

If b is a non-trivial top-level S-blossom, +blossombestedges[b] is a list of least-slack edges to neighbouring +S-blossoms, or null if no such list has been computed yet. +This is used for efficient computation of delta3.

i = 2 * nvertex; + var blossombestedges = new Array(i); + while (i--) blossombestedges[i] = null;

List of currently unused blossom numbers.

i = nvertex; + var unusedblossoms = new Array(i); + while (i--) unusedblossoms[i] = nvertex + i;

If v is a vertex, +dualvar[v] = 2 * u(v) where u(v) is the v's variable in the dual +optimization problem (multiplication by two ensures integer values +throughout the algorithm if all edge weights are integers). +If b is a non-trivial blossom, +dualvar[b] = z(b) where z(b) is b's variable in the dual optimization +problem.

len = 2 * nvertex; + var dualvar = new Array(len); + for(i = 0; i < nvertex; ++i) dualvar[i] = maxweight; + for(; i < len; ++i) dualvar[i] = 0;

If allowedge[k] is true, edge k has zero slack in the optimization +problem; if allowedge[k] is false, the edge's slack may or may not +be zero.

i = nedge; + var allowedge = new Array(i); + while (i--) allowedge[i] = false;

Queue of newly discovered S-vertices.

var queue = [];

Return 2 * slack of edge k (does not work inside blossoms).

var slack = function (k) { + var i = edges[k][0]; + var j = edges[k][1]; + var wt = edges[k][2]; + return dualvar[i] + dualvar[j] - 2 * wt; + };

Generate the leaf vertices of a blossom.

var blossomLeaves = function (b, fn) { + if (b < nvertex){ + if(fn(b)) return true; + } + else { + var len, i, t; + len = blossomchilds[b].length; + for(i = 0; i < len; ++i){ + t = blossomchilds[b][i]; + if (t < nvertex) { + if (fn(t)) return true; + } + else { + if (blossomLeaves(t, fn)) return true; + } + } + } + };

Assign label t to the top-level blossom containing vertex w +and record the fact that w was reached through the edge with +remote endpoint p.

var assignLabel = function (w, t, p) { + if (DEBUG) DEBUG('assignLabel(' + w + ',' + t + ',' + p + ')'); + var b = inblossom[w], e; + assert(label[w] === 0 && label[b] === 0); + label[w] = label[b] = t; + labelend[w] = labelend[b] = p; + bestedge[w] = bestedge[b] = -1; + if (t === 1){

b became an S-vertex/blossom; add it(s vertices) to the queue.

blossomLeaves(b, function(e){ queue.push(e); }); + if (DEBUG) DEBUG('PUSH ' + queue); + } + else if (t === 2){

b became a T-vertex/blossom; assign label S to its mate. +(If b is a non-trivial blossom, its base is the only vertex +with an external mate.)

var base = blossombase[b]; + assert(mate[base] >= 0); + assignLabel(endpoint[mate[base]], 1, mate[base] ^ 1); + } + + };

Trace back from vertices v and w to discover either a new blossom +or an augmenting path. Return the base vertex of the new blossom or -1.

var scanBlossom = function (v, w) { + if (DEBUG) DEBUG('scanBlossom(' + v + ',' + w + ')');

Trace back from v and w, placing breadcrumbs as we go.

var b, tmp, i; + var path = []; + var base = -1; + while (v !== -1 || w !== -1) {

Look for a breadcrumb in v's blossom or put a new breadcrumb.

b = inblossom[v]; + if (label[b] & 4) { + base = blossombase[b]; + break; + } + assert(label[b] === 1); + path.push(b); + label[b] = 5;

TODO should take a linked list prototype as template parameter + in order to simplify the implementation and allow better + parametrization as well as clarify the code

TODO an explicit satelite data storage emplacement should be allocated + in the vertices and edges in order to allow a more flexible usage + of this code

var sparse_graph_t = function(){

Object constructor

+

The main entry points in the graph object are the two dummy nodes [beg] and [end]. +Those allow us to write more generic code by handling corner cases implicitly. +They allow the addition of a single vertex to the graph in O(1). +Remark : Indeed the behaviour we want to get is the behaviour of a dll (doubly linked list).

+

vertices are small arrays where

+

[0] = the vertex label lab() +[1] = the vertex predecessor pred() +[2] = the vertex successor succ() +[3] = the edge list pointer e()

+

For the set vertices that have not been removed from the graph, +we define the 'youngest' vertex as the most recently added vertex of this set +and we define the 'oldest' vertex as the least recently added vertex of this set

+

Invariants

+

Given the graph is not empty:

+
+

[end][1] = pred of end = the youngest vertex +[beg][2] = succ of beg = the oldest vertex

+
+

Given a vertex v

+
+

v[1][2] = succ of pred of v = v +v[2][1] = pred of succ of v = v

+
var graph = function() { + + this.beg = [null, null, null]; + this.end = [null, this.beg, null]; + this.beg[2] = this.end; + + this.ebeg = [null, null, -1, null, null]; + this.eend = [null, null, -1, this.ebeg, null]; + this.ebeg[4] = this.eend; + + };

Prototype method to add a vertex to the graph with label h.

+

+The graph is extended

+

Parameters:

+
    +
  • h must be a label.
    (is the label)
    • +
graph.prototype.vadd = function ( h ) {

First the vertex is created and appended at the end of the dll. +Remember [end][1] was the previous last element +which could be [beg] if the graph was empty before the call. +After the assignation,

+
+

[end][1][1] is the previous [end][1] +[end] and [end][1] are sane +[end][1][1][2] is still pointing to [end]

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum -Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. -It is based on the "blossom" method for finding augmenting paths and -the "primal-dual" method for finding a matching of maximum weight, both -due to Jack Edmonds. -Some ideas came from "Implementation of algorithms for maximum matching -on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively -to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; -only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      var assert = function (condition) { - if (!condition) throw new Error('Assertion failed'); - }; - - var min = function (a, i, j) { - - var o = a[i]; - - while (--j > i) { - if (a[j] < o) o = a[j]; - } - - return o; - }; - - var zip = function (a, fn) { - var shortest = a[0].length < a[1].length ? a[0] : a[1]; - - shortest.map(function (_, i) { - if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; - }); - };
      var maxWeightMatching = function (edges, maxcardinality) { - var i, j, k, p, w, len; - - if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected -weighted graph given by "edges". If "maxcardinality" is true, -only maximum-cardinality matchings are considered as solutions.

      -

      Edges is a sequence of tuples (i, j, wt) describing an undirected -edge between vertex i and vertex j with weight wt. There is at most -one edge between any two vertices; no vertex has an edge to itthis. -Vertices are identified by consecutive, non-negative integers.

      -

      Return a list "mate", such that mate[i] === j if vertex i is -matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      -

      This function takes time O(n ** 3){

      Vertices are numbered 0 .. (nvertex-1). -Non-trivial blossoms are numbered nvertex .. (2nvertex-1) -Edges are numbered 0 .. (nedge-1). -Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints -(2k) and (2k+1) both belong to edge k. -Many terms used in the comments (sub-blossom, T-vertex) come from -the paper by Galil; read the paper before reading this code.

      Deal swiftly with empty graphs.

      If v is a vertex, -mate[v] is the remote endpoint of its matched edge, or -1 if it is single -(i.e. endpoint[mate[v]] is v's partner vertex). -Initially all vertices are single; updated during augmentation.

      If b is a top-level blossom, -label[b] is 0 if b is unlabeled (free); - 1 if b is an S-vertex/blossom; - 2 if b is a T-vertex/blossom. -The label of a vertex is found by looking at the label of its -top-level containing blossom. -If v is a vertex inside a T-blossom, -label[v] is 2 iff v is reachable from an S-vertex outside the blossom. -Labels are assigned during a stage and reset after each augmentation.

      If b is a labeled top-level blossom, -labelend[b] is the remote endpoint of the edge through which b obtained -its label, or -1 if b's base vertex is single. -If v is a vertex inside a T-blossom and label[v] === 2, -labelend[v] is the remote endpoint of the edge through which v is -reachable from outside the blossom.

      If b is a non-trivial (sub-)blossom, -blossomendps[b] is a list of endpoints on its connecting edges, -such that blossomendps[b][i] is the local endpoint of blossomchilds[b][i] -on the edge that connects it to blossomchilds[b][wrap(i+1)].

      i = 2 * nvertex; - var blossomendps = new Array(i); - while (i--) blossomendps[i] = null;

      If v is a free vertex (or an unreached vertex inside a T-blossom), -bestedge[v] is the edge to an S-vertex with least slack, -or -1 if there is no such edge. -If b is a (possibly trivial) top-level S-blossom, -bestedge[b] is the least-slack edge to a different S-blossom, -or -1 if there is no such edge. -This is used for efficient computation of delta2 and delta3.

      If b is a non-trivial top-level S-blossom, -blossombestedges[b] is a list of least-slack edges to neighbouring -S-blossoms, or null if no such list has been computed yet. -This is used for efficient computation of delta3.

      Adapted from http://jorisvr.nl/maximummatching.html +All credit for the implementation goes to Joris van Rantwijk [http://jorisvr.nl].

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum +Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. +It is based on the "blossom" method for finding augmenting paths and +the "primal-dual" method for finding a matching of maximum weight, both +due to Jack Edmonds. +Some ideas came from "Implementation of algorithms for maximum matching +on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively +to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; +only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      Compatibility

      var assert = function (condition) { + if (!condition) throw new Error('Assertion failed'); + }; + + var min = function (a, i, j) { + + var o = a[i]; + + while (--j > i) { + if (a[j] < o) o = a[j]; + } + + return o; + }; + + var zip = function (a, fn) { + var shortest = a[0].length < a[1].length ? a[0] : a[1]; + + shortest.map(function (_, i) { + if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; + }); + };
      var maxWeightMatching = function (edges, maxcardinality) { + var i, j, k, p, w, len; + + if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected +weighted graph given by "edges". If "maxcardinality" is true, +only maximum-cardinality matchings are considered as solutions.

      +

      Edges is a sequence of tuples (i, j, wt) describing an undirected +edge between vertex i and vertex j with weight wt. There is at most +one edge between any two vertices; no vertex has an edge to itthis. +Vertices are identified by consecutive, non-negative integers.

      +

      Return a list "mate", such that mate[i] === j if vertex i is +matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      +

      This function takes time O(n ** 3){

      Vertices are numbered 0 .. (nvertex-1). +Non-trivial blossoms are numbered nvertex .. (2nvertex-1) +Edges are numbered 0 .. (nedge-1). +Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints +(2k) and (2k+1) both belong to edge k. +Many terms used in the comments (sub-blossom, T-vertex) come from +the paper by Galil; read the paper before reading this code.

      Deal swiftly with empty graphs.

      if (!edges.length) return [];

      Count vertices + find the maximum edge weight.

      var nedge = edges.length; + var nvertex = 0; + var maxweight = 0; + + len = nedge; + while (len--) { + i = edges[len][0]; + j = edges[len][1]; + w = edges[len][2]; + + assert(i >= 0 && j >= 0 && i !== j); + if (i >= nvertex) nvertex = i + 1; + if (j >= nvertex) nvertex = j + 1; + + maxweight = Math.max(maxweight, w); + }

      If p is an edge endpoint, +endpoint[p] is the vertex to which endpoint p is attached. +Not modified by the algorithm.

      p = 2 * nedge; + var endpoint = new Array(p); + while (p--) endpoint[p] = edges[Math.floor(p / 2)][p % 2];

      If v is a vertex, +mate[v] is the remote endpoint of its matched edge, or -1 if it is single +(i.e. endpoint[mate[v]] is v's partner vertex). +Initially all vertices are single; updated during augmentation.

      i = nvertex; + var mate = new Array(i); + while (i--) mate[i] = -1;

      If b is a top-level blossom, +label[b] is 0 if b is unlabeled (free); + 1 if b is an S-vertex/blossom; + 2 if b is a T-vertex/blossom. +The label of a vertex is found by looking at the label of its +top-level containing blossom. +If v is a vertex inside a T-blossom, +label[v] is 2 iff v is reachable from an S-vertex outside the blossom. +Labels are assigned during a stage and reset after each augmentation.

      i = 2 * nvertex; + var label = new Array(i); + while (i--) label[i] = 0;

      If b is a labeled top-level blossom, +labelend[b] is the remote endpoint of the edge through which b obtained +its label, or -1 if b's base vertex is single. +If v is a vertex inside a T-blossom and label[v] === 2, +labelend[v] is the remote endpoint of the edge through which v is +reachable from outside the blossom.

      i = 2 * nvertex; + var labelend = new Array(i); + while (i--) labelend[i] = -1;

      If v is a vertex, +inblossom[v] is the top-level blossom to which v belongs. +If v is a top-level vertex, v is itthis a blossom (a trivial blossom) +and inblossom[v] === v. +Initially all vertices are top-level trivial blossoms.

      If b is a non-trivial (sub-)blossom, +blossomendps[b] is a list of endpoints on its connecting edges, +such that blossomendps[b][i] is the local endpoint of blossomchilds[b][i] +on the edge that connects it to blossomchilds[b][wrap(i+1)].

      i = 2 * nvertex; + var blossomendps = new Array(i); + while (i--) blossomendps[i] = null;

      If v is a free vertex (or an unreached vertex inside a T-blossom), +bestedge[v] is the edge to an S-vertex with least slack, +or -1 if there is no such edge. +If b is a (possibly trivial) top-level S-blossom, +bestedge[b] is the least-slack edge to a different S-blossom, +or -1 if there is no such edge. +This is used for efficient computation of delta2 and delta3.

      i = 2 * nvertex; + var bestedge = new Array(i); + while (i--) bestedge[i] = -1;

      If b is a non-trivial top-level S-blossom, +blossombestedges[b] is a list of least-slack edges to neighbouring +S-blossoms, or null if no such list has been computed yet. +This is used for efficient computation of delta3.

      If v is a vertex, +dualvar[v] = 2 * u(v) where u(v) is the v's variable in the dual +optimization problem (multiplication by two ensures integer values +throughout the algorithm if all edge weights are integers). +If b is a non-trivial blossom, +dualvar[b] = z(b) where z(b) is b's variable in the dual optimization +problem.

      If allowedge[k] is true, edge k has zero slack in the optimization +problem; if allowedge[k] is false, the edge's slack may or may not +be zero.

      i = nedge; + var allowedge = new Array(i); + while (i--) allowedge[i] = false;

      Queue of newly discovered S-vertices.

      var queue = [];

      Return 2 * slack of edge k (does not work inside blossoms).

      var slack = function (k) { + var i = edges[k][0]; + var j = edges[k][1]; + var wt = edges[k][2]; + return dualvar[i] + dualvar[j] - 2 * wt; + };

      Generate the leaf vertices of a blossom.

      var blossomLeaves = function (b, fn) { + if (b < nvertex){ + if(fn(b)) return true; + } + else { + var len, i, t; + len = blossomchilds[b].length; + for(i = 0; i < len; ++i){ + t = blossomchilds[b][i]; + if (t < nvertex) { + if (fn(t)) return true; + } + else { + if (blossomLeaves(t, fn)) return true; + } + } + } + };

      Assign label t to the top-level blossom containing vertex w +and record the fact that w was reached through the edge with +remote endpoint p.

      var assignLabel = function (w, t, p) { + if (DEBUG) DEBUG('assignLabel(' + w + ',' + t + ',' + p + ')'); + var b = inblossom[w], e; + assert(label[w] === 0 && label[b] === 0); + label[w] = label[b] = t; + labelend[w] = labelend[b] = p; + bestedge[w] = bestedge[b] = -1; + if (t === 1){

      b became an S-vertex/blossom; add it(s vertices) to the queue.

      blossomLeaves(b, function(e){ queue.push(e); }); + if (DEBUG) DEBUG('PUSH ' + queue); + } + else if (t === 2){

      b became a T-vertex/blossom; assign label S to its mate. +(If b is a non-trivial blossom, its base is the only vertex +with an external mate.)

      var base = blossombase[b]; + assert(mate[base] >= 0); + assignLabel(endpoint[mate[base]], 1, mate[base] ^ 1); + } + + };

      Trace back from vertices v and w to discover either a new blossom +or an augmenting path. Return the base vertex of the new blossom or -1.

      var scanBlossom = function (v, w) { + if (DEBUG) DEBUG('scanBlossom(' + v + ',' + w + ')');

      Given a vertex v

      +
      +

      v[1][2] = succ of pred of v = v +v[2][1] = pred of succ of v = v

      Prototype method to add a vertex to the graph with label h.

      +

      +The graph is extended

      +

      Parameters:

      +
        +
      • h must be a label.
        (is the label)
        • +
      graph.prototype.vadd = function ( h ) {

      First the vertex is created and appended at the end of the dll. +Remember [end][1] was the previous last element +which could be [beg] if the graph was empty before the call. +After the assignation,

      +
      +

      [end][1][1] is the previous [end][1] +[end] and [end][1] are sane +[end][1][1][2] is still pointing to [end]

      +
      this.end[1] = [h, this.end[1], this.end, [null, -1, null, null]];

      Adapted from http://jorisvr.nl/maximummatching.html +All credit for the implementation goes to Joris van Rantwijk [http://jorisvr.nl].

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum +Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. +It is based on the "blossom" method for finding augmenting paths and +the "primal-dual" method for finding a matching of maximum weight, both +due to Jack Edmonds. +Some ideas came from "Implementation of algorithms for maximum matching +on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively +to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; +only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      Compatibility

      var assert = function (condition) { + if (!condition) throw new Error('Assertion failed'); + }; + + var min = function (a, i, j) { + + var o = a[i]; + + while (--j > i) { + if (a[j] < o) o = a[j]; + } + + return o; + }; + + var zip = function (a, fn) { + var shortest = a[0].length < a[1].length ? a[0] : a[1]; + + shortest.map(function (_, i) { + if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; + }); + };
      var maxWeightMatching = function (edges, maxcardinality) { + var i, j, k, p, w, len; + + if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected +weighted graph given by "edges". If "maxcardinality" is true, +only maximum-cardinality matchings are considered as solutions.

      +

      Edges is a sequence of tuples (i, j, wt) describing an undirected +edge between vertex i and vertex j with weight wt. There is at most +one edge between any two vertices; no vertex has an edge to itthis. +Vertices are identified by consecutive, non-negative integers.

      +

      Return a list "mate", such that mate[i] === j if vertex i is +matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      +

      This function takes time O(n ** 3){

      Vertices are numbered 0 .. (nvertex-1). +Non-trivial blossoms are numbered nvertex .. (2nvertex-1) +Edges are numbered 0 .. (nedge-1). +Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints +(2k) and (2k+1) both belong to edge k. +Many terms used in the comments (sub-blossom, T-vertex) come from +the paper by Galil; read the paper before reading this code.

      Deal swiftly with empty graphs.

      if (!edges.length) return [];

      Count vertices + find the maximum edge weight.

      var nedge = edges.length; + var nvertex = 0; + var maxweight = 0; + + len = nedge; + while (len--) { + i = edges[len][0]; + j = edges[len][1]; + w = edges[len][2]; + + assert(i >= 0 && j >= 0 && i !== j); + if (i >= nvertex) nvertex = i + 1; + if (j >= nvertex) nvertex = j + 1; + + maxweight = Math.max(maxweight, w); + }

      If p is an edge endpoint, +endpoint[p] is the vertex to which endpoint p is attached. +Not modified by the algorithm.

      p = 2 * nedge; + var endpoint = new Array(p); + while (p--) endpoint[p] = edges[Math.floor(p / 2)][p % 2];

      If v is a vertex, +mate[v] is the remote endpoint of its matched edge, or -1 if it is single +(i.e. endpoint[mate[v]] is v's partner vertex). +Initially all vertices are single; updated during augmentation.

      i = nvertex; + var mate = new Array(i); + while (i--) mate[i] = -1;

      If b is a top-level blossom, +label[b] is 0 if b is unlabeled (free); + 1 if b is an S-vertex/blossom; + 2 if b is a T-vertex/blossom. +The label of a vertex is found by looking at the label of its +top-level containing blossom. +If v is a vertex inside a T-blossom, +label[v] is 2 iff v is reachable from an S-vertex outside the blossom. +Labels are assigned during a stage and reset after each augmentation.

      i = 2 * nvertex; + var label = new Array(i); + while (i--) label[i] = 0;

      If b is a labeled top-level blossom, +labelend[b] is the remote endpoint of the edge through which b obtained +its label, or -1 if b's base vertex is single. +If v is a vertex inside a T-blossom and label[v] === 2, +labelend[v] is the remote endpoint of the edge through which v is +reachable from outside the blossom.

      i = 2 * nvertex; + var labelend = new Array(i); + while (i--) labelend[i] = -1;

      If v is a vertex, +inblossom[v] is the top-level blossom to which v belongs. +If v is a top-level vertex, v is itthis a blossom (a trivial blossom) +and inblossom[v] === v. +Initially all vertices are top-level trivial blossoms.

      If b is a non-trivial (sub-)blossom, +blossomendps[b] is a list of endpoints on its connecting edges, +such that blossomendps[b][i] is the local endpoint of blossomchilds[b][i] +on the edge that connects it to blossomchilds[b][wrap(i+1)].

      i = 2 * nvertex; + var blossomendps = new Array(i); + while (i--) blossomendps[i] = null;

      If v is a free vertex (or an unreached vertex inside a T-blossom), +bestedge[v] is the edge to an S-vertex with least slack, +or -1 if there is no such edge. +If b is a (possibly trivial) top-level S-blossom, +bestedge[b] is the least-slack edge to a different S-blossom, +or -1 if there is no such edge. +This is used for efficient computation of delta2 and delta3.

      i = 2 * nvertex; + var bestedge = new Array(i); + while (i--) bestedge[i] = -1;

      If b is a non-trivial top-level S-blossom, +blossombestedges[b] is a list of least-slack edges to neighbouring +S-blossoms, or null if no such list has been computed yet. +This is used for efficient computation of delta3.

      If v is a vertex, +dualvar[v] = 2 * u(v) where u(v) is the v's variable in the dual +optimization problem (multiplication by two ensures integer values +throughout the algorithm if all edge weights are integers). +If b is a non-trivial blossom, +dualvar[b] = z(b) where z(b) is b's variable in the dual optimization +problem.

      The main entry points in the graph object are the two dummy nodes [beg] and [end]. +Those allow us to write more generic code by handling corner cases implicitly. +They allow the addition of a single vertex to the graph in O(1). +Remark : Indeed the behaviour we want to get is the behaviour of a dll (doubly linked list).

      +

      vertices are small arrays where

      Adapted from http://jorisvr.nl/maximummatching.html -All credit for the implementation goes to Joris van Rantwijk [http://jorisvr.nl].

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum -Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. -It is based on the "blossom" method for finding augmenting paths and -the "primal-dual" method for finding a matching of maximum weight, both -due to Jack Edmonds. -Some ideas came from "Implementation of algorithms for maximum matching -on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively -to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; -only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      Compatibility

      var assert = function (condition) { - if (!condition) throw new Error('Assertion failed'); - }; - - var min = function (a, i, j) { - - var o = a[i]; - - while (--j > i) { - if (a[j] < o) o = a[j]; - } - - return o; - }; - - var zip = function (a, fn) { - var shortest = a[0].length < a[1].length ? a[0] : a[1]; - - shortest.map(function (_, i) { - if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; - }); - };
      var maxWeightMatching = function (edges, maxcardinality) { - var i, j, k, p, w, len; - - if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected -weighted graph given by "edges". If "maxcardinality" is true, -only maximum-cardinality matchings are considered as solutions.

      -

      Edges is a sequence of tuples (i, j, wt) describing an undirected -edge between vertex i and vertex j with weight wt. There is at most -one edge between any two vertices; no vertex has an edge to itthis. -Vertices are identified by consecutive, non-negative integers.

      -

      Return a list "mate", such that mate[i] === j if vertex i is -matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      -

      This function takes time O(n ** 3){

      Vertices are numbered 0 .. (nvertex-1). -Non-trivial blossoms are numbered nvertex .. (2nvertex-1) -Edges are numbered 0 .. (nedge-1). -Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints -(2k) and (2k+1) both belong to edge k. -Many terms used in the comments (sub-blossom, T-vertex) come from -the paper by Galil; read the paper before reading this code.

      Deal swiftly with empty graphs.

      If v is a vertex, -mate[v] is the remote endpoint of its matched edge, or -1 if it is single -(i.e. endpoint[mate[v]] is v's partner vertex). -Initially all vertices are single; updated during augmentation.

      i = nvertex; - var mate = new Array(i); - while (i--) mate[i] = -1;

      If b is a top-level blossom, -label[b] is 0 if b is unlabeled (free); - 1 if b is an S-vertex/blossom; - 2 if b is a T-vertex/blossom. -The label of a vertex is found by looking at the label of its -top-level containing blossom. -If v is a vertex inside a T-blossom, -label[v] is 2 iff v is reachable from an S-vertex outside the blossom. -Labels are assigned during a stage and reset after each augmentation.

      i = 2 * nvertex; - var label = new Array(i); - while (i--) label[i] = 0;

      If b is a labeled top-level blossom, -labelend[b] is the remote endpoint of the edge through which b obtained -its label, or -1 if b's base vertex is single. -If v is a vertex inside a T-blossom and label[v] === 2, -labelend[v] is the remote endpoint of the edge through which v is -reachable from outside the blossom.

      i = 2 * nvertex; - var labelend = new Array(i); - while (i--) labelend[i] = -1;

      If v is a free vertex (or an unreached vertex inside a T-blossom), -bestedge[v] is the edge to an S-vertex with least slack, -or -1 if there is no such edge. -If b is a (possibly trivial) top-level S-blossom, -bestedge[b] is the least-slack edge to a different S-blossom, -or -1 if there is no such edge. -This is used for efficient computation of delta2 and delta3.

      If b is a non-trivial top-level S-blossom, -blossombestedges[b] is a list of least-slack edges to neighbouring -S-blossoms, or null if no such list has been computed yet. -This is used for efficient computation of delta3.

      If v is a vertex, -dualvar[v] = 2 * u(v) where u(v) is the v's variable in the dual -optimization problem (multiplication by two ensures integer values -throughout the algorithm if all edge weights are integers). -If b is a non-trivial blossom, -dualvar[b] = z(b) where z(b) is b's variable in the dual optimization -problem.

      If allowedge[k] is true, edge k has zero slack in the optimization -problem; if allowedge[k] is false, the edge's slack may or may not -be zero.

      i = nedge; - var allowedge = new Array(i); - while (i--) allowedge[i] = false;

      Queue of newly discovered S-vertices.

      var queue = [];

      Return 2 * slack of edge k (does not work inside blossoms).

      var slack = function (k) { - var i = edges[k][0]; - var j = edges[k][1]; - var wt = edges[k][2]; - return dualvar[i] + dualvar[j] - 2 * wt; - };

      Generate the leaf vertices of a blossom.

      Assign label t to the top-level blossom containing vertex w -and record the fact that w was reached through the edge with -remote endpoint p.

      var assignLabel = function (w, t, p) { - if (DEBUG) DEBUG('assignLabel(' + w + ',' + t + ',' + p + ')'); - var b = inblossom[w], e; - assert(label[w] === 0 && label[b] === 0); - label[w] = label[b] = t; - labelend[w] = labelend[b] = p; - bestedge[w] = bestedge[b] = -1; - if (t === 1){

      b became an S-vertex/blossom; add it(s vertices) to the queue.

      var base = blossombase[b]; - assert(mate[base] >= 0); - assignLabel(endpoint[mate[base]], 1, mate[base] ^ 1); - } - - };

      Trace back from vertices v and w to discover either a new blossom -or an augmenting path. Return the base vertex of the new blossom or -1.

      var scanBlossom = function (v, w) { - if (DEBUG) DEBUG('scanBlossom(' + v + ',' + w + ')');

      Given a vertex v

      -
      -

      v[1][2] = succ of pred of v = v -v[2][1] = pred of succ of v = v

      Prototype method to add a vertex to the graph with label h.

      -

      -The graph is extended

      -

      Parameters:

      -
        -
      • h must be a label.
        (is the label)
        • -
      graph.prototype.vadd = function ( h ) {

      First the vertex is created and appended at the end of the dll. -Remember [end][1] was the previous last element -which could be [beg] if the graph was empty before the call. -After the assignation,

      -
      -

      [end][1][1] is the previous [end][1] -[end] and [end][1] are sane -[end][1][1][2] is still pointing to [end]

      -
      this.end[1] = [h, this.end[1], this.end, [null, -1, null, null]];

      update [end][1][1][2] to fix the invariant break

      Adapted from http://jorisvr.nl/maximummatching.html -All credit for the implementation goes to Joris van Rantwijk [http://jorisvr.nl].

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum -Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. -It is based on the "blossom" method for finding augmenting paths and -the "primal-dual" method for finding a matching of maximum weight, both -due to Jack Edmonds. -Some ideas came from "Implementation of algorithms for maximum matching -on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively -to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; -only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      Compatibility

      var assert = function (condition) { - if (!condition) throw new Error('Assertion failed'); - }; - - var min = function (a, i, j) { - - var o = a[i]; - - while (--j > i) { - if (a[j] < o) o = a[j]; - } - - return o; - }; - - var zip = function (a, fn) { - var shortest = a[0].length < a[1].length ? a[0] : a[1]; - - shortest.map(function (_, i) { - if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; - }); - };
      var maxWeightMatching = function (edges, maxcardinality) { - var i, j, k, p, w, len; - - if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected -weighted graph given by "edges". If "maxcardinality" is true, -only maximum-cardinality matchings are considered as solutions.

      -

      Return a list "mate", such that mate[i] === j if vertex i is -matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      The main entry points in the graph object are the two dummy nodes [beg] and [end]. -Those allow us to write more generic code by handling corner cases implicitly. -They allow the addition of a single vertex to the graph in O(1). -Remark : Indeed the behaviour we want to get is the behaviour of a dll (doubly linked list).

      Adapted from http://jorisvr.nl/maximummatching.html +All credit for the implementation goes to Joris van Rantwijk [http://jorisvr.nl].

      Original introduction below

      Weighted maximum matching in general graphs.

      The algorithm is taken from "Efficient Algorithms for Finding Maximum +Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. +It is based on the "blossom" method for finding augmenting paths and +the "primal-dual" method for finding a matching of maximum weight, both +due to Jack Edmonds. +Some ideas came from "Implementation of algorithms for maximum matching +on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

      A C program for maximum weight matching by Ed Rothberg was used extensively +to validate this new code.

      var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {

      If assigned, DEBUG(str) is called with lots of debug messages.

      var DEBUG = debug ? function(s){ console.log('DEBUG:', s); } : null;

      Check delta2/delta3 computation after every substage; +only works on integer weights, slows down the algorithm to O(n^4).

      if (CHECK_DELTA === undefined) CHECK_DELTA = false;

      Check optimality of solution before returning; only works on integer weights.

      if (CHECK_OPTIMUM === undefined) CHECK_OPTIMUM = true;

      Compatibility

      var assert = function (condition) { + if (!condition) throw new Error('Assertion failed'); + }; + + var min = function (a, i, j) { + + var o = a[i]; + + while (--j > i) { + if (a[j] < o) o = a[j]; + } + + return o; + }; + + var zip = function (a, fn) { + var shortest = a[0].length < a[1].length ? a[0] : a[1]; + + shortest.map(function (_, i) { + if (fn.apply(null, a.map(function(array){ return array[i]; }))) return; + }); + };
      var maxWeightMatching = function (edges, maxcardinality) { + var i, j, k, p, w, len; + + if (maxcardinality === undefined) maxcardinality = false;

      Compute a maximum-weighted matching in the general undirected +weighted graph given by "edges". If "maxcardinality" is true, +only maximum-cardinality matchings are considered as solutions.

      +

      Edges is a sequence of tuples (i, j, wt) describing an undirected +edge between vertex i and vertex j with weight wt. There is at most +one edge between any two vertices; no vertex has an edge to itthis. +Vertices are identified by consecutive, non-negative integers.

      +

      Return a list "mate", such that mate[i] === j if vertex i is +matched to vertex j, and mate[i] === -1 if vertex i is not matched.

      +

      This function takes time O(n ** 3){

      Vertices are numbered 0 .. (nvertex-1). +Non-trivial blossoms are numbered nvertex .. (2*nvertex-1)

      Edges are numbered 0 .. (nedge-1). +Edge endpoints are numbered 0 .. (2nedge-1), such that endpoints +(2k) and (2*k+1) both belong to edge k.

      TODO should take a linked list prototype as template parameter + in order to simplify the implementation and allow better + parametrization as well as clarify the code

      var sparse_graph_t = function(){

      Object constructor

      +

      The main entry points in the graph object are the two dummy nodes [beg] and [end]. +Those allow us to write more generic code by handling corner cases implicitly. +They allow the addition of a single vertex to the graph in O(1). +Remark : Indeed the behaviour we want to get is the behaviour of a dll (doubly linked list).

      +

      vertices are small arrays where

      +

      [0] = the vertex label lab() +[1] = the vertex predecessor pred() +[2] = the vertex successor succ() +[3] = the edge list pointer e()

      +

      For the set vertices that have not been removed from the graph, +we define the 'youngest' vertex as the most recently added vertex of this set +and we define the 'oldest' vertex as the least recently added vertex of this set

      +

      Invariants

      +

      Given the graph is not empty:

      +
      +

      [end][1] = pred of end = the youngest vertex +[beg][2] = succ of beg = the oldest vertex

      +
      +

      Given a vertex v

      +
      +

      v[1][2] = succ of pred of v = v +v[2][1] = pred of succ of v = v

      +
      var graph = function() { + + this.beg = [null, null, null]; + this.end = [null, this.beg, null]; + this.beg[2] = this.end; + + this.ebeg = [null, null, -1, null, null]; + this.eend = [null, null, -1, this.ebeg, null]; + this.ebeg[4] = this.eend; + + };

      Prototype method to add a vertex to the graph with label h.

      +

      +The graph is extended

      +

      Parameters:

      +
        +
      • h must be a label.
        (is the label)
        • +
      graph.prototype.vadd = function ( h ) {

      First the vertex is created and appended at the end of the dll. +Remember [end][1] was the previous last element +which could be [beg] if the graph was empty before the call. +After the assignation,

      +
      +

      [end][1][1] is the previous [end][1] +[end] and [end][1] are sane +[end][1][1][2] is still pointing to [end]

+// on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.

Gabow, Standford Ph.D. thesis, 1973.

                                                                                          A C program for maximum weight matching by Ed Rothberg was used extensively -to validate this new code.

                                                                                          var wblossom_n3_t = function (debug, CHECK_OPTIMUM, CHECK_DELTA) {
