Thanks! I think we should also add some reference to their specific publication that we mention here. And is it certain that we should only mention Shamos, but not Hoey?

I'm not sure who to credit. One publication is from Shamos, one from Shamos & Hoey. The textbook says the algorithm is due to Shamos.

I've checked the publication by Shamos. The corresponding section in his article references the joint article with Hoey.

I think we should attribute both authors, and also put a link to the original article.
