I like that page. Well written and amusing to see how long some of these solutions took back then. Most I ever read on this problem was Knuth's Dancing Links. My small attempt at it is here: http://taeric.github.io/DancingLinks.html

I posted your page as a submission hoping to get a discussion on it. Apologies for not asking first. Please let me know if you want me to try and remove the submission.
