This is correct, and the equations in the movie were very much real. I thought it was funnily obvious when he called it "The algorithm for rating chess players"

This is correct, and the equations in the movie were very much real. I thought it was funnily obvious when he called it "The algorithm for rating chess players", knowing what ELO was.
Here's "The Algorithm": http://imgur.com/e5myT http://imgur.com/e5myT
EDIT: In the intrest in contribution to discussion, two other methods for ranking are the Colley matrix from the BCS (http://www.colleyrankings.com/method.html http://www.colleyrankings.com/method.html) and I have used PageRank for a similar purpose before (http://michaelnielsen.org/blog/lectures-on-the-google-technology-stack-1-introduction-to-pagerank/ http://michaelnielsen.org/blog/lectures-on-the-google-techno...).
- carbocation 16y agoNitpick: it's "Elo" because it's a man's last name, not an acronym. Also, the Colley matrix homepage has this odd bit of text: Please note: This method is copyright. That's not how you protect algorithms.
- kersny 16y agoAh, yes, my mistake. And I wonder how that copyright works... it seems as though these guys: http://digital.ipcprintservices.com/publication/?i=34502&p=17 http://digital.ipcprintservices.com/publication/?i=34502&... used the method for their project, although I don't think they made any money off of it. That article also describes Colley's matrix very well.
