One of my first jobs during the dotcom boom was a gaming website that ran tournaments and analyzed statistics. Coming up with algorithms for round robin, single, and double elimination tournaments was one of the first things I did.

A more fun problem is to come up with an algorithm to page a double or single elimination tournament with a large number of seeds. You can of course just do it by hand, but it's more fun if you can configure how many rounds and pairings to show on each page.

Glad we could help.
