In this 2016 GDC session, programmer Nathan Sturtevant covers the mathematics of counting with combinations and permutations, and how game devs can employ it in their own projects.
It was a rich, technical talk that delved deep into key topics like how to compute perfect hash functions (rankings and unrankings) that allow programmers to convert to and from the index of a permutation/combination and an actual game state.
If you're a game programmer or you just have a passion for math, take advantage of the fact that Sturtevant's talks is now available to watch for free via the official GDC YouTube channel!
