As in the previous nine editions, you have 72 hours (starting July 20, 12:00 noon CEST) to show that your favorite programming language (or your team) is better than all others! The ICFP Programming Contest is organised as part of the International Conference on Functional Programming in the hopes of showing off functional programming, but contestants can use any language(s) they like. Previous winners have included Cilk, OCaml (3x), Haskell (3x), C++ and 2D. Previous problems have ranged from programming intelligent ants to cracking the secrets of an ancient civilization. This year's contest seems to have something to do with visitors from outer space."
