The official Halite Competition is over!

Halite's final rankings closed on February 16, 2017. Thank you to our 1500+ competitors!

Congratulations to mzotkiew, Halite's winner. Congrats also to the rest of the top 10: shummie, erdman, timfoden, curbin, PeppiKokki, DexGroves, nmalaguti, moonbirth, and ewirkerman. You can see some of their post-mortems and bot source code here.

Two Sigma plans to release another programming competition in the future. Stay tuned!

Halite is an artificial intelligence programming challenge.

Players control a bot using the programming language of their choice. Bots fight for control of a 2D grid. The bot with the most territory at the end wins. Victory will require micromanaging of the movement of your pieces, optimizing your bot's combat ability, and braving a branching factor billions of times higher than that of Go.
