Games and artificial intelligence have always gone hand in hand. AI has permeated all kinds of non-trivial games, even going as far back as the original Pac-man arcade game. Now, computer scientists are turning the tables around, sort of. More and more researchers are actually using games to fuel and aid artificial intelligence research, most of the time by beating the game. But Project AIX from Microsoft Research is doing something different with Minecraft. It is using the open, world building game to let an AI learn how to climb a mountain. Without falling into a pool of lava.
