Machinist: Tech Blog, Tech News, Technology Articles - Salon

Scientists at the University of Alberta report that they've built an unbeatable checkers-playing computer. Their machine, Chinook, has solved checkers: It proves that if two players play perfectly, making no mistakes, the game of checkers will result in a draw.

The proof required analyzing 500 billion billion checkers positions -- 5 x 1020 -- a computational process that began in 1989 and has been running on hundreds of processors almost continuously since. Chinook now knows everything about checkers, the perfect response to any move, and the best that any human can do is drive Chinook to a draw. You can never win.
