DeepMind Achieves Holy Grail: An AI That Can Master Games Like Chess and Go Without Human Help

AlphaZero, a general-purpose game-playing system, quickly taught itself to be the best player ever in Go, chess and Shogi DeepMind, the London-based subsidiary of Alphabet, has created a system that can quickly master any game in the class that includes chess, Go, and Shogi, and do so without human guidance. The system, called AlphaZero, began its life last year by beating a DeepMind system that had been specialized just for Go. That earlier system had itself made history by beating one of the world’s best Go players, but it needed human help to get through a months-long course of improvement. AlphaZero trained itself—in just 3 days. Illustration: Science AlphaZero, playing White against Stockfish, began by identifying four candidate moves. After 1,000 simulations, it rejected the moves marked in red; after another 100,000 simulations, it chose the move marked in green over the one marked in orange. AlphaZero went on to win, thanks in large part to having opened the diagonal for its bishop. The research, published today Continue reading DeepMind Achieves Holy Grail: An AI That Can Master Games Like Chess and Go Without Human Help
