“DeepMind’s AlphaGo program will test its artificial intelligence capabilities in May against top Go player Ke Jie. The match of three games in Wuzhen, China, between AlphaGo and the Chinese player comes about a year after the computer program beat by 4-1 a key player, the South Korean Lee Se-dol, in a game that is regarded as involving more complex strategy than chess. During the game, players take turns placing black or white pieces, called “stones,” on the 19-by-19 line grid. The aim is to capture the opponent’s stones by surrounding them and encircling more empty space as territory. AlphaGo has been seen as a major contender because of its ability to learn from its experience, sometimes resulting in far-from-human but nevertheless successful moves.”
