Google's AI beats human champion at Go

In what they called a milestone achievement for artificial intelligence, scientists said on Wednesday they have created a computer program that beat a professional human player at the complex board game called Go, which originated in ancient China. The feat recalled IBM supercomputer Deep Blue's 1997 match victory over chess world champion Garry Kasparov. But Go, a strategy board game most popular in places like China, South Korea and Japan, is vastly more complicated than chess. "Go is considered to be the pinnacle of game AI research," said artificial intelligence researcher Demis Hassabis of Google DeepMind, the British company that developed the AlphaGo program. "It's been the grand challenge, or holy grail if you like, of AI since Deep Blue beat Kasparov at chess."
