Google's AI wins 3rd straight victory over world's top go player
SEOUL, March 12, Kyodo
AlphaGo, Google's artificial intelligence system, won its third straight game against South Korean world go champion Lee Se Dol on Saturday, claiming overall match victory and securing a $1 million prize to be donated to charity.
AlphaGo, which last year won 5-0 in a formal match against the reigning European Champion Fan Hui to become the first program to ever beat a professional go player in an even game, this time bested Lee, the grandmaster representing humankind, in a best-of-five series held at a Seoul hotel.
The remaining two matches will be held on Sunday and Tuesday to determine the final match score.
Lee, 33, who debuted as a professional player at age 12 and is regarded as the best go player of the past decade with 18 world titles under his belt, lost to the AI system developed by London-based Google DeepMind by giving up after 176 moves.
Go, which originated in China more than 2,500 years ago, is considered to be more complex than chess. According to Google, there are more possible positions than there are atoms in the universe.
Players take turns to place black or white stones on a board, trying to capture the opponent's stones or surround empty space to make points of territory.
