Google’s Alpha Go software beats human in Go championship

Google`s computer programme AlphaGo defeated its human opponent, South Korean Go champion Lee Sedol, on Wednesday in the first game of a historic five-game match between human and computer.AlphaGo`s victory in the ancient Chinese board game is a breakthrough for artificial intelligence, showing the program developed by Google DeepMind has mastered one of the most creative and complex games ever devised.Commentators said the match was close, with both AlphaGo and Lee making some mistakes. The result was unpredictable until near the end.Lee’s loss was a shock to South Koreans and Go fans. The 33-year-old initially was confident of a sweeping victory two weeks ago, but sounded less optimistic a day before the match.‘I was very surprised because I did not think that I would lose the game. A mistake I made at the very beginning lasted until the very last,’ said Lee, who has won 18 world championships since becoming a professional Go player at the age of 12.Lee said AlphaGo`s strategy was "excellent`` from the beginning.Yoo Chang-hyuk, another South Korean Go master who commentated on the game, described the result as a big shock said that Lee appeared to have been shaken at one point.Hundreds of thousands of people watched the game live on TV and YouTube. The remaining four more matches will end on Tuesday.Computers conquered chess in 1997 in a match between IBM`s Deep Blue and chess champion Garry Kasparov, leaving go as ‘the only game left above chess’ Demis Hassabis, Google DeepMind’s CEO, said before the game.Top human players rely heavily on intuition and feelings to choose among a near-infinite number of board positions in go, making the game extremely challenging for the artificial intelligence community.
