15．Four to one to the computer．That was the score．AlphaGo，a program developed by Google's London-based artificial intelligence （AI） team Deep-Mind，has just beaten a human at a really complicated game．The field of honor is a Go（围棋） board in Seoul （首尔），South Korea．Lee Sedol （李世石），a South Korean，is a world Go champion and is considered the game's most outstanding player．But he was defeated by AlphaGo．
The contest has drawn tens of thousands of online spectators who have followed the matches live on the Internet．Videos of the competition have received more than four million views since the contest began on March 9．The five-game contest took a week in all．While at a pre-match press conference，Lee said he was confident he would win five to nil （零分） or，at least，four to one，he defeated AlphaGo only once in the fourth game．
"When I look back on the three games，even if I were to go back and redo the first game，I think I would not be able to win because I misjudged AlphaGo，"Lee said at a post-game press conference on March12，following his third straight defeat．Go，which originated in China thousands of years ago，is played on a 19x 19board with black and white stones （棋子）．The board's size means the number of possible moves is greater than the number of atoms in the observable universe．Go is said to be the only game that truly balances the left and right sides of the brain．According to Demis Hassabis，the leading founder of Deep Mind，Go poses a more difficult programming challenge than chess．AlphaGo's success marked the most significant milestone ever in AI．
Yet AlphaGo is only going to get smarter as it gathers more data from which it learns．Asked whether there was a ceiling to its abilities，Hassabis said he did not know．"If there is，we haven't found it yet．"
