Google's Artificial Intelligence Software Wins Go Contest


A computer program built by Google has defeated one of the best players in the world in the Chinese board game Go.  The South Korean Go champion Lee Se-dol lost his game to a computer program that is based on Google's Deepmind , its artificial intelligence software. The match between a human and a computer was a test to find out where technology stands on artificial intelligence.

Go is an ancient game that was first played in China thousands of years ago. It is about placing black and white stones on a square board . The aim is to surround your opponent and control the board.  Go is considered to be much more complex than chessWhereas in chess there are 20 possible moves a player can make, there are over 200 in Go. According to one game expert, a Go board has more possible configurations than there are atoms in the universe.

In contrast to chess, Go is played more with intuition than with brutal calculation. That is why a computer has, up to now , never been able to play as well as a human. However, the first victory for the artificial intelligence software  came in 2015, when AlphaGo, as Google's program is called,  defeated the European Go champion in five straight games.

20 years ago computers, for the first time, beat humans at chess.  In 1997 IBM's Deep  Blue won against world chess champion Gary Kasparov.



Google researchers spent two years creating AlphaGo in a lab in London. They claim that the program learns the game by itself and becomes better as time goes on. But even they were surprised when the software defeated the world's number one. They thought that it would take at least ten more years before any form of artificial intelligence could be better than a human.

At a press conference Lee Se-dol said that he never thought he would lose . He was impressed at how well the computer played the game.
