the computer may apprestarsi to win his final battle against the intelligence and human imagination. The Google software AlphaGo Wednesday defeated the world champion of the ancient Chinese game Go: This is the South Korean Lee Sedol, 33 years. Go is considered one of the most difficult board games in the world, given the huge amount of possible moves. Is so far believed that the man was favored over the machine, thanks to his imagination.
The AlphaGo software, developed by Google DeepMind on the mechanisms of the human brain model, has also demolished this limit. Google’s computers had already defeated 5 games to 0 the European go champion, but Lee Sedol was another opponent: professional player since he is 12 years old, has won 18 times the world championship. A Lee, who played from Seoul, are 4 other matches, up to Tuesday, March 15, to seek revenge. And to restore the primacy of imagination and human intelligence.
“I am very surprised because I did not think I would have lost the game – said the player in the flesh -. A mistake I made at the beginning lasted until the end. ” Lee added that the initial strategy AlphaGo was “excellent” and was amazed by an unconventional move of the software, that a human would not do.

two players must alternately placing black and white pieces (called “stones”) on empty intersections of the board. The aim of the game is the control of a
You can in fact capture a stone or a group of enemy stones by surrounding them completely with their stones, so that they have no adjacent free intersections.

Players try to satisfy both the offensive and defensive needs and choose among the priorities tactics and their strategic plans. The game ends when the players “pass” consecutively, indicating that neither of them can increase its territory or reduce his opponent’s.
