The machine’s victory is being likened to the defeat of reigning world chess champion Garry Kasparov in 1997 by IBM’s Deep Blue computer, which became a milestone in the advance of artificial intelligence over the human mind. Go, however, is more complex than chess with an infinitely greater number of potential moves, so experts were surprised to find that computer scientists had invented a suite of artificial intelligence (AI) algorithms that taught the computer how to win against Europe’s top player.

A match against the current world Go champion, Lee Sedol from South Korea, is now scheduled for March. -- In tests against other Go computer games on the market, AlphaGo won all but one out of 500 games, even when other programs were given a head-start with pieces already positioned on the board. Mr Silver said the neural networks were able to learn by themselves, unlike the “supervised” training of other artificial intelligence algorithms. “It learns in a human-like manner but it still takes a lot of practice.
