It is a milestone in the development of artificial intelligence: A Google software has the European champion in the ancient Asian board game Go, Fan Hui beaten. All five games won the machine.

The Go-rules are simple. The two players alternately placing black and white stones on the grid pattern of a game board in order to control the largest possible area. Go is considered much more challenging for computer programs than about chess. Because with the most originating from the ancient China game you have to expect dramatically more possible moves. “The number of configurations on the board is higher than the atoms in the universe,” wrote Google researcher Demis Hassabis the company blog.

In the 1990s, computer people could beat in board games like Backgammon first. The rapid progress of artificial intelligence culminated in 1997 when the IBM computer Deep Blue beat the world chess champion Garry Kasparov.

However, it took almost another 20 years before a machine could defeat professional Go player. The game is highly complex and is based as opposed to chess heavily on intuition. “If you ask great Go players why they made a particular train, they sometimes say: ‘It has felt right’,” said Hassabis.

Now awaits the “Roger Federer of Go”

The Google software developed at AlphaGo solves the challenge in that it predicts the likely characteristics of the human opponent and locks to that. You have two “neural networks” with similar compounds as in million nerve cells, it said in the blog post.

First, the machine got 30 million plays of experts for evaluation. After that, they had been able to predict the next train the people in 57 percent of cases. Subsequently, the networks of AlphaGo have played each other thousands of games in order to improve. In tests against other Go programs Google software have won 499 of 500 matches.
