Computers can now add the game of Go to the list of board games they’ve mastered and beaten a human player at.
AlphaGo, a program created by Google’s London-based AI company, DeepMind, beat Fan Hui, the European Go champion, in five back-to-back matches. As reported by Nature, it has since gone on to win 99.8% of its matches against other programs, and has a match against South Korean professional Lee Sedol scheduled for March.
To master Go, DeepMind’s A.I. program studied 30 million positions from expert level games, then played against itself across 50 computers. It got better with each game it played, putting in on par with other Go programs, but DeepMind then gave it the ability to examine and interpret Go boards in order to pick its next move.
