AlphaGo Wins Game One Against World Go Champion

Last night Google's AI AlphaGo won the first in a five-game series against the world's best Go player, in Seoul, South Korea. The success comes just five months after a slightly less experienced version of the same program became the first machine to defeat any Go professional by winning five games against the European champion. This victory was far more impressive though because it came at the expense of Lee Sedol, 33, who has dominated the ancient Chinese game for a decade. The European champion, Fan Hui, is ranked only 663rd in the world. And the machine, by all accounts, played a noticeably stronger game than it did back in October, evidence that it has learned much since then.
