Google's 'godlike' AlphaGo AI retires from competitive Go

The Google-owned computer algorithm AlphaGo is retiring from playing humans in the ancient Chinese game of Go after defeating the world's top player this week. AlphaGo defeated 19-year-old world number one Ke Jie of China on Saturday to sweep a three-game series that was closely watched as a measure of how far artificial intelligence (AI) has come. Ke Jie anointed the program as the new'Go god' after his defeat. AlphaGo last year became the first computer programme to beat an elite player in a full Go match, and its successes have been hailed as groundbreaking due to the game's complexity. Go has an incomputable number of moves, putting a premium on human-like'intuition' and strategy.
