DeepMind’s AI Program AlphaGo Beats Go World Champion Lee Se-dol

In the first of five scheduled games, the artificial intelligence program developed by Google’s DeepMind has beaten the world champion Go player Lee Sed-ol in what is seen as a milestone for AI research.

The game, which took place in the Four Seasons Hotel in Seoul, South Korea, took three-and-a-half hours to complete with Lee resigning with over 28 minutes left on his game clock. Speaking after the game, Lee said: "I was very surprised. I didn't expect to lose. [But] I didn't think AlphaGo would play the game in such a perfect manner."
