Google's DeepMind goes undercover to battle gamers

Gamers in Europe are being invited to take on a bot developed by some of the world's leading artificial intelligence researchers. But there's a twist: players will not be told when they have been pitted against it. The tests are being carried out by DeepMind, the London-based AI company that previously created a program that defeated the world's top Go players. In this case, the challenge involves the sci-fi video game Starcraft II. It is seen as being a more complex task, since players can only get a partial overview of what their opponent is doing, unlike the Chinese board game Go where all the pieces are on show.
