A computer programme has won a game of Go against the world's best player, in a huge breakthrough for artificial intelligence.

Google’s AlphaGo computer has beaten South Korean human and Go champion Lee Sedol in the first of five matches.

The Deepmind-based computer's victory in the complex Chinese game marks a major event in the development of artificial intelligence — the game depends hugely in intuition, since there are so many possibilities, and so mastery of the game was previously thought to be a human skill.

The game is said to be one of the most creative and complicated in the world, and usually takes years for even humans to master.
