Computer wins final game against Go master

The Google supercomputer AlphaGo won the final game of its five-match challenge against South Korean Go grandmaster Lee Se-dol on Tuesday, to take the series 4-1.

After Lee managed to pull one back for humanity in game four, AlphaGo returned to its best destructive form, using the much-hyped "intuitive" artificial intelligence of its formidable neural networks to outwit the 33-year-old Lee.

A visibly upset Lee held his head in his hands at the table after resigning at the end of a five-hour battle.
