Human Go champion scores 1st win over machine after 3 losses
SEOUL, South Korea (AP) — A champion Go player has scored his first win over Go-playing computer software after losing three straight times.
Lee Sedol's victory Sunday over AlphaGo in the ancient Chinese game served as a reminder that Google's Go-playing program is not perfect and has room for improvement.
AlphaGo — the first computer system to defeat a top Go player — had already clinched the best-of-five series and the $1 million prize, which will be donated to charity.
South Korean commentators could not hide their excitement three hours into the match when it became clear that Lee would finally notch a win. Go fans whose pride was crushed by the earlier defeats cheered the result.
Prior to the series, Go fans believed that the game would prove too complex for the machine.
