AlphaGo, Google’s artificially intelligent Go-playing computer has secured its victory against Lee Se-dol, the 18 times world Go champion by winning the third straight game of a five-game match in Seoul. AlphaGo is a program developed by DeepMind, the British AI company Google acquired in 2014.
Go is an ancient Chinese board game played by two who take turns putting black or white stones on a 10-by-19 grid. Using own stones, one has to surround the opponent’s stones to win the game. Despite identical breakthroughs in other games like checkers and chess, Go was never considered to be played by a computer. However, Go’s simple rules and extended possibilities have made it one of the most researched landmarks in the field of AI.
Though Mr. Lee has led most of the match in the 1st match of the series, AlphaGo managed to make up a strong lead in its closing stages and won by a very narrow margin. However, he became speechless after losing the second match. According to him, AlphaGo played a “nearly perfect game.”
The third match was the complicated one to follow. Lee Se-dol had brought his best game. From the very beginning, he played very quickly and he played safe. It was a professional game and AlphaGo had won again “in great style.” It capably navigated tricky situations known as ko, which didn’t come up in the previous two matches.
“To be honest we are a bit stunned and speechless,” said DeepMind chief executive Demis Hassabis. “AlphaGo can compute tens of thousand positions a second, but it’s amazing that Lee Se-dol is able to compete with that and push AlphaGo to the limit. We came here to challenge Lee Se-dol because we wanted to see what AlphaGo was capable of, and his amazing genius and creative skills have done that.”
After losing the game Mr. Lee apologized to his fan. However, he requested people to continue showing interest for the rest of the games. According to 9-dan pro player and match commentator Michael Redmond said, “I believe [Lee] would have been difficult to beat today by any other top professional.” According to him, AlphaGo is a “work of art” and could revolutionize the game in future.

Using an advanced system based on deep neural networks and machine learning DeepMind’s AlphaGo AI program has gone further than any other programs. You’ve already seen it overwhelm a professional 9-dan Go player over the course of three games. As there’s no mercy rule here, the rest of the match will continue.

However, the great news is, after losing three matches, Lee Se-dol finally defeated AlphaGo in today’s match. According to Demmis Hassabis’ tweet, this time, Google’s Ai really made mistakes. he said the AI, “thought it was doing well, but got confused on move 87.”
“I’ve never been congratulated so much just because I won one game!” said Mr. Lee in the post-game press conference.
Lee Sedol is playing brilliantly! #AlphaGo thought it was doing well, but got confused on move 87. We are in trouble now…
