Go grandmaster Lee Se-Dol retires saying artificial intelligence cannot be defeated

Go grandmaster Lee Se-Dol retires saying artificial intelligence cannot be defeated

AlphaGo won four of its five matches against Se-dol in March 2016.

According to South Korea's Yonhap News agency, 18-time world Go champion Lee Se-dol said he made a decision to retire because after he realized that he was "not at the top even if I become number one".

"With the debut of the AI in the game Go, I realized that I was not at the top even if I become number one through the frantic efforts", Lee told Yonhap.

While this may seem like yet another case of someone bleating on about the rise of the robots and being sour about AI smarts, Lee Se-dol was actually the only player to defeat Google's DeepMind AlphaGo, an AI trained specifically to pwn human players at Go.

But he attributed his AlphaGo win to a "bug" in the program's response to his "tricky" play.

"On behalf of the whole AlphaGo team at DeepMind, I'd like to congratulate Lee Se-dol for his legendary decade at the top of the game, and wish him the very best for the future", Hassabis said.

Despite the game's simple rules, which see two players take turns placing white or black stones on a square board to try and capture the most territory, complex strategies were needed to in order attain victory. AlphaGo shocked the world with its so-called "move 37", which human consultants initially thought was a mistake, however which proved decisive in recreation two.

"My white 78 was not a move that should be countered straightforwardly", he said.

The South Korean Go master gained global fame in 2016 as the only human to defeat DeepMind's AlphaGo computer program.

"Even with a two-stone benefit, I really feel like I'll lose the primary recreation to HanDol", Lee instructed Yonhap. But when it loses, it loses in a unusual way.

Lee Se-dol is considered to be one of the greatest Go players of the modern era.

To commemorate his retirement, Lee plans to face off against one last AI Go rival next month: HanDol, developed by South Korea's NHN Entertainment Corp., has already defeated the country's five top players. He turned pro at age 10.

The dominance of artificial intelligence in competitive strategy games has led one of South Korea's top Go players to retire. "People from Google's DeepMind Technologies looked very confident from the beginning".
