One of the world’s best Go (high) grandmasters who announced his retirement last month, Lee Sedol, won the artificial intelligence (AI) program for the second time in a farewell event.

On December 18th, at the Body Friend Dogok Tower in Gangnam-gu, Seoul, South Korea’s NHN Communication Co., Ltd. developed Handol and won the first of the three scheduled matches.

In 2016, players acquired AlphaGo, an AI program developed by DeepMind Technologies, later as a series of five games. After losing the first three games, he said, “I believe today’s loss is not human loss, but this Sedol’s loss.”

However, Lee Myung-bak defeated Alpha Go in their fourth match on March 13, 2016.

As the world’s first Pro Go player to beat the AI ​​program, he decided to pursue a career spanning 24 to 4 months in a match against Handol.

“I wanted to show the best out of predicting the gap between humans and AI, not outcomes,” he said, saying that he had two advantages and won 92 moves. The last time you play in the rest of the game, you will see I do my best as a human. ”

HanDol, considered more advanced than the 2016 version of AlphaDoc, was developed based on data accumulated since 1999 by NHN running the PC game Hangame Go. In January of this year, the program defeated Korea’s top five professional players, and in August it took third place at the China Securities Cup World AI Go Open.
