Background and Impact

Since 2009, the IEEE Computational Intelligence Society (CIS) has funded human vs. computer Go competitions in flagship conferences, including FUZZ-IEEE 2009, IEEE WCCI 2010, IEEE SSCI 2011, FUZZ-IEEE 2011, IEEE WCCI 2012, FUZZ-IEEE 2013, FUZZ-IEEE 2015, IEEE CIG 2015, and IEEE WCCI 2016. The technique of Monte Carlo Tree Search (MCTS) has revolutionized the field of computer game-playing for the past decade. However, the progress of computer Go has been bounded to four handicaps against with top professional Go players since about 2012-2015. Google DeepMind introduced a new approach to computer Go that combines Monte Carlo tree search (MCTS) with deep learning including value and policy networks in Oct. 2015. Honored with a 9-Dan professional award by Korea Baduk Association, AlphaGo made a great milestone for the development on the computer Go and artificial intelligence (AI) in Mar. 2016. In addition, Google Master won the 60 games on the Internet in Jan. 2017.

Besides, the FUZZ-IEEE 2009: Panel, Invited Sessions, and Human vs. Computer Go Competition was held at the 2009 International Conference on Fuzzy Systems in Aug. 2009. This event was the first human vs. computer Go competition hosted by the IEEE Computational Intelligence Society (CIS) at the IEEE CIS flag conference. In 2010, MoGo and Many Faces of Go achieved wins against strong amateur players on 13x13 with only two handicap stones. In April 2011, MoGoTW broke a new world record by winning the first 13x13 game against the 5 Dan professional Go player with handicap 3 and reversed komi of 3.5. It also won 3 out of 4 games of Blind Go in 9x9. In June 2011, in the three-day completion held at FUZZ-IEEE 2011, there are four programs, including MoGoTW, Many Faces of Go, Fuego, and Zen, invited to join this competition, and more than ten invited professional Go players accept the challenge, including Chun-Hsun Chou (9P), Ping-Chiang Chou (5P), Joanne Missingham (5P), and Kai-Hsin Chang (4P). The computer Go program Zen from Japan won each competition even playing 19x19 game with Chun-Hsun Chou (9P) with handicap 6, showing that the level of computer Go programs in 19x19 game is estimated at 4D. In addition, MoGoTW also won all of twenty 7x7 games under a specific komi, that is, setting komi 9.5 and 8.5 as MoGoTW is White and Black, respectively, suggesting that the perfect play is a draw with komi 9. MoGoTW with the adaptive learning ability was first played with the amateur Go players from kyu level to dan level in Taiwan, on May 6 and May 27, 2012. Estimating the level of an opponent is useful for choosing the right strength of an opponent and for attributing relevant ranks to players. We estimate the relation between the strength of a player and the number of simulations needed for a MCTS to have the same strength. In addition, we also play against many players in the same time, and try to estimate their strength. In Oct. 2015, AlphaGo and Fan Hui (2P) competed in a formal five-game match and AlphaGo won the match 5 games to 0. In Mar. 2016, AlphaGo won four of the five 19×19 games without handicap against Lee Sedol (9P). And, commentators noted that AlphaGo played many unprecedented, creative, and even beautiful moves. Zen, Facebook Darkforest, and Crazy Stone got the first three places in the 9th Computer Go UEC Cup.

Facebook Darkforest Go engine powered by deep learning has been developed mainly by Dr. Yuandong Tian from Facebook AI Research (FAIR) since May 2015 and was open to the public in 2016. Darkforest Go has a stable rank of 5D on the KGS server and pure policy network achieves a stable rank of 3D on KGS. It received the third place and second place in the KGS Go Tournament 2016 and in the ninth UEC Cup Computer 2016, respectively. The IEEE WCCI 2016 in Canada and ICIRA 2016 in Japan also invited Darkforest Go to join the demo games with top professional Go players.
