Artificial Intelligence Strength Rating for the Many Faces of Go

Go ratings for amateurs are on a scale that starts around 25 Kyu for beginners, goes to 1 kyu, then 1 dan, then 6 dan or so for the strongest players. Most people who are serious about studying the game, and have stronger players to play with, can get to 10 kyu in about a year, and 1 dan in 3 to 5 years. American (AGA), Japanese, and NNGS ratings are a little weaker than ratings in China, Taiwan, Korea, Europe, and IGS.

Go programs are hard to rate accurately, since they each have areas of strength, and other areas of weakness compared to people. So far no one has made a go program that can learn from its mistakes, so once someone has played a few games against a program, they can change the handicap against it by several stones.

The older Many Faces of Go version 11 has a 6 Kyu diploma from the Japanese Nihon-Ki-in, based on test games against rated Japanese players and some sample play against a 9-dan professional. It had a rank on the NNGS server of   8 kyu.

Many Faces verison 12 maintains a rank of around 2 Kyu on KGS, based on hundreds of games against many different players.

In 2006 and 2007 a new breakthrough algorithm for computer go (Monte Carlo Tree Search), was developed in France.  This new approach plays thousands of pseudorandom games each second, and collects statistocs on the moves to choose where to play.  With very little go knowledge, this algorithm can beat any of the tradiotional, knowledge-based, go programs.  However the style of this new algorithm is strange.  Many Faces of Go, version 12 is the only program to combine the new search algorithm with the go knowledge from version 11.  This led to over 5 stones increase in playing strength.  At the 2008 ICGA world championship, the pure Monte Carlo programs beat all of the traditional programs, and Many Faces of Go version 12 beat all of the Monte Carlo and traditional programs.
