Many Faces of Go

Go, called "baduk" in Korean and "wei-chi" in Chinese, is a 4,000 year-old game of strategy played by more than 100 million people. Go was considered one of the Four Great Accomplishments of ancient China, one of the worthy pursuits of a lifetime - along with poetry, archery, and calligraphy. It is both an art and a mental workout - ingeniously disguised as a game. Anyone, from children of five or six to people in their nineties, can play and enjoy Go!

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 statistics on the moves to choose where to play. With very little go knowledge, this algorithm can beat any of the traditional, 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.
