CrazyStone

    Keywords: Software

Crazy Stone is a strong program by Rémi Coulom which uses Monte Carlo Tree Search and pattern learning. Crazy Stone came second in the 2007 Computer Olympiad behind MoGo. MoGo claims they were partly inspired by Crazy Stone (they are both French).

In July 2007, a [ext] match was played on KGS between Crazy Stone and KCC Igo, which Crazy Stone won 15-4. KCC Igo is considered the strongest commercial Go program.

In spring of 2011, Crazy Stone, playing as 'bonobot', briefly reached 5 dan on KGS, and maintained a 4 dan rating.

On 2007-12-02, Crazy Stone won both of the KGS tournaments and the UEC Cup in Japan, ahead of MoGo in all three events. In 2008, Crazy Stone defended its UEC Cup title, defeating Many Faces of Go. Afterwards, it defeated Kaori Aoba, Japanese 4p, in a 7-stone handicap exhibition game. This gives Crazy Stone a claim to being the strongest program in the world.

Crazy Stone is mentioned in the French public radio show [ext] Science Publique at France Culture on 2008-01-11 (there is a MP3 of the show).
