Crazy Stone is a Go playing engine, developed by Rémi Coulom. It is one of the first computer Go programs to utilize a modern variant of the Monte Carlo Tree Search.[1]

History
Coulom began writing Crazy Stone in July 2005, and at the outset incorporated the Monte Carlo algorithm in its design. Early versions were initially available to download as freeware from his website, albeit no longer.[2] Pattern recognition and searching was added in 2006, and later that year Crazy Stone took part in its first tournament, winning a gold medal in the 9x9 competition at the 11th Computer Olympiad.[2] Coulom subsequently entered the program into the 12th Computer Olympiad the following year, winning bronze in the 9x9 and silver in the 19x19 competitions.
However, Crazy Stone's most significant accomplishment was to defeat Kaori Aoba, a professional Japanese 4 dan, in an 8-stone handicap match in 2008. In doing so, the engine became the first to officially defeat an active professional in Japan with a handicap of less than nine stones. Three months later, on 12 December 2008, Crazy Stone defeated Aoba again in a 7-stone match.[3]
