Abstract

Go is a difficult game for computers to master, and the best goprograms are still weaker than the average human player. Since thetraditional game playing techniques have proven inadequate, new approachesto computer go need to be studied. This paper presents a new approach tolearning to play go. The SANE (Symbiotic, Adaptive Neuro-Evolution) methodwas used to evolve networks capable of playing go on small boards with nopre-programmed go knowledge. On a 9 × 9 go board, networks that wereable to defeat a simple computer opponent were evolved within a few hundredgenerations. Most significantly, the networks exhibited several aspects ofgeneral go playing, which suggests the approach could scale up well.
