GENERATION OF PATTERNS WITH EXTERNAL CONDITIONS FOR THE GAME OF GO

Pattern databases are constructed to improve the search process in game-playing programs. We have generated pattern databases for the game of Go. The generated patterns are associated to conditions that are external to the pattern. This method enables a pattern to cover much more positions, but it leads to new problems for pattern generation too. We explain how we managed to solve these problems and provide experimental results. Moreover, we believe that patterns associated to external conditions can be useful in other games.
