const int SgHashZobrist< N >::MAX_HASH_INDEX = 1500 [static]

Hash index.

The hash index ranges from [0..MAX_HASH_INDEX-1]. For board games with black and white pieces, MAX_HASH_INDEX needs to be bigger than twice the number of points on the board. It's up to the client to map points to this range. 2 * SG_MAXPOINT, plus capture hash
