Home * Evaluation * Evaluation Hash Table
An Evaluation Hash Table may be used in a similar fashion as the transposition table, that is using Zobrist- or BCH-hashing, to cache various computational expensive positional evaluation scores and flags. Despite the fact that the transposition table entries may contain evaluation scores as well, a tighter, dedicated evaluation hash table with its own replacement policy may gain a considerable amount of additional hits.
