Everything about Transposition table

Cache of previously seen positions, and associated evaluations in a game tree

A transposition table is a cache of previously seen positions, and associated evaluations, in a game tree generated by a computer game playing program. If a position reoccurs via a different sequence of moves, the value of the position is retrieved from the table, avoiding re-searching the game tree below that position. Transposition tables are primarily useful in perfect-information games. The usage of transposition tables is essentially memoization applied to the tree search and is a form of dynamic programming.
