Detailed Description

template<typename KeyType, size_t NumConfKeys>
class boardstate::TranspositionTable< KeyType, NumConfKeys >

Stores and manages key-value pairs consisting of a board_state (from a boardstate::ZobristComponent) and results of Minimax calculations performed by boardstate::MinimaxMoveEvaluator.

Provides read/write access to moveselection::MinimaxMoveEvaluator via a boardstate::ZobristCoordinator.
