The+Turk

an experimental chess program developed in the mid 90s by two students of the University of Alberta and members of the //Games research group//, Yngvi Björnsson and Andreas Junghanns, which competed the WMCCC 1996 in [|Jakarta]. It uses NegaScout and also includes most search enhancement found in contemporary chess programs, such as extensions, quiescence search, and transposition table. Move ordering considers captures in MVV-LVA order, and the history heuristic is used to sort the remaining moves. The best move previously found in a position is stored in the transposition table and searched first where applicable. The Turk was test-bed of various pruning techniques such as Uncertainty Cut-Offs and Multi-Cut. || toc =Namesake=
