The Muses: Clio, Euterpe, and Thalia [1]

a Chess Engine Communication Protocol and UCI compliant chess engine by Martin Fierz, first released in August 2004 [2]. Muse is written in C, using bitboards and is about 13'000 lines of code. It applies most of the usual stuff [3], such as alpha-beta scout-style search with transposition table, move ordering with killer heuristic and history heuristic, adaptive null move pruning, check and recapture extensions. Quiescence search is enhanced by static exchange evaluation to order and prune captures, and further, the evaluation utilizes a pawn hash table. After an abstinence of 12 years from computer chess, Martin released the improved Muse 0.95 in April 2016 [4], using Pradu Kannan's magic move generator [5] [6].
