CHEOPS (CHEss OPponent Simulator) is a fully-functional AI chess program capable of human vs. human, human vs. computer, and computer vs. computer play. It uses a 64-square linear array board
representation. The game tree search is
alpha-beta, and the static evaluation function
considers material, mobility, and motif features. CHEOPS comes with extensive documentation on the program internals, aimed at students or programmers wishing to understand or extend the system.
