CHEOPS (CHEss OPponent Simulator) is a fully-functional 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 is written in ANSI C++ and as such should compile on any system with a conforming C++ compiler. A standard configure script is provided for Unix-like systems.
CHEOPS is Free Software. It can be freely used, modified, and distributed under the terms of the GNU General Public Licence.
