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.
The latest version of CHEOPS is 1.3, released on 2016-12-27. A list of changes from previous versions can be found in the change log.
You can download source packages for the current and previous releases on GitHub or nothingisreal.com. You can also browse, download, or clone the development version on GitHub.
