'''Cheops''', (CHEOPS, CHEss OPponent Simulator, Χέοψ)<br/>
a didactic [[:Category:Open Source|open source chess engine]] by [[Tristan Miller]], written in [[Cpp|C++]], licensed under the [[Free Software Foundation#GPL|GNU GPL]], and first released in 1999, version 1.0 in 2003, and version 1.2 in February 2015 <ref>[https://groups.google.com/d/msg/rec.games.chess.computer/PfEqoxFZ-vI/K_66ofncsRQJ CHEOPS 1.2 -- An AI chess engine -- released on 2015-02-01] by [[Tristan Miller]], [[Computer Chess Forums|rgcc]], February 03, 2015</ref>.
The program uses a [[CLI|command line interface]] to interact with the user, and prints simple [[Graphics Programming#ASCIIDiagrams|text diagrams]] to display the current [[Chess Position|position]] during [[Chess Game|game play]]. [[Moves]] are printed and [[Entering Moves|entered]] in [[Algebraic Chess Notation#PureCoordinateNotation|pure algebraic coordinate notation]].
[[Daniel José Queraltó]] has produced a build of CHEOPS 1.2 for [[Microsoft]] [[Windows]]. [[Michael Yee]] has produced an [[UCI]] compliant build of CHEOPS 1.1 <ref>[https://logological.org/cheops CHEOPS | Tristan Miller]</ref>.
=Description=
Cheops uses a [[8x8 Board|64-square]] linear [[Array|array]] [[Board Representation|board representation]] and performs a [[Move Generation#Legal|legal move generation]] [https://en.wikipedia.org/wiki/Anti-pattern anti-pattern] by looking for [[Origin Square|from-squares]] of own [[Pieces|pieces]] traversing the board in [https://en.wikipedia.org/wiki/Spiral spiral] order from center to the h1-edge, keeping, returning and splicing [https://en.wikipedia.org/wiki/Sequence_container_%28C%2B%2B%29#List std::list] as local [[Move List|move list]] variables on the stack.
The tree [[Search|search]] is fixed [[Depth|depth]] [[Alpha-Beta|alpha–beta]] without [[Quiescence Search|quiescence search]]. The static [[Evaluation Function|evaluation function]] considers [[Material|material]], [[Mobility|mobility]], [[Center Distance|center proximity]], [[King Safety#KingTropism|king piece tropism]], and a few [[Pawn Structure|pawn structure terms]] such as [[Isolated Pawn|isolated]], [[Doubled Pawn|doubled]] and [[Backward Pawn|backward pawns]] <ref>[https://logological.org/cheops CHEOPS | Tristan Miller]</ref>.
