'''Darmenios''',<br/>
a [[WinBoard]] compliant chess engine by [[Dariusz Czechowski]], written in [[Cpp|C++]], first released in January 2010.
Darmenios performs [[Bitboards|bitboard-based]] [[Move Generation#Legal|legal move generation]], [[Alpha-Beta|alpha-beta search]] with [[Null Move Pruning|null-move pruning]], [[Quiescence Search|quiescence search]], [[History Heuristic|history based]] [[Move Ordering|move ordering]], and uses a [[Transposition Table|transposition table]] with a special replacement algorithm.
In 2010, the rudimentary [[Evaluation|evaluation]] considered [[Mobility|mobility]], [[Piece-Square Tables|piece-square tables]] and [[Passed Pawn|passed pawns]] <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=611 Darmenios' ICGA Tournaments]</ref>, and apparently has improved since then.
=Tournament Play=
Darmenios played the [[WCCC 2010]] and [[WCSC 2010]] in [https://en.wikipedia.org/wiki/Kanazawa,_Ishikawa Kanazawa]. At the [[Polish Computer Chess Championship]] Darmenios demonstrated huge progress in two years after its debut at [[PCCC 2009]] with 0/6, the [[PCCC 2010]] already third with 3½/6, and winning the [[PCCC 2011]] with 5/6.
At the [[WCRCC 2011]], the Fifth Annual ACCA World Computer Rapid Chess Championship, Darmenios became sixth with 5½/10.
