'''QuTeChess''',<br/>
an experimental, [[UCI]] compatible [[:Category:Open Source|open source chess engine]] under the [[Free Software Foundation#GPL|GNU General Public License]] written by [[Aleš Zamuda]], available from a [https://en.wikipedia.org/wiki/SourceForge SourceForge] [https://en.wikipedia.org/wiki/Apache_Subversion SVN] [https://en.wikipedia.org/wiki/Codebase repository] <ref>[https://sourceforge.net/projects/qutechess/ QuTeChess | Free Science & Engineering software downloads at SourceForge.net]</ref>.
As its name suggests, QuTeChess is written in [[Cpp|C++]] using the [https://en.wikipedia.org/wiki/Qt_%28framework%29 Qt4.7] cross-platform application framework (using QTime, QThread).
It reflects the author's dealings with Qt to implement UCI and [[CLI]] along with [[Thread|threads]] to start an interruptible [[Search|search]].
=Description=
QuTeChess is quasi [[Bitboards|bitboard]] based using [[Tinker|Tinker's]] [[Sliding Piece Attacks#Tinker's Approach|approach]] in [[Move Generation|move generation]] of [[Sliding Pieces|sliding pieces]].
Based on the [[Bitboard Serialization|serialization]] of attacks on the otherwise empty board, it tests for [[Pseudo-Legal Move|pseudo legality]] by looking whether squares [[Square Attacked By#InBetween|between]] [[Origin Square|origin]] and [[Target Square|target]] are empty.
Its [[Search|search]] is a plain [[Alpha-Beta|alpha-beta]] without [[Transposition Table|transposition table]] inside an [[Iterative Deepening|iterative deepening]] loop.
The availability of ''changegenes.cpp'' suggests QuTeChess'
[[Point Value|piece values]] and a few random [[Evaluation|evaluation]] features could be [[Automated Tuning|tuned]] by an [[Genetic Programming#EvolutionaryComputation|evolutionary computation]] approach of [https://en.wikipedia.org/wiki/Differential_evolution differential evolution] <ref>* [[Borko Bošković]], [[Sašo Greiner]], [[Janez Brest]], [[Aleš Zamuda]], [[Viljem Žumer]] ('''2008''').
