=Description=

Pedone has a compact [[Quad-Bitboards|quad-bitboard]] board representation <ref>[https://sites.google.com/site/pedonechess/programming-articles/quadbitboard Pedone Chess Engine - QuadBitboard]</ref> , suited for a [[Copy-Make|copy-make]] approach, and further applies [[Magic Bitboards|magic bitboards]] for [[Sliding Piece Attacks|sliding piece attacks]] and [[Move Generation|move generation]]. Its search is [[Alpha-Beta|PVS]] with [[Transposition Table|transposition table]], [[Internal Iterative Deepening|IID]] and [[Quiescence Search|quiescence search]] inside an [[Iterative Deepening|iterative deepening]] framework. The [[Evaluation|evaluation]] function was [[Automated Tuning|tuned]] with a similar approach to the [[Texel's Tuning Method]] <ref>[https://sites.google.com/site/pedonechess/programming-articles/evaluation-tuning Pedobe Chess Engine - Evaluation Tuning]</ref> until version 1.0. Some evaluation bonuses of versions 1.3 and 1.4 were tuned with [[Temporal Difference Learning|TD Learning]]. Since '''1.0''', released in December 2014, Pedone performs a [[Parallel Search|parallel search]] using multiple [[Thread|threads]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=54640 Pedone 1.0] by [[Fabio Gobbato]], [[CCC]], December 14, 2014</ref> , with '''1.4''' in April 2016, dubbed [[Lazy SMP]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=59732 Pedone 1.4] by [[Fabio Gobbato]], [[CCC]], April 03, 2016</ref>. The further improved Pedone '''1.6''' released in June 2017 can use up to 128 threads and comes with an executable for [[Android]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=64241 New release Pedone 1.6] by [[Fabio Gobbato]], [[CCC]], June 10, 2017</ref>. Since 2018, Pedone '''1.8''' is able to play [[Chess960]].
