=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>.
