'''iCE''',<br/>
an [[UCI]] compliant chess engine written in [[Cpp|C++]] by [[Thomas Petzke]], in late 2010 and 2011 translated from his [[Pascal]] based [[mACE]] engine, started a year earlier. Subsequent versions steadily improved, and the development of mACE and iCE over the years is documented in Thomas mACE blog <ref>[http://macechess.blogspot.de/ mACE Chess] blog by [[Thomas Petzke]]</ref>, along with elaborating on all kind of chess programming topics.
=Description=
iCE uses [[Magic Bitboards|magic bitboards]] and a [[Fail-Hard|fail-hard]] [[Principal Variation Search|PVS]] framework. Beside code cleanup, [https://en.wikipedia.org/wiki/Code_refactoring refactoring] and tuning, iCE '''2.0''' from September 2014 features [[History Heuristic|history heuristic]], [[Late Move Reductions|late move]] [[Pruning|pruning]], [[Razoring|razoring]] and [[Countermove Heuristic|counter move heuristic]]. Further, compared to iCE '''1.0''' [[Late Move Reductions|LMR]] became less aggressive, [[Lazy Evaluation|lazy evaluation]] was removed <ref>[http://macechess.blogspot.de/2014/06/not-being-lazy-anymore.html Not being lazy anymore], [http://macechess.blogspot.de/ mACE Chess], June 28, 2014</ref>, and LMR added at the [[Root|root]]. The former pure [[Pawn Hash Table|pawn hash table]] now incorporates king positions to hash additional terms <ref>[http://www.fam-petzke.de/cp_inside_ice_en.shtml Chess Programming - Inside iCE]</ref>. iCE's [[Evaluation|evaluation]] is the result of an extensive [[Automated Tuning|automated tuning]] process using the [[Genetic Programming#PBIL|PBIL]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=54545&start=1 Re: Eval tuning - any open source engines with GA or PBIL?] by [[Thomas Petzke]], [[CCC]], December 06, 2014</ref> type of [[Genetic Programming#GeneticAlgorithm|genetic algorithms]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=53741&start=4 Re: FCT1: iCE 2.0 v2240 POP x64 is still running ...] by [[Thomas Petzke]], [[CCC]], September 19, 2014</ref>.
