'''Ceres''', ('''C'''hess '''e'''ngine for '''res'''earch)<br/>
an [[UCI]] compliant [[:Category:Open Source|open source chess engine]] by [[David J. Elliott]], written in [[C sharp|C#]] for the [[Microsoft]] [https://en.wikipedia.org/wiki/.NET_Core .NET 5] framework, released under the [[Free Software Foundation#GPL|GPL version 3]].
Ceres provides an [[Monte-Carlo Tree Search|MCTS]] implementation with many novel algorithmic improvements and low level optimizations, searching over the [[Leela Chess Zero#Lc0|Lc0]] backends <ref>[https://www.themissingdocs.net/?p=874 Ceres] by [[Gareth Pearce|Tilps]], [https://www.themissingdocs.net/ The Missing Docs.Net], January 01, 2021</ref> with the perspective of an enormous increase in [[Playing Strength|playing strength]] over Lc0. Ceres' [[Move Generation|move generation]] code is adapted from [[Judd Niemann|Judd Niemann's]] [[Quad-Bitboards]] based [[Perft]] approach [[Juddperft]] <ref>[https://github.com/jniemann66/juddperft GitHub - jniemann66/juddperft: Chess move generation engine]</ref> <ref>[https://github.com/dje-dev/Ceres/blob/main/AUTHORS.txt Ceres/AUTHORS.txt at main · dje-dev/Ceres · GitHub]</ref>.
As posted by [[Alexander Lyashuk]] on January 01, 2021, it is possible that Ceres will co-exist in parallel to Lc0 and LCZero developers will try to back-port new ideas, or LCZero developers will abandon Lc0 completely and switch to Ceres <ref>[https://lczero.org/blog/2021/01/announcing-ceres/ Announcing Ceres] by [[Alexander Lyashuk|crem]], [[Leela Chess Zero|LCZero blog]], January 01, 2021</ref>.
