<br />
'''Ginkgo''',<br/><br />
an [[UCI]] compliant private chess engine written by [[Frank Schneider]] in [[Cpp|C++]], the development started in fall 2014 after further improvements of Frank's earlier [[0x88]] engine [[Anaconda]] were diminishing. Ginkgo was written from scratch using [[Bitboards|bitboards]] as primary board representation, in particular [[Magic Bitboards#Fancy|fancy magic bitboards]] to determine [[Sliding Piece Attacks|sliding piece attacks]]. The [[Parallel Search|parallel]] [[Thread|multi-threaded]] [[Search|search]] performs [[Principal Variation Search|PVS]] [[Alpha-Beta|alpha-beta]] with a [[Shared Hash Table|shared]] [[Transposition Table|transposition table]] inside an [[Iterative Deepening|iterative deepening]] framework with [[Aspiration Windows|aspiration windows]], [[Null Move Pruning|null move pruning]], [[Late Move Reductions|late move reductions]], and various [[Extensions|extensions]], but no [[Singular Extensions|singular]]. The [[Automated Tuning|automatically tuned]] [[Evaluation|evaluation]] features [[Material|material]], [[Mobility|mobility]], [[Pawn Structure|pawn structure]] and [[King Safety|king safety]]. <br />
<br />
=Tournament Play=<br />
Ginkgo had its tournament debut at the [[WCCC 2015]] and [[WCSC 2015]] in [[Leiden University|Leiden]], and was close winning the latter, finally losing from [[Shredder]] in the blitz playoff. At the [[WCCC 2016]] in Leiden again, Ginkgo was incorporated in the [[GridGinkgo]] [https://en.wikipedia.org/wiki/Computer_cluster cluster] chess program by [[Kai Himstedt]] et al..<br />
