Changes

Being tempted by the success of [[Stockfish NNUE]] and attracted by how easy the method and small the code is, many engine developers have started testing and applying [[NNUE]]. For quick trials and evaluating before going into serious development, some of them borrowed and/or rewrote NNUE code and use networks from Stockfish NNUE. Most of them reported positive results, such as [[David Carteau]] with [[Orion]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=74828 Orion 0.7 : NNUE experiment] by [[David Carteau]], [[CCC]], August 19, 2020</ref>, [[Ehsan Rashid]] with [[DON]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=72613&start=320#p856640 Re: New engine releases 2020...Don NNUE 2020?] by supersharp77, [[CCC]], August 19, 2020</ref>, various [[Stockfish#Derivatives|Stockfish derivatives]] by [[Michael Byrne]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=74825 ... the last shall be first ...] by [[Michael Byrne|MikeB]], [[CCC]], 19 Aug 2020</ref>, and [[Volodymyr Shcherbyna]] with [[Igel]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=67890&start=10#p856742 Introducing Igel chess engine] by [[Volodymyr Shcherbyna]], [[CCC]], 20 Aug 2020</ref> using the ''Night Nurse'' NNUE net by [[Dietrich Kappe]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=74837 Night Nurse 0.2] by [[Dietrich Kappe]], [[CCC]], August 19, 2020</ref>. In October 2020, [[Daniel Shawul]] added NNUE support à la [[CFish]] into his [[Scorpio#Bitbases|egbbdll]] probing library of [[Scorpio]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=75400&start=22 Re: Hacking around CFish NNUE] by [[Daniel Shawul]], [[CCC]], October 15, 2020</ref> <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=75415&start=3 Re: How to scale stockfish NNUE score?] by [[Daniel Shawul]], [[CCC]], October 17, 2020</ref>, soon followed by the new promising engine [[Seer]] by [[Connor McMonigle]]with a distinct NNUE implementaion.
