'''Wasp''',<br/>
[[John Stanback|John Stanback's]] new [[UCI]] compliant chess engine and complete rewrite of [[Zarkov]], first released short after [https://en.wikipedia.org/wiki/June_solstice June solstice] 2016, announced <ref>[http://www.talkchess.com/forum/viewtopic.php?t=60550 Wasp 1.01 x64 by John Stanback released ...] by [[Frank Quisinsky]], [[CCC]], June 22, 2016</ref> and hosted by [[Frank Quisinsky]] <ref>[http://www.amateurschach.de/main/_wasp.htm Frank's Chess Page, Wasp by John Stanback], June 22, 2016</ref>. As a [[Bitboards|bitboard]] engine, Wasp is compiled for modern [[x86-64|64 bit CPU's]] with [[Population Count|popcnt]] and [[BitScan|bitscan]] instructions. Wasp '''2.00''', released in April 2017, is able to use multiple [[Thread|threads]] performing a [[Lazy SMP]] search <ref>[http://www.talkchess.com/forum/viewtopic.php?t=63783 Wasp 2.00 by John Stanback ... with Lazy SMP!] by [[Frank Quisinsky]], [[CCC]], April 21, 2017</ref>.
In 2020, John Stanback played with tiny [[Neural Networks|neural networks]] to learn how to [[Neural Networks#Backpropagation|backpropagate]] errors using Wasp's [[Evaluation|evaluation]] as the target, and then rewrote Wasp's evaluation function with fast [[Automated Tuning|tuning]] in mind, quite similar to the tiny NN approach <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=75794&start=4 Re: Wasp NN] by [[John Stanback]], [[CCC]], November 14, 2020</ref>. Along with Wasp '''5.00''', released in November 2021, the evaluation function emerged to an [[NNUE]] with 1830 inputs, 192 neurons in the first hidden layer, 16 neurons in the second hidden layer, and two neurons in the third hidden layer. It was trained using positions from games between Wasp and other engines of roughly similar strength <ref>[https://www.talkchess.com/forum3/viewtopic.php?f=2&t=78687 Wasp 5.00 released] by [[John Stanback]], [[CCC]], November 18, 2021</ref>.
