Wasp [1]

Wasp,
John Stanback's new UCI compliant chess engine and complete rewrite of Zarkov, first released short after June solstice 2016, announced [2] and hosted by Frank Quisinsky [3]. As a bitboard engine, Wasp is compiled for modern 64 bit CPU's with popcnt and bitscan instructions. Wasp 2.00, released in April 2017, is able to use multiple threads performing a Lazy SMP search [4]. In 2020, John Stanback played with tiny neural networks to learn how to backpropagate errors using Wasp's evaluation as the target, and then rewrote Wasp's evaluation function with fast tuning in mind, quite similar to the tiny NN approach [5]. 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 [6].

  1. ↑ Vespula is a small genus of social wasps, widely distributed in the Northern Hemisphere. Along with members of their sister genus Dolichovespula, they are collectively known by the common name yellow jackets (or yellow-jackets) in North America. Vespula species have a shorter malar space and a more pronounced tendency to nest underground, but are otherwise nearly indistinguishable from Dolichovespula.
