Minic
Minic,
a Chess Engine Communication Protocol compliant open source chess engine by Vivien Clauzon, initially squashed inside a single C++ source file licensed under the GPL v3.0.
As a weekend project, it started as 2000 lines of code mailbox approach using PVS with TT, NMP, LMP and eval based on psts, and evolved to a bitboard engine using HQ, lazy SMP, and Texel tuning to optimize its tapered eval [1].
MinicNNUE
With the advent of NNUE in summer 2020, Vivien Clauzon released Minic 2.47 aka MinicNNUE with Stockfish's NNUE network architecture and weight files, yielding in a strength increase of about 200 Elo versus Minic with standard evaluation, but the demand that this NNUE version should not replace Minic in official rating lists [2]. Minic 2.50 incorporates the training code from Nodchip's Stockfish repository, so MinicNNUE is now able to produce weight files by its own play [3].
