Chess engine: Blunder 8.0.0 (Windows, Mac, Linux)

Blunder - UCI chess engine Author: Christian Dean, Rating CEDR= 2569 v.8.0.0 This release is very similar in spirit to that of 5.0.0, in the sense that much of the work done has been improvement and optimization of the code base through slow, large-scale refactoring, which has brought about Elo gains, although several new strength-gaining features have been implemented. Blunder 8.0.0 is estimated to be about 50 Elo stronger than 7.6.0 at bullet time controls. It'd be impossible to list every last change, but a summary of some of the major areas will be listed below. Improvements to Blunder's move generator have been made, improving it's speed by 10-15%. Thanks in particular to Koivisto, for giving me the idea to store the hash of a position  as part of it's irreversible state, leading to a nice speed increase. Small tweaks have been made to the UCI that's made it a bit more user friendly and hopefully more straightforward to use. Magic bitboard generation code and

Chess engines: Devre 3.0

UCI chess engines: Devre Author: Γ–mer Faruk Tutkun  Rating CEDR=2908 Devre is an open-source UCI compatible chess engine written in C as a hobby project.The code is a bit badly written now but I'll try to make it cleaner and more efficent in my free time. Although Devre is an original chess engine written from scratch, I got great help from chessprogramming wiki , talkchess forum,stcokfish discord ,and some open-source C engines: Ethereal, Vice, CPW. v.3.0 Changes Fixed some bugs SEE pruning in qsearch and Alpha Beta Using SEE in move ordering Futility Pruning Switching from mailbox to bitboards New net (trained with https://github.com/OmerFarukTutkun/NNUETrainer ) Added a Linux support Embed nnue to exe ... Although 7-8 months have passed from version 2.0, I couldn't make much progress. This version is 100 elo stronger than the previous one at STC. Thanks to the testers who tested Devre, and the chess engine developers that helped me while developing my engine. Devre 3.0 down
