'''Black Marlin''',<br/>
an [[UCI]] compatible [[:Category:Open Source|open source chess engine]] by [[Doruk Sekercioglu]], written in [[Rust]],
licensed under the [[Free Software Foundation#GPL|GPL v3.0]], and first released in October 2021 <ref>[https://github.com/dsekercioglu/blackmarlin/releases/tag/1.0 Release 1.0 · dsekercioglu/blackmarlin · GitHub]</ref>.
[[Bitboards|Bitboard]] based [[Move Generation|move generation]] is done using the [[Rust]] [[Rust#cozy_chess|cozy_chess]] library by [[Analog Hors]].
The engine features [[NNUE]] [[Evaluation|evaluation]], and comes with ''Marlinflow'', a Neural Network training repository for the engine <ref>[https://github.com/dsekercioglu/marlinflow GitHub - dsekercioglu/marlinflow: Neural Network training repository for the Black Marlin chess engine]</ref>.
For optimal NNUE inference on various [[X86-64]] systems using their most advanced [[SIMD and SWAR Techniques|SIMD instruction]] sets,
[[Windows]] binaries are available supporting [[SSSE3]], [[SSE4#SSE4.2|SSE4.2]], [[AVX2]] and [[AVX-512]].
Black Marlin '''4.0''', released in January 2022, improved due to a larger network, more aggressive [[Pruning|pruning]] and better [[Move Ordering|move ordering]]
