Chess engine: Black Marlin 5.0 NNUE

-



Black Marlin - UCI engine, Author: Doruk SEKERCIOGLU
Rating CEDR=2983

Black Marlin 5.0 is noticeably more optimized than 4.0, comes with various improvements to the search function and uses the HalfKP feature set for NNUE evaluation. The network has been trained on 820M positions which is composed of the dataset used to train 4.0 neural networks and a newly generated one. The neural network is embedded in the executable, so no additional work is required.
In self play, Black Marlin 5.0 is ~125 Elo stronger than Black Marlin 4.0 at short time controls (8+0.08).

The binaries require the instructions in their names (e.g. blackmarlin-popcnt-avx2.exe will require popcnt and avx2 instructions).

Binaries Ordered by Runtime Performance:

AVX512F + POPCNT
AVX2 + POPCNT
SSE4.2 + POPCNT
SSSE3 + POPCNT
POPCNT

The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it. As you can see in the second screenshot, the program interface hasn't changed much; only the icons are different (we've been using Fritz 17 until now). It looks nice, but it's no major revolution. The next two screenshots show engine management and the installation of the UCI chess engine (here, Cataphract 1.1). As you can see, there are no changes. Screenshot no. 5 shows the analysis of some position by Fritz 20 engines. The changes are minimal - it is still very legible. Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
