Hi,
Tucano 10 NN has been released. It has a couple of changes but the main change is the introduction of neural network evaluation.
I used tucano hand crafted evaluation to generate about 1.5B positions, and used the nodchip trainer to generate the nn weights.
For NN probing I'm using Daniel Shawn NNUE probe library.
The improvement is about 200 elo over version 9.00. It is recommended to use AVX2 whenever possible. I also provided the "_OLD" version that does not make use of "intrinsics", meaning slower code.
It is available for download from my github page, but you can download the release 10.00 which contains binaries for different architectures.
--> https://github.com/alcides-schulz/Tucan ... /tag/10.00
Note that are binaries for windows and Linux (Centos). The network weights file is tucano_nn01.bin. Tucano will try to load this file by default if it is the same folder as the binary file, otherwise you can specify the UCI parameter EvalFile. More information in the README file.
Please let me know any issues.
For future plans, I'm planning to continue the work on NN, Maybe can create a probing code or create my own trainer. I'm already doing some research on this.
Alcides.
