Rodent NNUE (works with the old SF networks)

[PK]

http://www.pkoziol.cal24.pl/rodent/RodentNNUE.7z

This is an unofficial release of Rodent IV with NNUE capabilities. NNUE code has been lifted from Toga NNUE. It uses old (smaller) Stockfish networks and mixes their score with handcrafted Rodent eval. Implementation is not optimal, because NNUE score is calculated from scratch, but still gains about 320 Elo points over handcrafted eval, assuming that default parameters are used.

Now for the best thing. Since it uses NNUE and classic eval simultaneously, and good old personality system is still in place, You can effectively play against rocket-fuelled version of Your favourite opponent.

Download package is quite heavy, because it includes multiple opening books and NNUE file from Stockfish.

This is a one-shot upload, any improvements are unlikely.

There is an UCI option to find a file. Does it fail too?

Hi Pawel,

when i click directly on Rodent nnue program an error is displayed but if i use a GUI all is correct. So i presume that is a minor bug with no importance.

But i'm puzzled, NNUE and manual evaluation are supposed incompatible at same time?

Best regards

Why should they be? They're two functions, you can implement both and combine their values, as Rodent seems to do, looking at the UCI options.

You can significantly reduce the download size by removing the seemingly unnecessary PGO data in the sources/.vs folder.

It does not appear the NNUE file is loading when played in Banksia GUI. I have the NNUE file in the same folder as the exe.

The below us from the engine log file.
7.17:19:22 Rodent NNUE 1.0> Loading NNUE : nn-62ef826d1a6d.nnue
7.17:19:22 Rodent NNUE 1.0> NNUE file not found!

Hi Pawel,

i discovered the mystery of nnue's ghost file.

If you copy the Rodent nnue.exe into the "exe" folder and launch the program directly, you got a message "NNUE loaded !".

So the path of nnue file is hardcoded.

Hi Pawel

I have one small request

Can you please increase number of Threads to 512? I have AMD Threadripper 3990X 64 cores... Number of Threads I can use is 128. If posible can you please increase the number of Threads for Rodent ? As things are right now, I can only use 48 Threads for Rodent as that is the Default Threads value...
Best Wishes
Damir
