change NNUE file ?

[tissatussa]

I can compile your source on Xubuntu 22.04 and i wonder : can i change the NN file and compile ? Will your search / eval logic work with any another NN ? (being the same format)

[bitArtisan1]

Yes, it should work with another .nnue file, make sure to change the file name to your new .nnue in my init.cpp file.

@bitArtisan1 tnx, i will experiment with different compiles .. in README you state the "NNUE Evaluation" is "Features=HalfKP(Friend)[41024->256x2],Network=AffineTransform1<-32" which means the good-old Stockfish 20 Mb ones .. lots of them exist, i once found "red neuronal", from some "Fischermann" or so, he trained many NN and maybe still does .. is your NNUE file unique ?

[bitArtisan1]

No problem! No, it's not unique—it's a pre-trained network from the Stockfish repositories, and I haven't made any modifications to it. You can find it in the Stockfish NNUE database here.
Good luck with your experiments!

@bitArtisan1 yes, that SF db is well-known .. in the meantime i compiled Wize with several such 20 Mb NNs and let those engines play against eachother and also other NN-based engines of equal strength or having a (own) small NN (say upto 5 Mb) and see how they perform .. i used this position :

1. e4 c6 2. d4 d6!

Black plays the Caro-Kann Defense and should do 2...d5 but i'm experimenting with this d6-setup in my own games. SF often plays d6-d5! soon, though wasting a tempo .. pawns can not go back ! White should be able to win such game, but with many pieces on the board it's all about good moves!

soon i will post the game list here - have to prepare - but here's one nice game : your default NN wins with Black against Wize-with-Mida-NN (see https://github.com/GiacomoPorpiglia/Mida ) .. but Mida itself beats default-Wize, so i keep wondering what happens to the strength of any NN, all trained differently, in your Wize ?
