Re: NNUE

Krzysztof, i understand the situation. Basically when the engine thinks, you should not be able to move the pieces (in your case the black pieces). So what is your preference? I can change the GUI that the input during engine thinking/search is not possible, or that input is possible, in which case ...

Re: NNUE

Krzystof, question when exactly do you get the Error:Illegal Engine Move Message!

If you can explain me the specific situation , i might be able to see the same here, and start solving it.

I will think about pondering, and put some info in the grey box....

Re: NNUE

And if you can wait even longer, most likely the ZEN 4 based Threadripper will be introduced in 2022, and according rumours it will contain avx512.

Re: NNUE

Krzysztof,

i will make a detection mechanism in Damage 16.0, so it will use avx2 or avx-512 when available.

Re: NNUE

How reasonable would it be to train a nnue-policy-network to use for move-ordering ? Has anyone already tried that ? So far as I know no-one has tried this for draughts (or checkers).

To test scan nnue in hub mode, add hub on the target line (rightclick the shortcut on the desktop), see screenshot.
