Re: NNUE

Hi Sidiki, What Eman does looks pretty much like a technique called 'root-learning', this is something that has already been pioneered back in 1959 by Samuel's checkers program. Alpha-Zero makes use of a 'policy network' which is a different technique although the net effect could look similar. The...

Re: Unofficial World Championship Of Computer Programs In International Draughts 2021

Hi all (again :D ) Once again, thanks to Krzysztof and all the programmers that maked this happen.

But here, no program are ranked, so SB, itsn't so n...

Re: Unofficial World Championship Of Computer Programs In International Draughts 2021

Hi all, I see about what your aren't agree with each other: One part write about strenght difference, another part of won games linked to won points. It's like a program that have an elo of 3000 points that draw against another one with 2200 elo must lose some points and the weaker must win points. ...

Interesting to read old posts (10 years ago).
Especially when we see the progress being made in evaluation functions (and alike).

Re: NNUE

By clipping the network weights and biases after each batch between -0.99 and +0.99 and retraining the network (which took about 1 day) the network quality with int8 quantization improved quite a bit.
