Re: Your motivation for writing a chess engine?

I've just had a weird thought about the aspect of chess programming that's less often talked about. Namely, writing an engine is like a lightweight version of raising a child :lol: It usually takes <8 months to get the first version that compiles, and <<18 years for the training to converge. Writing...

Re: Stockfish licensing question

First, we need a clarification on what exactly was meant by use Stockfish 11 from github to do the position evaluation As purechess has correctly hinted, if the proprietary code interacts with the (possibly modified) SF executable through the command line or a pipe in a standard protocol like unmodi...

Re: Stockfish licensing question

Those sites are using the SaaS loophole. Generally, that way to use software covered by GPL is risky because placing any code on the client side may count as distribution. However, it's fairly safe in the chess case because the authors are unlikely to bother to sue the offenders. Anyway, use Arasan ...

About NNUE. Although I'm against reinventing the wheel. I might come up w/ smt more original. The problem is. I can't really take a -300 Elo hit.
One doesn't divert interest from the giants by mirroring them. Take the hit for a chance to stand up stronger.

Re: Is Talkchess still the centre of computer chess programming?

There have been discussions here on what could be better NN topologies and better search algorithms. But the Leela programmers made it very clear they were not interested in that, because it was not what the AlphaZero paper said, and they wanted to make an exact replica of AlphaZero. This is no lon...

Re: Your motivation for writing a chess engine?

Chess has been a toy game for AI researchers. DeepMind conquered it before throwing A0 on serious, high-stakes problems such as protein modeling. Among the next breakthroughs will probably be deep learning on graphs, for which tactical board games with heterogeneous long-range pieces like chess and ...

NO NN or NNUE Support ?
No, not yet. If you want it, you can submit a pull request ;-).
Now that you've written the NNUE reader (thank you!), can we expect good news on this soon? :)

Re: speaking of GPL

I've accidentally discovered that, 9 hours ago, Martin made 11 commits to the nnue-trainer repo and, in particular, replaced the dataloader with a new one, so the repo seems free from GPLed code and thus legitimately under MIT now. Thanks a lot to Martin!

Re: LC0 + Stockfish = love?

It would be surprising if there were no love between the Gary Linscott engines that were both using Sergio Vieri nets :P

Re: NNUE vs New Engines Swiss...No Changes?

2-3 games per engine are extremely small samples :D Hundreds of games are needed per engine for statistically significant conclusions. Let's take the SF, Nemorino, and Igel rating progress on FGRL 60-minute (the complete list as of Nov 5) as examples (the numbers in parentheses are standard deviatio...
