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...

Re: Why is the MIT License unpopular in chess programming?

Open-source code is easy to steal , no matter which license it's under, because thieves don't care about compliance anyway :D There are differences for those who wish to reuse the code legally , and there are many licenses that require attribution (the MIT one actually does too, the authors just ten...

Re: Why is the MIT License unpopular in chess programming?

Solid bump :D I can't guarantee the completeness of my lists anyway. Here's some notable open-source non-GPL code that I've learned about (or missed in 2017): Scorpio: a custom BSD-like license *, C++ FabChess : 3-clause BSD, Rust Roc : CC0, C++, a successor to Gull in TCEC with few changes Dumb : M...

Re: Question to Shut Ctf Down posters

I'm not going to read the 8 pages, sorry if I'm repeating someone else's arguments. I'm just replying to the OP. CCC is a board about a hobby, and it's an overkill to hold volunteer mods and admins to the same standard as real-life elected officials. I don't expect true democracy on internet forums ...

Re: Complicated position found

To add a bit of context, the position itself is interesting, however, it arises from a human opening variation (Two Knights: Fritz, Gruber Variation, 8. Ne4) where both sides blunder :mrgreen: [Event "Computer chess game"] [Site "PC"] [Date "2020.10.24"] [Round "?"] [White "PC"] [Black "PC"] [Result...

Re: My test for Ethereal 12.75 x64-pext-avx2_final_release

Thanks for the test! It will be funny if further testing confirms that Andrew has accidentally written a better or equal search backend for SF nets than SF itself :mrgreen:

Re: Ethereal question ... with or without NNUE is unclear!

Fwiw, the zip on RWBC is intended for CPUs that support SSE4.1 but don't support popcnt. Guenther made the binary for his hardware and kindly shared it on RWBC, which I'm grateful for because my CPU is exactly such. For CPUs that don't support SSE4.1 or do support popcnt, compile from the Ethereal 1...

Re: Final Release of Ethereal, V12.75

What's ironic is that, after opensourcing Ethereal, you don't own her future exclusively anymore. The TCEC/C3 organizers are free to enroll her derivatives, even (heavily modified) NNUEs, in later seasons against your will.
