Automated Engine Analysis: AI or Human, Similarity To Stockfish

Post by chrisw »

Github sources scanned and compared. Authorship (AI or use of AI) and Similarity to Stockfish. As many engines as could be found, CCRL Top 50 and any new engine announced here on talkchess in 2016

Cool, I hope it helps you to identify new engines that are just basically written by AI. Personally, I'ld exclude them from the main lists, but if you really want to test them, maybe a separate AI-slop testing list would be appropriate.

It's probably easier to just give them a different colour in our lists. I'll speak to Kirill regarding it.

Revenge is closed source:
https://www.revengechess.com/

Its a continuation of Open source pedone chess engine, revenge based on CCRL color green code, definitely a free but closed source.

For Ginkgo santiago is private also based on CCRL color code.

In case this may help too, you can check revenge site above and visit ccrl blitz for ginkgo santiago
