Re: New engine: Stash

Congrats Morgan. Welcome to our community and our addictive hobby. As Marcel said in an earlier post, I chronicled the development of my chess engine on my blog, including measuring the ELO strength improvement of each feature. Mine is not the strongest engine but hopefully the code snippets and ELO...

Re: Greetings and new Eubos chess engine

Ah, I see. Well, anecdotally, you've observed the gap between engine vrs engine ratings compare to engine vrs human ratings.

Re: Greetings and new Eubos chess engine

Congrats Chris on your engine. A stable program that plays a timed game of chess is a big milestone. That's cool that it plays on Lichess. Do you have any idea what its rating is against humans ? Or does it only play other engines? I ask because there's definitely a discrepancy in human ratings and ...

Re: MadChess 3.0 Beta

Thanks David. All the coding I’ve done lately has been work related. Hopefully I can get back to MadChess this spring. I know I will, it’s just a matter of finding time.

When I do I’ll be sure to watch it battle Orion on the chessboard :)

Re: Particle Swarm Optimization Code

I plan to "texel tune" with PSO, not play game.
Yeah, that's what I did. I used PSO to find a better fit of eval parameters to game outcome by minimizing the error between eval prediction of game outcome and actual game outcome. I did not use PSO in conjunction with playing actual games.

Re: dotnet and winboard

Still a problem that my engines name appears to be "dotnet" in winboard.
Run a dotnet publish command to produce an executable. Create a self-contained deployment. Then register that executable in Winboard.

Re: " End of an Era" is coming?

Current score:: 10.5 vs 9.5 ,in favour of Leela... End of an Era.
I'm amused by the vastly different level of rigor for developers and fans. Twenty games is good enough for some fans, ha ha.

Re: A complete 2000 lines of code engine

Looks like Minic has time management issues for games with incremental time controls. I ran another match between MadChess 3.0 Beta and Minic 0.28 using a time control of 40 moves in 4 minutes. Minic won the match. # PLAYER : RATING ERROR CFS(%) PLAYED W D L (%) OppAvg 1 Minic 0.28 : 2407.0 19.7 100...

Re: A complete 2000 lines of code engine

Yes, perhaps it’s a time management issue. I ran the match overnight and did not watch the games. I simply verified in the morning there were no abnormal terminations.

When I get home tonight I’ll test at 40/4 and update this thread with my results, Minic’s NPS, etc.
