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.

Re: A complete 2000 lines of code engine

I was curious how our engines compare because we're at similar points of development: we've created bitboard engines with a robust alpha / beta search function but a minimal evaluation function. So I ran a head to head match last night at a time control of 2m+1s. I get very different results than yo...

Re: MadChess 3.0 Beta

I added passed pawn evaluation to MadChess 3.0 Beta. This increased the engine's playing strength by 119 ELO. Booyah!

MadChess 3.0 Beta is now rated 2329 +/- 14 ELO at bullet chess.
