New engine releases & news H2 2023

[Frank Quisinsky]

Yes, v4.1.0 was great, but the others are all close.
In my humble opinion, midgame strength is the most important thing these days, because endgame strength is about the same for many engines, and in my opinion is no longer important. In the late middlegame Uralochka is stronger, but not in the early middlegame. I think its a hard fight between Uralochka and Velvet, but also with different others. So for opening freaks Velvet is a real event and one of the most interesting developments today ... again ... for me. I can speak for myself.

hello,

I've just released Cheng 4.42
https://github.com/kmar/cheng4/releases/tag/4.42
expected elo gain: very modest, maybe 12 elo against other programs, but that's up to independent testing to determine

notable new feature added: syzygy tablebase support (via pyrrhic)

have fun

Thanks Martin
Cheng 4.42 will definitely play in the MCERL cycle.

Hi

Long time no see. I hope you've had a good Christmas and will have an even better 2024.

Even though there hasn't been a new version of Rustic for the last 3 years, that doesn't mean I've forgotten the engine. I'm still updating Alpha 1, 2 and 3 to keep up with the latest changes in Rust and to be compatible with the latest versions of the (very few) libraries it uses. Today I've released Alpha 3.0.4, 2.3, and 1.4. These are just maintenance updates with regard to the Rust language and libraries. Their playing strength should not have changed.

New versions

I've also updated the 4.0-beta branch to the latest-everything. The two things that (still) need to be done are:
- Implement "time" and "otim" for the XBoard-protocol. AFAIIK, this will finish Rustic's XBoard implementation.
- Write a (simple) Texel-tuner, to replace the values I got from Lithander (MinimalChess/Leorik) a long time ago.

I do hope to finish this in the somewhat near future, so I can (finally) release Rustic 4.0.0 (*), which should have a massive jump in playing strength over version Alpha 3. I hope I will have more personal time than I had in the last 3 years, which were very busy. (The corona pandemic and a massive change in government regulations caused a huge amount of change in the software at work. I worked long hours in those years and I really didn't feel like adding some more programming at home.)

(*) Rustic 4 would drop the "Alpha" moniker. Having both the UCI and XBoard protocol, a magic number generator and a tapered and tuned evaluation (and its own built-in tuner), I see this one as the first 'complete' version for didactic purposes. I also target this version to complete the book at Rustic's documentation site.

Thanks for your interest

GREAT so lets make believe that Rusti is playing with the Black Pieces here against Stockfish playing with the White pieces, lets see it in real action with human pieces ===>https://www.youtube.com/watch?v=fmfW35fSE1o
