Changes are detailed in the release notes, as well as the expected Elo (anywhere between 2250-2350).

Congrats

Thanks very much I’m excited to see how it will perform on the CCRL

Edit: it appears I’ve forgotten to merge dev into main however I’ll need to fix that

Is the tuner not in the repository, or am I not seeing straight anymore after 16 hours at the computer for work and chess programming...?

Nope check my edit in my previous answer. I’ve been at my computer most of the day as well. The fatigue seems to have gotten to me first actually.

Alright apologies, that issue should be fixed now

Velvet 3.0.0: https://github.com/mhonert/velvet-chess ... tag/v3.0.0

The major feature of this new release is the support for multi-threaded search using the Lazy SMP approach.

Interesting... another Rust engine. In some spots (such as the FEN reader and UCI handling, but not limited to those), Velvet uses a very similar architecture, structure, conventions, and sometimes even naming as Rustic. The engine was started a year later than Rustic, and seems to have progressed at rocket speed.

I don't mind if that's the case, but if so, some credits would have been nice. It _could_ of course be that the use of the Rust language makes people naturally use some architectures over others. Still, I get the feeling that Rustic may have been an inspiration to early versions of this engine, in the same way as VICE was an inspiration to the earliest versions of Rustic (but code all except the castling permission table has disappeared before Alpha 1).

Hey,

First:
This thread is really not for discussing releases/engines, but announcing them... If you really wanted to discuss something about a release, please open a new thread... It is easy for the engine releases to go unnoticed thanks to all chit-chatting in the thread.

Second:
Your reply got me curious and took a look at the engine source code especially the files you mentioned, all "influence" that I saw, was exact same file extensions, and a bunch of commonly used words like FEN and read (even the fen reader function is called differently in the two engines).
Maybe you are both influenced by Rust conventions and Vice, but yeah I could be wrong...

Anyways, Velvet and Vajolet are the strongest two chess engines written in Rust, with BlackMarlin skyrocketing too, it is hard to guess which one will win the race in the coming few months

Lozza 2.0a (already around two weeks ago)
https://github.com/op12no2/lozza

Thanks Guenther. To Graham et al, please don't waste your time testing - just a minor bug fix for a Lozza sim test that Ed did for me. Lozza is inspired by fruit and her eval is still fruit-like (and currently resisting all attempts to morph into a net). Result was good:-
