New engine releases & news 2021

[jhonnold]

I have released Berserk 4.2.0.

This is mostly a release around LOTS of small changes. Hopefully ~50-60 Elo gain over 4.1.0

You probably need stronger opponents by now.

Hi all!

To my big surprise, I saw that my older engine, Haddock, was actually participating in a tournament organised on this forum! This is of course fine, but this engine is discontinued, so it will not get any better...
However, I'll keep it up on github. Perhaps it can be of use to someone.

I am now actively working on my other engine, DoctorB, and now I have released v1.0.0.

My aim is to build the best engine that I can, while keeping things a bit original.
If you have any questions or remarks, feel free contact me

Hi Hans,

1. I'm surprised you have discontinued Haddock, the dev version is 300-400 Elos better than 0.2.1.

2. The DoctorB executable inroduces itself as version 0.1.0, while you say it is 1.0.0. Please talk to him.

A couple notes:
To run this effectively, a processor that includes AVX2 (like BMI2) is almost mandatory, otherwise you could see an NPS decrease of up to 50%.
If you're not sure what instruction sets your CPU includes, I've included a complete of bmi2 and avx2 processors on the main page...see

ATM the nnue network must be named nn.bin and reside in the same directory as the Fire 8.N executable.

The NNUN implementation is completely different than SF, and utilizes a modified version of Daniel Shaw's/Cfish excellent nnue probe code:
https://github.com/dshawul/nnue-probe
Many thanks to him and Ronald de Man for that!

The download includes the top reinforcement learning NN (according to my extensive testing) trained by Sergio Viera last year.
I think you'll see that this, combined with Fire's search translates into some real interesting, unique, and strong engine chess.

7000 games testrun of Fire 8.N Raptor-net avx2 finished. The Raptor-net is not part of the official Fire 8.N-download, the Raptor-net was commited by the Fire-author 1 day after the release of Fire 8.N.

Hm.... over time, more and more engines written in Rust seem to pop up, even from the past. I'll add this one to the list. The ones I know of on top of my head are:

Rustic (my own engine)
FabChess
Asymptote
Little Wing
Chareth
Crabby (old: only compiles on one single nightly version of Rust)
Cicada (old: compiles, but with a huge amount of warnings)

And now Haddock. Did I miss any somewhere?

FoxSEE, Velvet, Tinman, Rustfish, Scam, Chessier, Odonata and Ragnarook.

FoxSEE, Velvet, Tinman, Rustfish, Scam, Chessier, Odonata and Ragnarook.

Darn. And I thought to be somewhat original by choosing Rust. Seems I should have chosen something more esoteric

Chessler, Ragnarook, and Scam don't seem to be in the CCRL Blitz list (yet). I completely missed Odonata, because the first version of Rustic was already 500 Elo stronger, so Rustic was never in the under-1600 part of the list.
