Oh thank you very much on this one!
What we mean is that we are not yet able to build a static executable due to marche=native which is required for our SSE/AVX code to run.
Therefor one needs to compile the project in order to get a working executable. We are trying to solve this issue at the moment.

I thought it was recommended not to use march=native for compiles you intend to distribute, but instead to target a specific platform (eg march=haswell for a BMI2 compile).

Thank you Finn !!
I hope there will be some windows binary compilations for various architecture
i'm eager to test your engine !

[size=150][b]Koivisto 1.0[/b][/size]

Some strangers and I have written this engine for about 4 months now, and we estimate its strength to be between 2800 and 2900.
We're still figuring out the build process, so for now, you might have to compile yourself. It's a single makefile.

The engine supports all important UCI commands together with additional [b]print [/b](to print the board) and [b]eval[/b] for a detailed overview of the evaluation.

We'd also like to have this run in CCRL, but we're not very familiar with the process. We hope there is interest in testing our engine.

march=native is recommended if you compile yourself. Sadly there seems to be an issue with -static in general. Hopefully, this will be resolved by the end of this week.

There is no process. CCRL tries to test all engines that generate interest, let it be public or personal. Every member makes his choice using his discretion.

Neocortex 1.0 by Justin Stanley
https://github.com/codeandkey/neocortex

I remember that I tried to compile this already in spring, but files were missing IIRC.
It seems this older neocortex version was moved to a different branch.
The current master branch compiles fine now.
I will add it in a few hours to my download site, as the 1.0 release is source only.

I don't think it is very strong right now, but at least it has a lot of original work in it unlike other beef.

Thank you for reporting this, Günther. It is always a pleasure to see someone put in serious work even if virtue will be his only reward. I am currently testing it and it looks it will be around 1400.
BTW, I see your chronology does not list Beef.

The author created a fix for the nps overflow after my report, I will update my download soon.
Surely he likes to be listed at CCRL, or are you currently testing as private person?
(The nps overflow fix will have no influence on strength.)

I have already submitted my games to CCRL, Neocortex is likely to appear on our blitz list tomorrow, maybe even today.
