Tenax-NNUE 1.0 released

[Carotino]

Hello everyone,

Tenax is a UCI chess engine written in C and started as a private hobby project to see the engine improve over previous versions. This version of Tenax has support for Syzygybases.

Tenax is an AB chess engine and evaluates positions with a neural network, for this reason requires a CPU with the SSSE3 instruction set (which almost all CPUs have), and will not run on systems lacking these instructions. AVX/AVX2 have become ubiquitous in modern processor design, and are necessary to capitalize on the full strength of Neural Network method.

To choose the best compilation for your computer, see the ReadMe.txt file.

Tenax, the illegal closed-source Berserk clone?

What engine did you clone now, for NNUE? just berserk master?

edit: yeah, courtesy of Alexandria author, it's berky 8.5:




What's the point of this?

Congrats on figuring out how to clone a nnue version of berserk!, i'm sure it took a lot of extra skill compared to just cloning the hce one.
For anyone wondering it's not just 8.5.1, the search has been altered (enough to at least make the pvs not match), and in perfect cloner fashion the clone is weaker than the original.

ran a few games, i'm not willing to waste more compute on this, i'll just say that being a superior dev i can at least git clone things without losing 2 digits of Elo.

Gulp!! It was not my intention to break the law. What do I need to do to make this Mod legal?

Allow access to the source code for anyone to whom you've distributed a binary. Which means your download link above should either include the source, or a link to it.

Uh, ok!
I'm not a professional, I think my edits are not very interesting. Anyway, here's the new link.

Well if they're not very interesting, then you probably should have never made the post to begin with, yeah?

Interesting and even CCRL could not resist to test version 0.79 ;)
Of course Tenax never appeared in the XB/UCI chronology because there never was not a clone/illegal derivate from 'Munter/Munto/carotino' whoever...

Now it can be adjusted as one of the Berserk versions.

Berserk 4.50 is not tested in CCRL Blitz, but 4.40 is more than close in the Blitz list.

Gulp!! :o It was not my intention to break the law. What do I need to do to make this Mod legal?

would be 15 years too late anyway...
