Graham, I just noticed that the Eonego Github repository contains an avx2 binary now. Version 0.1.0
Thanks. :)

Hi guys,

I'm really glad you 'enjoy' my engine :D ..
Couple of things: I used to, whenever I'm looking into newer programming languages, especially if they are a bit more on the low level side, fool around coding some chess engine. Never anything serious, always HCE and they never been better than approx. 2.2k I d say.
Nowadays looking into newer languages doesn't make a lot of sense without leveraging the sota tools there are.
Therefore I ended up creating this engine with zig. Since at least in my mind it seemed to be quite strong and maybe the architecture etc. might be interesting for others too, I thought submitting it to CCRL makes sense.

If you don't want engines like this to be submitted, thats obviously completely fine with me. Please update your CCRL submission rules then though. I guarantee I wouldn't have bothered then.

The only CCRL testers in this thread are Gabor and myself, and I don't think that we've said anything amiss regarding your engine?

Sorry about that then :D . I just got the impression people are somewhat 'annoyed' with the number of engines popping up. Which i'd get from a effort perspective of course (but I wasn't aware of doing something wrong by submitting, which you now clarified I didn't).

Hi Stierms,

I am very interested on your engine after visiting it. However, I dont know how to bring this engine in the Android environment specially its a zig engine.

How to compile zig engines to android?, I want this engine but I couldnt access to it yet.

I run an android chess engine tournament and I collect engines with an android builds.

could you provide an android builds?

Hi Arzam,

Glad you think it's interesting. I'll look into it this evening (CEST). And hopefully upload the apk soon after.

Cheers
