Introducing Toga III chess engine

[Krzysztof Grzelak]

Neither one is not working properly.

Neither one is not working properly.

So toga3_basic.exe has to match up with libnnueprobe_basic.so, etc.

I have it all and it doesn't boot properly either.

Toga III 0.3 is now available. The only update is a new net, trained using reinforcement learning. It’s approximately 20 elo stronger in self-play. The Linux and Windows binaries can be found here: https://www.patreon.com/posts/50193195 (github seems to have lowered its file size limits).

HI!
Could someone compile Toga III also for Linux ARM64 | Raspberry Pi4 and Apple Silicon M1? I'm testing it on Windows 10 ARM64 and I like it!
Same for Night Nurse https://www.patreon.com/posts/night-nurse-0-4b-46830152 , Dark Horse https://www.patreon.com/posts/dark-horse-0-3-47913036 and Fire 8.1 https://chesslogik.wixsite.com/fire/download

We need to support programmers that innovate with their own algorithms

Thank you in advance!

I’m cross compiling from Linux, so my ability to troubleshoot this are limited.

He didn't explain it correctly to you. If you use the basic binary, you have to rename libnnueprobe_basic.so
to libnnueprobe.so, same if you try the sse version, of course you have to move/delete already available
libnnueprobe.so files from the same folder, as the default one from the download is for avx2.

Unfortunately nothing could. My processor is http://talkchess.com/forum3/viewtopic.p ... 1&start=10

We know your processor. You are doing something wrong. Try to read carefully again what I wrote.
Ofc I have tested it myself on even older hardware than yours and even here the sse version runs
after doing what I wrote.

Thank you Simon.

[Carlos777]

He didn't explain it correctly to you. If you use the basic binary, you have to rename libnnueprobe_basic.so
to libnnueprobe.so, same if you try the sse version, of course you have to move/delete already available
libnnueprobe.so files from the same folder, as the default one from the download is for avx2.

Thanks Guenther!
