GreKo 3.1

[Vladimir Medvedev]

Hello, World!

GreKo 3.1 released. Some changes in search, bugfixes. New perft mode.
At least not weaker than 3.0, I hope. For technical details look file history.txt.

Welcome to download page:

Source code in C++ is available, as usual.

Thanks!

Lots of new releases of open source programs these days.

I tried to compile GreKo 3.1 on my Mac, using GCC and the FreeBSD makefile. I got lots of warnings, but the executable seems to work fine. You could probably add Mac OS X to the list of supported platforms.

Hello, Tord!

Thank you for compiling GreKo under Mac. As to warnings, my gcc under FreeBSD prints a lot of them too (unlike MinGW/Win32 gcc compiler, which seems strange to me). Most part of these warnings is due to signed/unsigned mismatches in array indexing. I put fixing this bug in my to-do list. Anyway, I am almost sure it does not affect GreKo's behaviour in games and analysis.

BTW, is it possible to run UCI engines under MacOS (and under different UNIXes too)? I plan to add UCI support to GreKo in some future release, or maybe write UCI-only version...

Hi Vladimir!

Thank you for compiling GreKo under Mac. As to warnings, my gcc under FreeBSD prints a lot of them too (unlike MinGW/Win32 gcc compiler, which seems strange to me).

It seems so to me, too.

BTW, is it possible to run UCI engines under MacOS (and under different UNIXes too)?

Yes, it is. Under Mac OS X, there are at least four UCI compatible GUIs: Jose, Shredder, Sigma Chess and my own Scatha. It is also possible to run UCI engines in XBoard by using PolyGlot.

Shredder and Jose are available for Linux as well. XBoard and PolyGlot should work in all UNIXes, I think.

I plan to add UCI support to GreKo in some future release, or maybe write UCI-only version...

A UCI version would be most welcome. Then I would be able to use your engine in my own GUI.
