Andscacs - New version 0.921 with source

[Volker Pittlik]

...
Maybe you have not seen the post of Michael saying that I had forgotten to add magics.o in the makefile. Just download again the source and replace the makefile.

Indeed I missed that. Now it compiles error free and runs fine so far.

thx

Cool!

The source has no license so I guess it's under public domain?

About the license, Elcabesa just told me that the WinGroupAffinity part of the code taken from Stockfish is incompatible with public domain license. Maybe the best is to remove it from Andscacs. In fact nobody is using it that I know. What do you think about? Thanks.
I just added it if I remember well when Ipmanchess asked to test Andscacs with more than 64 cores, I think.

[cdani]

Where do I have to change the things you just mentioned, so I could get Andscacs parameters ?

In the es.cpp file.
The problem is that if I add a few parameters it will not make much sense. And adding a lot of them is just a lot of work I'm sorry.

About the license, Elcabesa just told me that the WinGroupAffinity part of the code taken from Stockfish is incompatible with public domain license.

I'm not a GPL expert, so I really don't know all the implication of licenses of pieces of code that we can find in internet.

Thanks for this nice gift.

I tried to make it compile under clang under Linux and ran into a couple of these errors:

Sorry yes, I mean you suggested it

Since is a strong program I think you should choose a license: https://choosealicense.com/

Anyway a code without license has copyright https://blog.codinghorror.com/pick-a-li ... y-license/

I used gcc also to compile it for linux.
I will clean those warnings, thanks.
About the error at finals.cpp, at first sight I don't see what can cause the error, specially taking into account that works well with other compiles. I will think about it. Thanks.

Thanks a lot, Daniel. Good luck the rest of the way.

Hello. So here it is the version for the second stage of TCEC. Is really a minor version, with luck +5 elo.

Changes:
* Improved various pawn structure evaluation parameters.
* Move search improvements.
* Improvement of various imbalances.
* Improvements in some endgames.

http://www.andscacs.com/downloads/andscacs0921.zip

As promised the source code:
www.andscacs.com/downloads/andscacs921src.zip

Is a Visual Studio 2013 solution. Also it contains a makefile for Linux.
Michael will try to make a Mac version, thanks to him!

Daniel ,

What a great treat you gave to the CC community today. I love your engine a very unique style and very strong.

This run was just for fun and it was very quick tc (24 sec base)
K11.2.2 has really picked up its game with these micro time controls but I believe this may be a slightly lucky run. I checked the pgn and there was no losses on time by engine. Almost 500s point higher than Fruit 2.2.1 in this run.
