Andscacs - New version 0.921 with source

[tttony]

Cool!

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

[cdani]

In debug.h comment the
#define WINDOWS
and activate the
#define LINUX
Hope it works with this.

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!

So far I can get it to compile pretty easily on the macOS - but it crashes right at the start

Code: Select all

Current executable set to 'andscacs' (x86_64).

it looks like a buffer overflow or seg fault

Unfortunately no, and the forum software does not accept tzhe text of the error message....

I was wondering if you can add parameters to Andscacs like the one Texel has ? I very much like to tweak and tune the engines. The more parameters Andscacs has, the better

You can do it yourself:
* Decide what eval parameter you want to add. See avaluacio.cpp, in the function carregar_fitxer_avaluacions. For example we take this line
BonusAlfilSuportatPerPeo = FerPun(5, 9);
that means Bonus for bishop supported by pawn.
* in es.cpp add something like this more or less in the line 140:

Code: Select all

afout("option name BonusAlfilSuportatPerPeoMg type spin default 5 min 1 max 100\n");

This is only to show the parameter to the user. The "Mg" is a visual reference to middle game, so we will create a parameter to modify the "5". The "9" is the endgame part of the value.
* in es.cpp add something like this

Code: Select all

if (!_stricmp(name, "BonusAlfilSuportatPerPeoMg")) {
   int tempv= atoi(value);
   if &#40;tempv<= 0&#41;
     tempv= 1;
   if &#40;tempv> 100&#41;
     tempv= 100;
   BonusAlfilSuportatPerPeo = FerPun&#40;tempv, PunF&#40;BonusAlfilSuportatPerPeo&#41;);
&#125;

You can add it for example under this code:

Code: Select all

if (!_stricmp(name, "LoadHashfromFile")) {
   read_hash_binary();
}	

So this will change the mg part of the value, not changing the current eg part. If you where modifying the eg part, you have to do:

Code: Select all

   BonusAlfilSuportatPerPeo = FerPun(PunI(BonusAlfilSuportatPerPeo), tempv);

That's it!

macOS changes in hash.cpp

Code: Select all

#ifdef LINUX
	if (memhash)
		free(memhash);
	  memhash = calloc(sizeof(unahash), xx);  //macOS auto aligns to 16 bytes in its ABI, hence clang/gcc macOS is missing aligned_alloc in its C11 implementation
//	memhash = aligned_alloc(sizeof(unahash), xx);//not for macOS
#endif

also the makefile downloaded was missing magics.o on the OBJS listing , but that was pretty easy to identify..

working on optimizations now - will post later today , still need to test under xBoard

Unfortunately no, and the forum software does not accept tzhe text of the error message....

Is like you have not defined the #LINUX
#define LINUX
I hope is this. The problem with linux is that I don't have any practice. I work mostly only with Windows.
If it does not work, can you post here the modified debug.h file if you want?

[cdani]

Success!!!
...
will work on optimizations now

Nice! Thanks!!

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

If is the default license, yes. No problem for me.

I was wondering if you can add parameters to Andscacs like the one Texel has ? I very much like to tweak and tune the engines. The more parameters Andscacs has, the better

You can do it yourself:
* Decide what eval parameter you want to add. See avaluacio.cpp, in the function carregar_fitxer_avaluacions. For example we take this line
BonusAlfilSuportatPerPeo = FerPun(5, 9);
that means Bonus for bishop supported by pawn.
* in es.cpp add something like this more or less in the line 140:

Code: Select all

afout("option name BonusAlfilSuportatPerPeoMg type spin default 5 min 1 max 100\n");

This is only to show the parameter to the user. The "Mg" is a visual reference to middle game, so we will create a parameter to modify the "5". The "9" is the endgame part of the value.
* in es.cpp add something like this

Code: Select all

if (!_stricmp(name, "BonusAlfilSuportatPerPeoMg")) {
   int tempv= atoi(value);
   if &#40;tempv<= 0&#41;
     tempv= 1;
   if &#40;tempv> 100&#41;
     tempv= 100;
   BonusAlfilSuportatPerPeo = FerPun&#40;tempv, PunF&#40;BonusAlfilSuportatPerPeo&#41;);
&#125;

You can add it for example under this code:

Code: Select all

if (!_stricmp(name, "LoadHashfromFile")) {
   read_hash_binary();
}	

So this will change the mg part of the value, not changing the current eg part. If you where modifying the eg part, you have to do:

Code: Select all

   BonusAlfilSuportatPerPeo = FerPun(PunI(BonusAlfilSuportatPerPeo), tempv);

That's it!
Anything just ask.

Thank you Daniel..will be tested

I was thinking of parameters like these:

Here is the picture how Texel parameters look like:
