Sting-sf-45 release

[lech]

The last version (4) seems to be weaker than the prevoius ones (2, 3).
I try to change it by this version (correction).
http://www.mediafire.com/download/ezuwk ... g-sf-45.7z
As earlier, Sting is based on Stockfish 211 only (many thanks for authors!), is "one brain in one head engine" (to play and analyse in the same way, without tricks and parameters), and I can't do 64-bit version (sorry!).

The main goal of my work is to prove that an artifical inteligence (anything it means) is not nedded for chess and people.
I promised that the next version (> 4) will solve the big problem - draw eval (fortress). It means: how to get the zero value in draw positions in less than 100 moves (the rule 50).
But the version (45) doesn't do it!

Of course, I am working at this.
I have some idea, but it is not easy to do, maybe only to tune it.
I need a help, examples where the idea doesn't work well. I set the idea to work only if eval of any position in search is >= or <= the pawn value. I think, it should help (so long).
If you want to help me, please try this unofficial (32-bit) version with draw (fortress) detection:
http://www.mediafire.com/download/em61v ... g-sf-X.exe
(let me know if you want the source code, but it is not ended!)
Maybe, thanks to you, the next version of Sting (5) will be a great event.

[Graham Banks]

Thanks Marek.
Do we call this Sting SF 4.5?

Graham.

[lech]

Yes, of course Graham, sorry!

[Graham Banks]

........and I can't do 64-bit version (sorry!).

Perhaps Jose can help?

[lech]

I closed the link to sting-sf-x.exe. It was rather a wrong idea. I apologyze for my passion, maybe a curse.

[lech]

........and I can't do 64-bit version (sorry!).

Perhaps Jose can help?

Graham, I think it has no sense to ask anyone. I decided, in a few days I will publish version 5 (draw, fortress detection).
I have no time to find the best shape for my idea.
I am happy that the extremaly difficult position the next Sting will solve (dual core less than 1 hour)

It is possible (maybe) my idea (without tunning) can return ZERO in some non-draw positions, but I made many to drop it in next depths.

Many thanks Vincent for your examples. One of them is very useful and show that my idea (sting-sf-x) needs much more work.
The problem how to get the value draw leads to the reversal question how to avoid a zero value. The second question seems to be much more difficult. It is not easy to get the proper code even if an idea seems to be be good.
In my warm head there are new ideas and I believe in the future I will do it much better, though.

Thus the version 4.5 of Sting remains now my new official release and if Jose is able to help me too, 64-bit compilation is welcome.

Many thanks for any help again and sorry for the confusion,

[velmarin]

No problem, Marek.

The current code by mediafire is valid?.
