Hi all,
I'm totally new to this forum and I salute everyone!I am a big chess fan (I own Rybla 2.3 UCI &Chess Openings 2007).My professional interest lies in mathematics and lately (only as a hobby) in A.I. I would like to ask Vasik if and to what degree can information regarding Rybka's source code be released in public. Is there a research paper on the evaluation function of this chess engine. I'm of course, fully aware of the relevant privacy that need's to be maintained but are there any plans on releasing for instance "handicaped" open Rybka source code for computer chess programmers and fans! Is there a research paper available on Rybka's evaluation mode? I hope my question does not sound totally ridiculous.
Yours.

Are you joking? Rybka Source code is completely private.
Why to offer a wonderful gift like that, to some hungry wolves for nothing? :-)
Why him would offer his program in this absurd way and throw his good work in the toilet?
Of course that is only my opinion. Maybe Vas will tell you, what he thinks about this.

Gambitto.

Rybka Source code is completely private.Its has been rumored that expert hackers can get the source code of the program. But I am not sure if its 100% all programs and softwares. Any ideas?

Well, that depends on what you understand under ´source code´.
Of course you´ll never get the true C-source code, but it´s quite easy to get an assembly listing of Rybka with a good disassembler - there´s no need to be an ´expert hacker´ for this! ;-)
But: to analyse (and understand!) the algorithms that Rybka uses by only looking at this assembly code is nearly impossible - or at least it will take you years!
Yes. fhub is right.
Of course it is possible to see the Rybka code using a good disassembler. But of seeing the code to understand it, there is a huge difference.
Understand the whole code (Hundreds of pages!) it seems a task almost impossible. Only the brilliant brain of his programmer, can recognize and understand what he made :-)

They can acquire the source code, but by the time they do Vas would have already launched a stronger and more complex engine.

Vas has said he might release the source when he retires. Until then, Toga II is going to remain the strongest open source engine for a while.

* Toga II 1.3X4 Beta release ased on Fruit 2.1 code, by Thomas Gaksch and Fabien Letouzey. Zip file contains windows excutables for 32 Bit & SSE2, 64 Bit Intel & AMD systems with source. NOTE: The 64bit version will not work with EGBB due to egbbdll.dll's being 32 bit.

And when he will retire? I don't believe that it will be soon.

Actually, it's a good question. It's not so much a need for secrecy and keeping other programmers down, it's a matter of time. You can either write good code, or write good papers about your code. If you're trying to do both, you're probably going to end up doing neither.
At some point, though, all of this fun is going to end and then sure, I'm open to anything.

Thank you for your time :)

This happens in other fields as well. Frank Lloyd Wright frequently complained that while he was out designing and building hundreds of structures, Le Corbusier would design and build a structure every five years and then write 30 papers about it.
Complained or laughed? :)

Neither :)
most of the time i'm skeptikal. It's an idiosyncratic thing. :)

Probably a little of both. Wright built a lot more buildings, but Le Corbusier got a lot more opportunities to trash Wright's work than vice versa. Wright would have gotten the last laugh though. The great majority of the buildings he designed and built are still standing whereas most of Le Corbusier's buildings crumbled into dust (or were buldozed out of existence) shortly after they were built.
A few years ago, a friend wanted me to buy and renovate a Le Corbusier designed house in the Los Angeles area. He told me this was my chance to own a masterpiece. The house turned out to be shockingly ugly. Even my dog found it repulsive. Needless to say, I passed on this great opportunity to own a piece of history.

Actually, I've never heard of Le Corbusier. Doesn't sound like I'm missing much :)
