Strelka is already proven to not contain any part of Rybka code, because Yuri is smart enough to change variables name. He is also smart enough to change the order of variables declaration.

He is completely right when he think he can fool us all.
I am convinced that strelka contains parts of Rybka's code but I am
not convinced that Rybka contains part of Fruit's code(Strelka also contains very little of Fruit from my point of view and some programmers including Tord Romstad said that Strelka is an original engine after looking at the source).

I remember Tord writing that Strelka is original as his own engine.

The claim that Strelka is based on Rybka1.0 is accepted by most people and this is the reason that Strelka is not tested by organizations like CEGT.

Thanks Oliver, I was already familar with the article. It is the one that includes the famous claim by Vas.
In light of the above, I am claiming Strelka 2.0 as my own and will release it in the next few days under my own name.


Shortly after making this claim others found loads of Fruit-like code in the same Strelka source which Vas claimed as his own. No further statement were forthcoming from Vas? And now 9 months later the promised release "in the next few days" has to my knowledge still not appeared. I suspect Vas regrets claiming Strelka as his own.

People should invent their own engine!


My big respect for the great programmers Bob Hyatt and Tord Romstadt and their fantastic programms that are OPEN SOURCE and no clones.

-Oliver
Unfortunately there have been _many_ clones of Crafty. And probably most every other open-source program around... There is not a lot that can be done to prevent it other than to stop releasing source code...

Occasionally I almost fall out of my chair laughing at things posted here. "accepted by most people"???? :)

The _author_ of Rybka has claimed Strelka as his own code. I'd think that is evidence enough for any rational thinking person...

But the _author_ of Strelka is denying it. So it's his word against his. I am only sure of that formula:

OliThink != Crafty != Glaurung != OliThink.

I already showed a lot earlier even before releasing the source of strelka cases of very similiar analysis between strelka1.8 and rybka1 beta
when it is clear that this similiarity in analysis cannot be between 2 independent programs.

Some testers decided not to test strelka a lot before Vasik said that Strelka is his own program.

I don't follow. The author of Strelka specifically stated that he "reverse-engineered" Rybka, then made some improvements.

Vas already said that claiming strelka as his own is going to be illegal so he is not going to do it

Thanks Uri. I had missed this thread, coming as it did long after my interest in the topic had died down. So Vasik says it would be illegal to claim Strelka as his own, seven months after he had done exactly that. In other words he admits he acted illegally?
