Osipov didn't ever tell that Strelka is a clone. Make a check.
He was trying to emulate Rybka play. He succeded. Then he made a joke naming his engine in "-ka 1.0 beta 32-bit" style to make some noise and some fun of it. Unfortunately, the computer chess scene doesn't have a sense of humour at all :) Sorry, guys, but some of you are so dull... :)

Best,
My understanding is that the Belkas are just beta versions of a modified Strelka put together by the WildCat author.
I doubt there will be an actual final engine release called Belka. Probably just a new and improved Strelka.

Another post from the Rybka forum today:
Ray,

first, I appreciate the work of the CCRL. I understand also that internally, this is a difficult topic for you, as you have some Strelka advocates in your team and as this has turned into an emotional topic for some people.

Your explanation, however, just doesn't cut it. Why don't you test Patriot or El Chinito or any of the other clones? Since when are you obligated to wait for a court case? Explain it to yourself however you like, but you are making a statement.

I am not sure of the definition of a clone but it is clear that strelka is based on rybka.

The fact that the behaviour of strelka is almost the same as rybka is no accident.
I am not expert of definitions to say what it is a clone.

I think that generally if a programmer watch the output of program X and write a program Y to generate the same output or almost the same output
then we can say that Y is based on X even if the programmer of Y only watched the output in order to write Y and never looked at the source of X.

I do not know if the programmer of strelka decompiled rybka and I only know that the fact that the output of strelka is similiar to rybka beta is no accident so I can say that strelka is based on rybka without saying if it is based on rybka's source or based on rybka's output.

Nobody can watch the output of a Chess program in order to write a program with same output including similar Bugs and same behaviour in strange positions.

Can you tell such a thing about Rybka beta and Fruit 2.1?
Thanks,

If fine equals in denial, I believe you. Thinking about it, Vas would probably not talk to you. He probably has better things to do. Therefore perhaps its better you continue in wallowing in your own ignorance.

We have a new engine today (another one).

It's called........Vulga.

I can't think what or who they named it after.......

Of course, instead of sharing the facts you uncovered about Strelka=Rybka, you are badly trying to display a sense of humour playing upon names you didn't understand... But only thing you succeeded to show is that you're not good neither at uncovering secret clones neither in playing upon words.
Sorry.

Sorry.
If any original author would like to make a "Spanka" please feel free to contact me.
