Re: Why Vasik Rajlich keep the silence?

Exactly - the onus is not on Vas to do anything if he doesn't want to. He has done nothing wrong in this affair, so why should he be copping the crap? Wrong. He has created Rybka so he is responsible for all these things happening here! :D And instead of working improving Rybka, he should answer to...

Re: Poll: Do we need a "Strelka is/isn't a clone"

This is getting ridiculous. Right now, I count ten different threads about the Strelka/Rybka issue on the first page of the "General Topics" subforum. This is the second time that this forum becomes a Rybka forum. This time is not a pure Rybka forum, but a Strelka-Rybka forum, but the whole noise i...

Re: No rumors, Strelka is a clone...

This is nothing but a morbid obsession. Every work is based on something, no one lives on a desert island. Yes everything is based on something previously discovered by others. But this is irrelevant to the clone cases. One can use the ideas from open source engines. But he can't use the code of ot...

Re: No rumors, Strelka is a clone...

The fact that such a definition would make Rybka, Hiarcs as also every other closed source engine, a possible clone of an open source engine, does not mean we should reject the definition. Because the arguments of the definition are logic one's. Why do you believe that one person can not take the s...

Re: No rumors, Strelka is a clone...

There is also the case that a clone can produce different results from the original engine in ALL positions. That is the case of taking an engine's source and make heavy modifications, that is build your engine on other's ideas and code. This would still be a clone..... Interesting. So maybe Rybka ...

The code he has send was Strelka 1.0 beta.
Not the Strelka 1.8 UCI.

Re: No rumors, Strelka is a clone...

Strelka was able to find the mate, Rybka wasn't. Rybka's +320.00 score is a mate announcement. So it found the mate. Strelka also first considered Qd5, Rybka didn't. Therefore Strelka is not a clone. This is not correct logic. This logic implies that a clone of an engine should produce the same beh...

Re: No rumors, Strelka is a clone...

Both Rybka 1.0 and Strelka don't contain any EGTB code. Though I agree it could be some library code, theoretically. It could be some library code and coincidentally only Rybka 1.0 beta and Strelka have it? No other program. OK we may accept this. What about the positions Uri posted? This has nothi...

Re: No rumors, Strelka is a clone...

Can´t you imagine that it might be just a small typo when writing such hex addresses? In fact the Rybka address range should be 25AC8-27 3 7F hex, and this makes both blocks the same size. Well that makes sense too.... :D (BTW, 6328 bytes - that for your ´basic logic´ ... :wink: ) Yes absolutely. I...
