More proof of Strelka cloning

[Uri Blass]

The reasoning is seriously at fault thrice over:

• It is mistaken to assume that the selection by an author of a UCI message format will be at random.

• It is mistaken to assume that evidence of copying a UCI message format is evidence of copying anything else.

• It is mistaken to assume that copying a UCI message format amounts to cloning.

Your conclusion is wrong.

the uci test was only an additional evidence and Martin Bryant did not claim that this evidence with no help is enough to claim cloning.

People make assumptions based on probability all the time.

OK, but then, why a programmer capable of cloning such a complex thing as Rybka would leave a so easily changeable feature as are the messages as a yelling proof of his wrongdoing?

Even me could do at least the effort to hide that. I mean, at least putting OFF those functions.

Still bewildered....

I guess that the programmer really did not care about the fact that other will discover that his engine is a clone.

The problem is that the "proof" is all biased towards finding similarities...

If you are using the UCI implementation as evidence, then how do you explain the "ucinegame" typo in Strelka 1.8 that does not exist in Rybka 1.0 Beta? I'm sure that's not just an anomaly and that other similar differences could be found.

He cares. Remember he almost cried when accused the first time. But, again, IF he cheated, why he left a track as the one pointed by Martin?

Indolence, forgetfullness, what?

Not only is this thing definitely a clone of Rybka, it's not even a well-disguised clone of Rybka!!

For me the question is, does the author actually claim that his engine is not based on Rybka? As far as I'm aware we haven't heard from him. It seems strange that others are defending his integrity, when I imagine he would probably admit Strelka's dependence upon Rybka's code rather than prolong a farce.

It seems that it was type of a game by him to see if people are smart enough to find that it is a clone.

In the first time he tried to hide it better and had success in convincing other people that it is not a clone.

Now he decided to do his program more similiar to rybka and wanted to see if people are stupid enough to believe that it is not a clone.

People make assumptions based on probability all the time.

And get into a logical mess. People make assumptions about probability all the time. The thread is about proof of cloning. Evidence of possessing apples isn't evidence of stealing pears.

...I'm so going to be flamed for this comment...

"This is precisely why I am NOT and advocate of open-source engines..., especially strong engines..."

Example open source engines with rating, say, under 1800 are fine and allow the community to grow with newcomers learning the basic techniques..., but

Why have open-source engine in excess of 2500??? It hurts the chess engine community far more than doing anything good!

That's correct.
