Re: New engine: Ippolit
Sorry, but there are doubts about this being "new"and in fact being an illegal clone of Rybka. I think linking to this will not be allowed on the forum.

are, by definition, not smart enough to debug it.

Re: New engine: Ippolit
Could you please provide some reliable proof of this engine being a clone, besides "there are doubts" and "I think"?Eelco de Groot wrote:Sorry, but there are doubts about this being "new"and in fact being an illegal clone of Rybka. I think linking to this will not be allowed on the forum.

Statistical correlational analysis, source code analysis, pv output, something else?
Sorry if this question has already been discussed here, today is the first day I read about this engine.

Re: New engine: Ippolit
Hi,
This is not new, at least for people who real know something about computer chess. All who read previous posts and can read between the lines can confirm this. The sourcecode is buggy and needs to be corrected for the engine to run properly, eventhough the displayed PV look strange
I am sure Harvey won't complain about this one. He is still busy letting Fritz 12 calculating the mate in one mentioned one week ago...

Re: New engine: Ippolit
It has been discussed Vladimir but as we would rather not draw attention to it, none of the discussions are still there. Maybe it will be possible to discuss an engine XXXX but certainly not like this. I have not inspected the sources, I am not a programmer and I believe a lot is in Russian, but other programmers here have pointed out this engine is based on Rybka, I have reason to suspect illegally obtained Rybka sources.
I don't know specific details and I don't think I have to know them; maybe the author of Rybka will be available for more authoritative comments on this, if he would care to comment but probably not in a public forum.

Discussion about the Engine and its originality are perfectly acceptable but links to an engine when reasonable doubt exits in the Chess Computer community regarding its originality are notWinPooh wrote:Could you please provide some reliable proof of this engine being a clone, besides "there are doubts" and "I think"?Eelco de Groot wrote:Sorry, but there are doubts about this being "new"and in fact being an illegal clone of Rybka.

Re: New engine: Ippolit
OK, thanks for clarifying.

I will not. I hope, however, that posting the word "Google" is not yet prohibited by computer chess communityplease do not post them again

Re: New engine: Ippolit
Hi, what is the evidence that Ippolit is a clone of Rybka?
It is a serious charge if true, as Rybka is a commercial program and the individual could be sued!
Cordially,
Sean

Re: New engine: Ippolit
this all reminds me on the scenes from medieval where the heretic was burning at stake and the bishop in front asked him: will you confess that you are a sinner ?
i have heard that XY is together with satan.
oh i have the suspicion that x is a witch and can fly on a broom.
did you see it ? no but somebody told me about it.
ok. lets burn the witch and see if she confesses her sin.
in all those discussion i have not seen much evidence.
only imaginations or suspicious positions and main lines.
even the people who have seen source code do not
come with clear statements.

Re: New engine: Ippolit
The reliable proof is the rating, not? A person that never released an engine before enters the scene with a rating of 3200+. What could be more conclusive proof? Even if I had seen him retyping the code of a top engine with my own eyes, there would still be reasonable doubt that he could type well enough to qualify it as a clone. But the rating makes it a certainty.WinPooh wrote:Could you please provide some reliable proof of this engine being a clone, besides "there are doubts" and "I think"?

Or do you doubt the rating is what it is claimed to be?
