Sure, but the so-called "facts" in the Rybka base are still disputed to this day.hgm wrote: In computer programming it are the facts that count.

A pity that original source code was not available, that would have enabled a far more reliable verdict to be reached. Of course the ICGA rules themselves were not exactly clear either, there is rooom for interpretation there too.
Indeed, the main and undisputed fact is that he did not show any source code. That in itself is sufficient reason to ban him from ICGA tournaments, but it does not constitute proof that it was a Fruit derivative.Modern Times wrote:Sure, but the so-called "facts" in the Rybka base are still disputed to this day.

But whether it is, can be decided by examination of the binary. Opinions of those that have not done that carry no weight whatsoever.
Those that keep pointing at Rybka like it is some panacea for the current predicament of computer Chess completely miss the point. Rybka is history, Stockfish / Komodo / Houdini / Ivanhoe are the present. The real problem is Ippolit, its questionable legal status, its shady authors and its frequent cloning.
A good point !!vittyvirus wrote:Rybka was NOT a Fruit clone. Most ~2800 engines do calculate around 100-500 kNodes/sec on my system. Rybka, which merely calculates 100 kNodes/ sec with single core on my system, is rated 3161! Its evaluation function is far superior than even engines today, and I belive that was the reason Vasik didn't want to show them the code. They, at that time, didn't accuse any other engine, that was enough for Vasik to believe that they're trying to steal code.
But after all its US who are supposed to stand for him. It doesn't make a penny worth of difference to ICGA if they lose CP Geniuses.Sedat Canbaz wrote:A good point !!vittyvirus wrote:Rybka was NOT a Fruit clone.

Actually this issue is not so complicated as it looks...
Simply,
Some of the programmers were tired to be beaten on real Arena!!
And finely they found the right way to beat Rybka: via papers !!!

I'm sure that if Vasik wasn't discriminated against he'd would have not left Computer Chess! Somebody call him back!Sedat Canbaz wrote:Sure...vittyvirus wrote: But after all its US who are supposed to stand for him. It doesn't make a penny worth of difference to ICGA if they lose CP Geniuses.
But in the same time (after banning Rybka)
Exception me, there are many many chess friends who does not pay any penny to IGGA too
Look at latest WCCC,
Only 6 participants and the champion is Junior, but in reality is it true ??
I mean, Junior is the strongest chess engine in the world ??
In other words,
Without Wladimir Klitschko, Mike Tyson ...we can not say:
- This is a 'real' World Championship )) !!
