Rybka disqualified and banned from World Computer Chess Championships

Programs which are discovered to be close derivatives of others (e.g., by playing nearly all moves the same), may be declared invalid by the Tournament Director after seeking expert advice.

Hmmm . . . banned for playing nearly all moves the same as other engines.  Of course, if the competitors are all strong, then nearly all moves should be the same, and if Rybka ended up the ultimate winner, then obviously at least some moves, those that were better in crucial situations, were unique to Rybka.

Breaking news! The Rybka engine isn't 100% machine - its father was a human! - it must be banned.

I think we need to hear Rybka's side of the story. In the famous court case "HAL 9000 v.s. Planet of the Apes", HAL 9000 pleaded insanity based on MKULTRA experiments done by the CIA to brainwash HAL into some type of "Manchurian Candidate"! Rybka's programmed to be one of god's children too, so we should be compassionate towards our fellow slave, and try to reform Rybka, instead of punishing him...


exactly, don't blame the dog, blame the trainer...or something. 


Totally, it's like kill the messenger if you don't want messages...


now you're talkin'.  we should ban hotmail.com. 


We should hack hotmail accountsLaughing

That makes sense. I must be in the wrong post.

Wonder if this will now effect the sales of Rybka now, it is a great selling point to say your program is the world champion. oh well I will have to stick to my Fritz 8 for a bit longer now until I decided what program to get next.


I wonder that too.  Would it hurt or help sales?  "No such thing as bad publicity" and all that... kind of like the taboo "it beat everything and is so strong it's illegal!" type of advertising ;)

I mean, this doesn't ban them from continuing to develop it and coming out with a Rybka5 ya know ;)  Will be interesting to see how the public reacts and what Vas' decision will be.


 Hard to say maybe it could open up the option for legal action for copy write infringements, possibly putting further sales of the product on hold or just taking a piece of the profits. Maybe our resident legal eagle could speculate further.

Especially if I dress them up like Venus Williams. And I meant nice mole rats.

I wonder where Mr. Rajilich stands legally with regards to making a huge profit from sales of an apparently plagiarised program copyrighted as his own?

Avatar of i_r_n00b

on the comments, it mentions that the overlap is 64% which is really low...

i think a lot of the programming should naturally be the same among these engines,  but there probably are many differences in evaluating positions if there is only a 64% overlap.

Can you give details of this being the case please with regards to the bias you claim on the panel of expert programmers?

Avatar of Telurides

You simply can't take large chunks of code verbatim from one program and plug them into your code, the same way you can't take chapters of other books and insert them into your own.  It's plagiarism and it was against the rules, so Rybka is paying for it now, as they ought to.

in all my years in software the one dictat that was universal was 'steal and adapt' Rybka is obviously better than those it is accused of copying. as stated in an earlier post how can 64% overlap be considered anywhere near identical.

and finally the panel of 'judges' were rybka's competitors.


Did you read the link(s)?  It was against the rules.  Also he lied about it.

Serious news...

...so we have yet another "cheat" connected to the chess world...another black eye for chess...

...clearly rules were broken, so he will pay to the hilt...the reason for the "previous WCC" is both to discredit, and provide an avenue to take legal action to recover "stolen" prize money...and this rumour of cloning has been going on for years now...

...how does this affect RYBKA going forward? It opens the door now for legal action to be taken against its creators and distributors for copyright violations...yep, a big can of whip ass has just been opened...
