Code: Select all

Mark A. Lemley, a Stanford law professor who specializes in science and technology issues, wrote in an e-mail that because Fruit and Crafty are freely available may mean that Mr. Rajlich is not guilty of misconduct if he copied some of the code. But, Mr. Lemley added, “I can see why the Computer Gaming Association might want to prohibit it under its rules.”

Guy spoke without knowing what he was talking about. Crafty and Fruit are not "free software". They both have licenses. Which makes _all_ the difference in the world.
It is possible the reporter asked the question in a way suggesting Crafty and Fruit were public domain, because the GPL is quite clear. But then I would expect "a Stanford law professor who specializes in science and technology issues" to do a little home work before responding in an email. Or maybe he really meant what he said...

Sounds like legal-speak to me. "not guilty of misconduct... yet I can see why ICGA..." Aren't those two statements somewhat at odds with each other? If he can see why the ICGA reacted, doesn't that imply misconduct according to their rules? If he doesn't see misconduct, then how could the ICGA reaction be reasonable? I interpret this to be intentionally vague and confusing, because both sides of that statement can't possibly be true.

“In my opinion, there was reasonable basis for the disqualification of Rybka 1 and any tournament victories that occurred within a year or so of its release,” Mr. Kaufman wrote. “By the time Rybka 3 came out, it was for all practical purposes a completely new program,” he said."
Just to enlarge upon the second half here -- some of the Panel did indeed feel the same regarding Rybka 3 [though no investigatory evidence was specifically adduced], and in some sense the disqualifications of Rybka for 2008-10 (and/or the recommendation of this in the Panel report -- though not everyone agreed, and as I say elsewhere, any punishment would be a Board matter) were probably based as much on "manifestations of disrespect" toward the ICGA [in particular, refusing to participate at any stage in the process] as anything else.

If Rajlich's brief sentences of email had bothered to include even something minimal, such as a simple and direct: I specifically think that there is no possible Fruit issue for Rybka 3 and later, as Larry Kaufman rewrote the evaluation from scratch, the verdict for the later years might have been different.

Looks as if the ICGA is on the ball with their re-writing of history:

I thought for the record some of the Levy - Rajlich emails should be included. Here is one from about half way through the investigation an another from when Levy sent Rajlich the Secretariat report. There were several others, and at every turn Levy asked (almost begged_ Rajlich to join the wiki and put up a defense. The only vague defensive remark he made was citing some games where Rybka made different moves than Fruit, which is pretty much meaningless.

Rybka_FruitMar11.pdf was attached
The main wiki Rybka-Fruit Controversy page was attached
A list of questions from the panel members was attached. None of these were ever answered by Rajlick

another email:

13 May 2011:
Hi Vas,

The ICGA investigation panel has completed its investigation and the report of the panel's Secretariat is attached.

Up to now you have not responded positively to my invitations to respond to the various allegations that have been made against you during the course of this investigation. I am now requesting you to do so. You will find all of the linked documents referred to in the report available to you on the wiki, for which you need to register if you wish to read those documents.

In due course the ICGA will consider the attached report, together with any defence, counter-evidence or pleas for mitigation that you may care to offer. Anything that you wish the ICGA to take into consideration when doing so must reach me not later than one month from today, i.e. June 14th.

I should emphasize here that the ICGA is interested only in one question, namely whether or not you violated the ICGA tournament rules by failing to declare the true provenance of Rybka in your entry form submissions for the various World Computer Chess Championships in which the program participated.

I look forward to hearing from you.

Kind regards,

David Levy
The Secretariat final report was attached

After some followup emails, Levy sent this and here was the response:

Hi David,

I'll probably address that stuff a little bit later.

Best regards,
Vas

Note he never did address anything.

I can't say it's my cup of tea, but ChessVibes now has a cartoon up: http://www.chessvibes.com/cartoons/rybbedka/

Well, no one can argue that he was left out of the loop... I assume that he's busy working on a fat contract with ChessBase for Cloud Rybka and simply couldn't care less.

That excuse doesn't pass the "smell" test. Nobody would want the ICGA to label them as a cheater if there was any way to avoid it. But if it is hopeless, then silence is better as it blows over that much sooner..

I agree that it's unbelievable. On the other hand, if he has decided that his financial future has nothing to do with consumer sales, and everything to do with corporate sales, to corporations which don't care if he copied code... (e.g. Silver and Friedel were on the panel, Chessbase news has yet to mention to story). I'm just speculating, though.
