A caveat:
There is enough similarity in some algorithms of Rybka 1.0 that I think it would not be unreasonable for any governing body that chooses to consider Rybka 1.0 a derivative of Fruit and ban it from certain competitions. That would, of course, be up to their judgement.
Dan why would you be against the WCCC judges from performing a derivative test on Rybka 4? It is right in the rules that they are allowed! I mean a real derivative test, not just does R4 make the identical moves as Fruit.

If any other competitor was going to make an official complaint to the ICGA about Rybka it probably should have been done when Rybka 1st entered the WCCC. I doubt they would consider a complaint several years later. Fabien has never complained and Fruit and Rybka have both competed in the same event.
I also doubt that any commercial author would submit their source if asked to.
There is nothing in the rules that says a fellow competitor has to request a derivative test. In addition, if Rybka 4 is not turned over when requested then they are out of the tourney and guess what happens in the Internet rumour mill

I am neither for nor against that. Whatever they choose to do is fine with me.

If you really think they will accept a complaint from a non-competitor then go ahead and make one. I am 100% sure it will be rejected. As for the internet rumour mill a few people on a forum have almost no effect on sales.
I suspect that before asking for the source they would take into account that Fabien says he does not care.

Sure they don't, in the same as appearance of Ippo doesn't have .
Do you really think many customers of Rybka or Fritz have heard of these engines? a few % at most.
Actually this is not a surprise but its good to hear you confirm this Harvey
last year when the Prior mod team made the tough decision to allow links to Ippo... late in their term .. i personally got PM's and Emails foretelling the demise of computer chess as we now know it
Commercial Engine authors would be falling by the way side
we were guilty of taking the food out from the very mouths of their children
as far as i can tell several commercial authors have not only survived but released major upgrades to their engines and we have even seen new commercial engines come on the market

I chose Fritz and Rybka deliberately. I think the effect on those that sell directly on the web is probably very different. Which new commercial engines are you thinking of?

Still no engine authors had to give up and change careers because of our Ippo linkeage ..
but i know your job has been made tougher on the Chessbase server
Rybka's evaluation has been the subject of much speculation ever since its appearance. Various theories have been put forth about the inner workings of the evaluation, but with the publication of Strelka, it was shown just how wrong everyone was. It is perhaps ironic that Rybka's evaluation is its most similar part to Fruit; it contains, in my opinion, the most damning evidence of all.
