You probably should go to http://talkchess.com/forum/index.php and make a search. This question have been discussed a lot there by engine developers. New discussions about the subject is restricted to a subforum that is only accessible to registered members so you should register there if you want to follow the current discussion.

In short, I think the consensus is that the ippolito family of engines are not based on the source code of Rybka but have obtained parts of Rybka through reverse engineering. So it's not a clone but probably have to thank its strength to morally questionable means. This morally questionable status of the engine is the reason many tournaments do not include it.

Some tournaments might not include Robbolito because they require that the author(s) of a participating engine is known. The Ippolito source code came from anonymous authors and does not fill the requirements.

If you are not satisfied with the situation, it is of course possible the make your own tournament and publish the results on the web

Hi Hans !

Do you think all Robbolito/Iggorit/Ippolit family enginees are based on Rybka 2.2 source code? They are much stronger than Rybka 2.2 and Rybka 3 even.  I have read in some other forums that Robbolito may be based on a stolen source code from Rybka beta version between 3 and 4.

Sorry for my English

Hi Peter,

Yes many Rykba clones now a days
The source of Rykba 2.2 where on the internet
Even the latest Fritz! plays 80% of the moves of Rykba now a days!
This info i did get of Jeroen Noomen and he has a point if u see the newest fritz with the version before,look at the elo

Kind regards,Hans

Hi Peter
The obvious answer is that the people who produce the rating lists either think that it is one of the many new Rybka clones and will therefore not recognise it as a legal piece of software or maybe if they do then not enough test games have been played. Maybe you should contact the rating list producers for the reason.

Hi.

My name is Peter. I'am from Poland, I'd like to ask you why Robbolito and his clones are not included in any computer chess rating list for example CEGT. Many people know that Robbolito is the strongest chess
engines of the world but nobody say it publicly.
Thanks
