What happened then?

Fabien.

We found _lots_ of similarities. Zach created a web page that went into great detail with the analysis. There are some obvious differences between Fruit and Rybka, but there are a _ton_ of similarities. Too many to be pure luck.

But these similarities are not a proof of code copying.

Sven

If you look at my previous comments, "similarity" is "identical code". The entire program was not copied. But large chunks were. That _is_ proof of code copying...

Since large chunks were copied, but not everything, I chose to not say "identical" to be accurate. But they are _very_ similar. Moreso when you factor out the bitboard changes...

Just one question Bob. What happens if this case is tried by the FSF (and I hope it is because we all want to see the matter resolved with some finality), and Vas is cleared?

Cheers,
Graham.

It's rather simple.
Take all your programs zip it in a file (I seriously doubt there would be more than 100MB size in total) and encrypt with like AES256 and then send it to yourself on IMAP account (divide a file if necessary and test everything if it works).

I really don't see how that is unreliably or breakable or hackable (unless you lose the key, but that's another issue)...

The issue is, "where is that file stored?" If it is on my office box, I have complete control, and my office machine has never been broken into. If it is on gmail, there is no guarantee of any such protection for privacy, which is a requirement for my email account due to FIRPA, HIPA and such. So gmail is out. And the machine in my office is the same machine where the program copies exist.

BTW, each version of Crafty is maybe a meg. There are thousands of intermediate versions, or gigabytes of data...

All this infor or most of it has been beaten to death before. What can
he do. Its about 5 years to late.
These posts were fun to read. They have done more to promote
IH and Houdini than anything else. Now Houdini is on more rating list
and on Playchess. Also top GM are now using Houdini.

Best,
Gerold

Please give me a second to disagree. Houdini is so to speak the genuine version of Rybka for the average chessplayers and testers of chessless automats, while the greatest chessplayer on Earth, the Cluster Rybka is reserved for the eager elites, talents and professionals in chess.

So, if you want to know the truth about chess, go for the online cluster Rybka. If you like to fiddle in your closet with your own hardware but a weaker program, then you can do business as usual.

As the saying goes, every pot finds a black cattle.
