DB made a "contribution" to chess (not computer chess) by increasing interest. DB hurt CC more than it helped with regard to beating Kasparov. Fortunately their technical contributions were significant.
Bob, DB was the first computer chess hardware/software to beat a World Champion. The match attracted and garnered much attention to computer chess and chess itself. It was probably the second most important chess match behind only the 1972 Fischer v. Spassky match. I actually see the DB match as a major turning point in computer chess. People became less interested in computer chess vs. human tournaments as "It Has All Been Done Before". The match ended the golden age of computer chess, where humans still had a chance to win a match, the golden age is now over. We are now in the modern age where computer chess programs play like Caissa and we are mere mortals
DB did add to computer chess both positive and negative attributes.
Rybka is helping to pull other chess engines along, by being better. It encourages other computer chess authors to improve, both for commercial purposes as well as being the *best*. We all want to win, it is our nature. So Rybka is adding to computer chess knowledge by inspiring others to improve. IMHO Rybka has Fruit code in it and possibly...dare we say..."Crafty Code"
in it?!
It would not surprise me if several of the top commercial and amateur programs have code either cloned or derived from other programs that have open source code. This sharing of ideas, although somewhat under handed *does* help to improve computer chess code. However, I do agree with you that original thinking and creativity will be the *key* to taking even greater strides into the future.
On a side note, I notice I cannot download Crafty for my IPOD, would it be possible to create a Crafty version for IPod, IPad and IPhone? These platforms are going to be the future. Please read the article
