Have you tried looking for it? Or are you one of those people who stand in the middle of the room and shout when they can't find things?

Yes, but thanks for the concern about assertions your side makes. You can now expect the same response from me---> "Go find it yourself."

1. I have looked at the original Sci Am article--no one provided me a link. I searched for it and found it without help from anyone here.
2. I read the article searching for evidence supporting the statement. Nothing apparent in the article.
3. I searched the two links given in the article, www.genetic-programming.com and www.genetic-programming.org,(though not exhaustively) for such evidence. None apparent.
4. I searched the home page of Koza and other of pages for such evidence. None apparent.
5. I searched the patent database for Koza, PID, and cubic function. Found lots of Koza, lots of PID and lots of cubic function, but no evidence for either a granted patent for an evolved PID as someone else asserted nor evidence of any evolved cubic function.

Now just how much have you or anyone else here pursued the topic?

Liar. The Scientific American link was post #504. Sorr it wasn't directed specifically at you, but it was widely discussed.

You can't read the article on the web unless you are a SciAm subscriber, and if you are, you would have seen it in the print version.

Did we not establish days ago that the patent in question was pending?

Are you not aware that pending patent applications cannot be searched, only granted patents?

Didn't several people suggest that you e-mail the researchers and ask them directly?
