Hi, Jochen. I don't think I would agree with that statement, but I may not be understanding your terms. I assume not "knowing" the low level system means not having a clear definition. Can you have some sort of fitness function on the high level system, so that the low level definition emerges to produce the high-level patterns? Is this what nature does ... creating an environment with no "program" on the low level system, allowing whatever patterns can best take advantage of it?
Just my thoughts. Cheers, Ted On Thu, Feb 12, 2009 at 3:52 PM, Jochen Fromm <[email protected]> wrote: > Interesting article.
