Other than that, I've been more interested in the implementation of adaptive search; there's a lot of exciting progress there.

Competing for resources etc ., Evolution builds everything it can , and the according to the local boundary contrainsts whittles the things ( read, groups individuals organisms ) down that temporariliy survive, sometimes with the help of cooperation, competition, alliances. Ara 's chain made dog, fits the evolutionary graph theory well. However nature would factor in gravity, temp, rate of decay, redundancy, limited resources You ' ve argued the breakdown of software- hardware, and technology top down , bottom up, I believe the ACTIVE boundary between thing and its environment , mathematics of membrane computing" , sets up the genetic ( Robert Trivers ) chemical , battle , using shannon like error correction augmented in biology by" deceptive symbols." see you friday On Fri, Jul 12, 2013 at 8:14 AM, Neil Gershenfe wrote: Fri 7/19?
