Review of "A New Kind of Science"
Reflections on Stephen Wolfram's "A New Kind of Science" by Ray Kurzweil "So how do we get from these interesting but limited patterns of Class 4 automata to those of insects, or humans or Chopin preludes? One concept we need to add is conflict, i.e., evolution. If we add another simple concept to that of Wolfram's simple cellular automata, i.e., an evolutionary algorithm, we start to get far more interesting, and more intelligent results. Wolfram would say that the Class 4 automata and an evolutionary algorithm are "computationally equivalent." But that is only true on what I could regard as the "hardware" level. On the software level, the order of the patterns produced are clearly different, and of a different order of complexity." From Psybertron.
