> I was looking for more than the statement on the classes of rules, and I didn't find the formal explanation Yes. Wolfram gets the point across, but the lack of formality makes the taxonomy appear somewhat arbitrary which leaves one hanging. Thanks for the tip about Ilachinski's book. I notice it was published around the same time as NKS which makes me curious about the overlap in content; it certainly seems to have a more formal approach.

Ilachinski's book cites Wolfram's 1980s article as a pivotal moment on top of the previous history with CA, but he goes into everything - complexity, CA, neural networks, genetic algorithms, etc. It is an amazing book, and I thoroughly enjoy his exposition and breadth of knowledge. I started with neural networks and evolutionary computing back in the late 80s. His book is a great survey book with great detail too. The Artificial War book is pretty cool. I was into war games (board games back in the 80s), and his multi-agent approach was unique at the time and is fun to play with.

  Thanks. It's nice to hear the 80's article was acknowledged. Game theory dynamics are fascinating. I have Nowak's Evolutionary Dynamics in my shelf, in which he covers for instance spatial prisoner's dilemma modelled as cellular automata.

    I have picked up Nowak's book a few times, but I have not read it. Wolfram's new physic's book is visually appealing, and I am starting it soon. I tried making up my own rules without reference to see just how difficult it is to achieve anything similar to Conway's GoL, and it is eyeopening. I do love the variations on it where the simulations look almost like microscope vids of actual organisms. Artificial Life sims. People are getting creative in these sims, and some produce some beautiful and engaging animations.

      The images were always what drew me to NKS, and CA in general obviously. I don't expect to find any answers in them; for me it's a gateway to ontological mysteries. I'm quite content spending time just in wonder.

  That's true. It's a convention. I thirst for an epistemological investigation, in turn, I suppose.

    That's IMO a much more fascinating question. What does it mean that simple systems can exhibit "life"? The first three kinds of simple system are, um, pretty obvious: Boring is static, Oscillators have movement but are static in time so to speak, chaotic systems overwhelm themselves with too much movement, "living" systems seem to balance stasis and chaos. But what does it mean? ;)

      Exactly. Glad we share the same view.
