What computations can CA do?
Contributions by: Benedict.M.Wightman@cm.cf.ac.uk If you just want a CA that does !gates then ‘Wireworld’, a CA that simulates ‘electron streams’ is probably an easier starting point than Conway’s Life that exhibits the same level of computational complexity, just on a more manageable scale. It’s in the CA Lab (Rudy Rucker’s PC-based CA package), but the rules are fairly simple and it may well be elsewhere too. Cellular-3.0 includes WireWorld as an example.
