- This occurs in cellular automata if you have an infinite state space;
- e.g., if you state space is the set of all right half infinite 0,1
- sequences (this is my favorite), and it is known that some cellular
- automata are equivalent to Turing machines.
- Lots of references abound, but you might check Physica D 45 (1990)
- where the entire issue is devoted to CA's. It gives lots of good
- references to past literature as well.
