Coupling Cellular Automata with Substitution Systems
Coupling Cellular Automata with Substitution Systems
A common phenomenon in natural and man-made systems is that an underlying system will evolve, and periodically its evolution will be altered by an external system. Sometimes these perturbations are random. But at other times, they are the result of some definite structure forming in the underlying evolution. In this Demonstration, we show a minimal version of such deterministic perturbation, where a substitution system affects each step of the evolution of a cellular automaton.
