Parallel Composition of Asynchronous Cellular Automata Simulating Reaction Diffusion Processes

A method of constructing asynchronous cellular automata (ACA) as a parallel composition of two interacting ACA is presented. The resulting ACA is intended to simulate a process with more than one species being involved in it. Two cases of such a composition are considered: (1) when one ACA is functioning independently affecting the evolution of the other, and (2) when both ACA evolute interacting at each iteration.
