Cellular Automata (CAs) are dynamical systems in which space and time are discrete, where each cell obeys the same rule and has a finite number of states. The Cellular Automata model is both general and simple. Generality relates to two things: (1) the model can perform universal computation and (2) the basic units are formed out of a general interaction and not because of a specialized function. The Cellular Automata model is one of the simplest and most general models available for observing and computing complex systems. In this paper we provide an in-depth snapshot of CA, its components that...
