Detailed explanation-1: -Formally, a DFA is described by a 5-tuple (Q, , , q0, F) in which Q is a finite set of states, is a finite set of input symbols also known as the alphabet, is a state transition function ( : Q × → Q), q0 is the start state (q0 Q), and F is a set of accept states (F Q).

Detailed explanation-2: -A classical CA model in Q defines the transition system with the function of global transitions as . In this model, F(q)t = f(qt−1, qt, qt+1), where denotes the local transition function. To define the global transition function more explicitly, F(q, x) = f((q0, q1, q2), x1).
