{wiki=Aperiodic_finite_state_automaton}
An **aperiodic finite state automaton (AFSA)** is a type of finite state automaton (FSA) that possesses certain structural characteristics related to the periodicity of its states. In the context of automata theory, the concept of periodicity has to do with the behavior of the automaton as it processes inputs.
