A deterministic finite automaton (DFA) is a 5-tuple (Q, Σ, δ, q0, F), whereQ is a finite set called the states; Σ is a finite set called the alphabet; δ: Q x Σ-> Q is the transition function DFA-Simulation Introduction A deterministic finite automaton (DFA)—also known as deterministic finite state machine—is a finite state machine that accepts/rejects finite strings of symbols and only produces a unique computation (or run) of the automaton for each input string. For each input DFA, output a header as follows: DFA #k: where k represents the DFA number, starting at 1. This involves transitioning through states based on the input symbols, following the transition function, until either reaching an accepting state or exhausting the input. The simulation of a deterministic finite automaton (DFA) refers to the process of mimicking the behavior of a DFA on a given input string to determine whether the string is accepted or rejected.
