DFA to Regular Expression Conversion using State Elimination Method
Download pdf DFA to Regular Expression What is Deterministic Finite Automata? Deterministic finite automata (or DFA) are finite state machines that accept or reject strings of characters by parsing them through a sequence that is uniquely determined by each string. The term “ deterministic ” refers to the fact that each string, and thus each state sequence, is unique. These machines are called finite because there are a limited number of possible states which can be reached. In practice, DFAs are made up of five components (and they’re often denoted by a five-symbol set known as a 5-tuple). These components include: A finite number of states A set of symbols known as the alphabet, also finite in number A function that operates the transition between states for each symbol An initial start state where the first input is given or processed A final state or states, known as accepting states.
