WebA DFA represents a finite state machine that recognizes a RE. For example, the following DFA: recognizes ( abc+) +. A finite automaton consists of a finite set of states, a set of transitions (moves), one start state, and a set of final states (accepting states). In addition, a DFA has a unique transition for every state-character combination. WebAug 8, 2024 · There can be multiple final states in both DFA and NFA. NFA is more of a theoretical concept.
