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. WebIn DFA, there is only one path for specific input from the current state to the next state. DFA does not accept the null move, i.e., the DFA cannot change state without any input character. DFA can contain multiple final …

WebJan 20, 2024 · The DFA’s start state is the set of all possible starting states in the NFA. This set is called the “epsilon closure” of the NFA’s start state. The epsilon closure is the set of all states that can be reached from the … Web1 Answer Sorted by: 3 Yes, every state can be accepting.
