Oct 31, 2023 · Learn the concepts and properties of deterministic and non-deterministic finite automata, two types of finite state machines. Compare and contrast their transition functions, accept states, space requirements and conversion methods with examples.
Difference Between NFA and DFA: If any machine reads an input string one at a time then, any finite automata is called DFA whereas, when there are multiple paths for specific input from the current state to the next state then it is called NFA.

The acronym DFA stands for Deterministic Finite Automaton. It is said that a Finite Automata (FA) is deterministic if, for each input symbol, there is a single output state, i.e., just one transition. A finite deterministic automaton consists of five tuples expressed as, Where, Q: A non-empty finite set of states in the finite control(qo, q1, q2, …...
NFA denotes Nondeterministic Finite Automaton. It is argued that a Finite Automata (FA) is non-deterministic if there are several alternative transitions from one state to the next for the same input symbol. A non-deterministic finite automaton is alternatively expressed as a collection of five tuples. Where, Q: A set of non empty finite states. ?:...

1. Are NFA and DFA equal?
Every DFA has an equivalent NFA. (Proof by construction - trivial.) Given N = (Q,?, ?, q0,F), NFA recognizes some language A. We prove that every NFA has an equivalent DFA by showing how to construct a DFA N from N that recognizes the same language A.
2. Why every NFA is not DFA?
Each NFA is not identical to the DFA, but each NFA may be translated into the DFA. NFA is defined in the same manner as DFA, except that it includes numerous subsequent states and transitions.
3. Can a DFA have no states?
Yes Possible. If an automaton is not an acceptor but a transducer, there is no requirement for a final state. Any kind of automaton may be devoid of a final state!
