PDF	Nondeterministic Finite Automata In a nondeterministic finite automaton (NFA) for each state there can be zero one two or more transitions corresponding to a particular symbol

In particular, every DFA is also an NFA.
Sometimes the term NFA is used in a narrower sense, referring to an NFA that is not a DFA, but not in this article.
Using the subset construction algorithm, each NFA can be translated to an equivalent DFA; i.e., a DFA recognizing the same formal language.

What is DFA and NDFA?

DFA stands for deterministic finite. automata.
NDFA stands for non-deterministic. finite automata.

What is NFA in automata with example?

NFA (Non-Deterministic finite automata) NFA stands for non-deterministic finite automata.
It is easy to construct an NFA than DFA for a given regular language.
The finite automata are called NFA when there exist many paths for specific input from the current state to the next state.

What is non-deterministic finite automata explain?

Previous.
In NDFA, for a particular input symbol, the machine can move to any combination of the states in the machine.
In other words, the exact state to which the machine moves cannot be determined.
Hence, it is called Non-deterministic Automaton.

A deterministic finite automaton (DFA) can be seen as a special kind of NFA, in which for each state and symbol, the transition function has exactly one state.Formal definition · Example · Equivalence to DFA · PropertiesAutres questions
