What is non-deterministic finite automata with example?
Advertisements. 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.
What is non-deterministic finite machine?
(definition) Definition: A finite state machine whose transition function maps inputs symbols and states to a (possibly empty) set of next states. The transition function also may map the null symbol (no input symbol needed) and states to next states.
What languages are accepted by deterministic finite automata?
A language L is accepted by a DFA < Q , , q0 , , A > , if and only if L = { w | *( q0 , w ) A } . That is, the language accepted by a DFA is the set of strings accepted by the DFA.
What is the difference between nondeterministic and deterministic finite automata?
DFA refers to Deterministic Finite Automaton. A Finite Automata(FA) is said to be deterministic, if corresponding to an input symbol, there is single resultant state i.e. there is only one transition….Difference between DFA and NFA :
| SR.NO. | DFA | NFA |
|---|---|---|
| 1 | DFA stands for Deterministic Finite Automata. | NFA stands for Nondeterministic Finite Automata. |
Why NFA is non-deterministic?
NFA stands for non-deterministic finite automata. It is easy to construct an NFA when compared to 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. Each NFA can be translated into DFA but every NFA is Non DFA.
What is non-deterministic example?
One example of a non-deterministic algorithm is the execution of concurrent algorithms with race conditions, which can exhibit different outputs on different runs. A non-deterministic algorithm is capable of execution on a deterministic computer which has an unlimited number of parallel processors.

Which one is not an example of finite state machine?
Which of the following language is accepted by a non-deterministic pushdown automata but not by a deterministic PDA?
L can be accepted by ϵ-Non-Deterministic finite automata. L can be accepted by Non-Deterministic Push down automata but not by Deterministic push down automata.
Which of the following machine accepts regular as well as non regular languages?
Explanation: Finite state machine and regular expression have same power to express a language.
What is TOC language?
Languages. A language is a set of string all of which are chosen from some ∑*, where ∑ is a particular alphabet. This means that language L is subset of ∑*. An example is English language, where the collection of legal English words is a set of strings over the alphabet that consists of all the letters.
