Step 4: Stop when Pk = Pk-1 (No change in partition).Step 3: Find Pk by partitioning the different sets of Pk-1.Step 1: We will divide Q (set of states) into two sets.Dumping state also refers to the reject state of the automata. Which of the following will not be accepted by the following DFA? Explanation: All the Strings are getting accepted except ‘ababaabaa’ as it is directed to dumping state. Which string will not be accepted by following DFA? For any NFA, we can construct an equivalent DFA (see below). Explanation: For converting RE to DFA, first we convert RE to NFA (Thompson Construction), and then NFA is converted into DFA(Subset Construction).Ĭan a DFA simulate NDFA? Explanation: Yes it can be done through power set construction.Ī DFA is just a special case of an NFA that happens not to have any null transitions or multiple transitions on the same symbol. It is suitable to use _ method/methods to convert a DFA to regular expression. Any class of an automata can be without a final state! Which method is suitable for conversion of DFA to NFA?Įxplanation: For every NFA, there exists an equivalent DFA and vice versa.

If an automata is not acceptor but transducer then final state is not needed. From each state on a given input symbol the automaton may proceed into one possible next state.

A Finite Automata(FA) is said to be non deterministic, if there is more than one possible transition from one state on the same input symbol….Difference between DFA and NFA : SR.NO.Ĭan a DFA recognize a palindrome number? Explanation: Language to accept a palindrome number or string will be non-regular and thus, its DFA cannot be obtained.ĭFA – Deterministic finite automaton – is a finite state machine that produces a unique computation for each input string. NFA refers to Nondeterministic Finite Automaton. What is the relation between NFA and DFA?

Yes, every DFA can be converted (and actually trivially is) an NFA.

7 What’s the difference between a NFA and a FA?.

5 Which string will not be accepted by following DFA?.

4 Which method is suitable for conversion of DFA to NFA?.

2 What is the relation between NFA and DFA?.

PrerequisitesĪ step by step series of examples that tell you how to get a development env running. These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. Progrssive Web APP (PWA) designed to accept the input about the states and transtions of a Non-Deterministic Automata (NFA) and to convert it into an equivalent Deterministic Finite Automata (DFA) and visualize it.
