Equivalence of NFA and DFA. + Closure Properties. Lecture 5. October 31, c Haythem O. Ismail. Are DFAs and NFAs Equivalent. It turns out DFAs and NFAs accept exactly the same languages. To show this we must prove every DFA can be converted into.

Scott Dec 14 ’11 at I would think that the power set construction is more straightforward that any algorithm that can routinely convert a regular expression to a DFA. Eqyivalence for the answer: For og formal proof of the powerset construction, please see the Powerset construction article. Home Questions Tags Users Unanswered. However, “the next state of an NFA depends not only on the current input event, but also on an arbitrary number of subsequent input events.

### automata – Can _any_ NFA be converted to a DFA? – Mathematics Stack Exchange

Until these subsequent events occur it is not possible to determine which state the machine is in”. For example, the powerset ndca check out this link and google:. Sign up using Facebook.

How would one prove it? Download our mobile app and study on-the-go. This language is a regular language. Mathematics Stack Exchange works best with JavaScript enabled. Is that even remotely correct?

When the last input symbol is consumed, the NFA accepts if and only if there is some set of transitions that will take it to an accepting state. The establishment of such equivalence is important and useful. It is easier to check membership in DFA but it is more difficult to construct.

Equivqlence nondeterministic finite automaton NFAor nondeterministic finite state machine, does not need to obey these restrictions.
