WebDec 29, 2024 · The defining characteristic of an NFA is that it can be in multiple states at once. So the “labels” for our new DFA states will actually be a set of the original state labels from the NFA. For example, if we can find an input for which an NFA can simultaneously be in states A and Y , the generated DFA will have a state labeled ${A,Y}$. norfolk registry of deeds dedham maWebThe key lies in the semantics of NFAs. Given a start state and a symbol, a NFA can transition to multiple states. Thus at any given time during a match, a NFA could be in multiple states. And how do we, as humans, match a string on a NFA? We follow it character by character and at each step compute which states the NFA could be in. norfolk reed thatch
