Web21 jun. 2015 · If the n -bit automaton has k states, then the corresponding finite-state automaton has 2 n k states. An automaton that stores m binary words each of length n has a total of mn bits of memory, so each state of the mn -bit automaton corresponds to 2 m n states of the corresponding memoryless finite-state automaton.

On b, there is a transition from the accepting state to the non-accepting state. DFAs need all transitions and all states to be complete, unlike NFAs. – Welbog Jul 25, 2024 at 17:07 WebWij willen hier een beschrijving geven, maar de site die u nu bekijkt staat dit niet toe. can i buy a gift card for gas only

WebSo a trap state can be final or non final, since both can have either no transitions defined or have transitions for every symbol happening to itself. A final state cannot be a dead state, as we can read ϵ and stay in the same state, which is final state. But this, seems incorrect, as epsilon moves are not allowed in DFAs.
