Deterministic turing machine
WebTools. In computational complexity theory, the complexity class NEXPTIME (sometimes called NEXP) is the set of decision problems that can be solved by a non-deterministic … WebNDTM is one of many variants of turing mahcine. For example, the classical (deterministic) Turing machine can be equipped with multiple heads and tapes, randomness or quantum states. It can also be constrained by a limited alphabet, limited tape or pre-determined head-movements (see here ).

WebA formal definition. A non-deterministic turing machine is 6-tuple, that is M= (Q, X, ∑, δ, q0, B, F) where; Q is a finite set of states. X is the tape alphabet. ∑ is the input alphabet. δ is a transition function. q0 is the initial state. B is the blank symbol. F is the set of final states.
