Are deterministic Turing machines Decidable?

Are deterministic Turing machines Decidable?

Definition (reminder): A language is decidable if some deterministic Turing machine decides it. Definition (reminder): A language is decidable if some deterministic Turing machine decides it. Theorem: A language is decidable if and only if there is a non-deterministic Turing machine that decides it.

What are the limits of Turing machines?

a. A limitation of Turing machines is that they do not model the strengths of a particular arrangement well. b. For instance, modern stored-program computers are actually instances of a more specific form of abstract machine known as the random access stored program.

Is Turing machine deterministic?

Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm and is particularly useful in explaining the functions of a CPU inside a computer. In a deterministic Turing machine, the set of rules impose at most one action to be performed for any given situation.

Which statement is true about deterministic Turing machine?

Explanation: A deterministic turing machine is unambiguous and for every input, there is exactly one operation possible. It is a subset of non-deterministic Turing machines. 9.

Is a Turing machine non-deterministic?

In theoretical computer science, a nondeterministic Turing machine (NTM) is a theoretical model of computation whose governing rules specify more than one possible action when in some given situations. NTMs are sometimes used in thought experiments to examine the abilities and limits of computers.

What makes a machine deterministic?

In mathematics, computer science and physics, a deterministic system is a system in which no randomness is involved in the development of future states of the system. A deterministic model will thus always produce the same output from a given starting condition or initial state.

Are Decidable languages closed under complement?

– Decidable languages are closed under complementation. To design a machine for the complement of a language L, we can simulate the machine for L on an input. If it accepts then accept and vice versa. – Turing recognizable languages are not closed under complement.
