Are computers non-deterministic?

Digital computers are completely deterministic; their state at any time is uniquely predictable from the input and the initial state.

Are non-deterministic Turing machines more powerful?

Non-determinism is more powerful than determinism for pushdown automata. Quite surprisingly, the deterministic and non-deterministic Turing machines are the same in power. Note: If a nondeterministic Turing machine accepts a language L, then there is a deterministic Turing machine that also accepts L.

What does it mean for computers to be 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.

How can you identify a deterministic Turing machine from a non deterministic Turing machine?

The machine is said to be deterministic if there is only one possible action at each step. It is said to be nondeterministic if there are finitely many possible actions at each step. Some states are distinguished and called accepting states and one state is distinguished and called the initial state.

What makes a machine deterministic?

Formal definition If the machine is deterministic, this means that from this point onwards, its current state determines what its next state will be; its course through the set of states is predetermined. Note that a machine can be deterministic and still never stop or finish, and therefore fail to deliver a result.

Which of the following is not allowed in deterministic Turing machine?

5. Which of the following is not a Non deterministic turing machine? Explanation: A read only turing machine or 2 way deterministic finite automaton is a class of model of computability that behaves like a turing machine, and can move in both directions across input, except cannot write to its input tape. 6.
