Which is more powerful deterministic Turing machine or nondeterministic Turing machine?
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.
Are non deterministic Turing machines faster?
For the most important class of problem in computer science, non-deterministic polynomial complete problems, non-deterministic UTMs (NUTMs) are theoretically exponentially faster than both classical UTMs and quantum mechanical UTMs (QUTMs).
What is deterministic and non deterministic?
The algorithms in which the result of every algorithm is uniquely defined are known as the Deterministic Algorithm. On other hand, the algorithms in which the result of every algorithm is not uniquely defined and result could be random are known as the Non-Deterministic Algorithm.
Is nondeterministic Turing machine equivalent to deterministic Turing machine?
Every nondeterministic Turing machine has an equivalent deterministic Turing Machine. Timeshare a deterministic TM to different branches of the nondeterministic computation!
Which is more powerful NTM or DTM?
It might seem that NTMs are more powerful than DTMs, since they can allow trees of possible computations arising from the same initial configuration, accepting a string if any one branch in the tree accepts it. However, it is possible to simulate NTMs with DTMs, and in fact this can be done in more than one way.
Are quantum computers non deterministic Turing machines?
So, quantum Turing machines are a model of computation which is not deterministic, but which is different from a “nondeterministic Turing machine”.
Is quantum computer a non deterministic Turing machine?
How does non deterministic Turing machine work?
In a Non-Deterministic Turing Machine, for every state and symbol, there are a group of actions the TM can have. If all branches of the computational tree halt on all inputs, the non-deterministic Turing Machine is called a Decider and if for some input, all branches are rejected, the input is also rejected.
