What is deterministic and nondeterministic Turing machine?
In a deterministic Turing machine, the set of rules impose at most one action to be performed for any given situation. In a nondeterministic Turing machine, it may have a set of rules that prescribes more than one action for a given situation.
Which statement is true about deterministic Turing machines?
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.
What are the types of Turing machine?

What is nondeterministic Turing machine in TOC?
The computation of a non-deterministic Turing Machine is a tree of configurations that can be reached from the start configuration. An input is accepted if there is at least one node of the tree which is an accept configuration, otherwise it is not accepted.
What is deterministic and nondeterministic function?
A deterministic function always returns the same results if given the same input values. A nondeterministic function may return different results every time it is called, even when the same input values are provided.
What is deterministic and non deterministic experiment?
Non Deterministic experiment: A Non deterministic experiment or a random experiment is an experiment for which more than one possible outcomes. Due to uncertainty, outcomes of this experiment does not predicted before performing the experiment.
What are the differences between finite automata and Turing machine?
Finite state machines describe a small class of languages where no memory is needed. Turing Machines are the mathematical description of a computer and accept a much larger class of languages than FSMs do. Finite state machines have lower computational power than the Turing machine.
Under what circumstance does a non deterministic Turing machine output accept?
Lecture : Nondeterministic Turing Machines [Fa’ ] 4 N accepts w if and only if there is at least one sequence of valid transitions from the initial configuration (start,w,0) that leads to the accept state.
What is Turing machine and types of Turing machine?
Turing Machine was invented by Alan Turing in 1936 and it is used to accept Recursive Enumerable Languages (generated by Type-0 Grammar). A turing machine consists of a tape of infinite length on which read and writes operation can be performed.
What are the components of a Turing machine?
A Turing machine consists of (a) a finite control, (b) one tape, representing the memory, that has a left margin and is divided into an infinite number of cells, and (c) a moving read/write head. The finite control can be in any one of a finite set Q of states.
What is the difference between deterministic and nondeterministic?
Which is more powerful deterministic Turing machine or non deterministic Turing machine?
Non-determinism is more powerful than determinism for pushdown automata. But it makes no difference for finite automata. Quite surprisingly, the deterministic and non-deterministic Turing machines are the same in power.
