Test: Non Deterministic Turing Machines - Computer Science Engineering (CSE) MCQ

Turing machine is known as universal computer. It is denoted by M=(Q,Σ,Ґ ,δ ,q0, B,F)

A turing machine can have many applications like : Enumerator (A turing machine with an output printer), function computer, etc.

The following mentioned is the difference between 2-way FA and TM. Another instance is that TM has a read/write tape head while FA doesn’t.

The following mentioned are the only possibilities of operating a string through a turing machine.

Except Recursion, all the other options are techniques of Turing Machine construction which further includes, Checking off symbols and Storage in finite control.

 All of the mentioned are correct statements for a two way infinite tape turing machine. Theorems say the power of such a machine is in no way superior than a standard turing machine.

A turing machine can be used as a transducer. The most obvious way to do this is to treat the entire non blank portion of the initial tape as input, and to treat the entire blank portion of the tape when the machine halts as output.

If the tape contains k-dimentional array of cells infinte in all 2^k directions, for some fixed k and has a finite control, the machine can be called Multidimentional TM.

Here, the turing machine can use the printer as an output device to print strings.
Note: There is no input to an enumerator. If it doesn’t halt, it may print an infinite set of strings.

An enumerator is a turing machine with an output printer. It can use an printer as an output device to print output strings. As n also holds the value , epsilon will also be a part of the output set.
