Test: Multitape Turing Machines - Question 1

A turing machine with several tapes in known as:

Detailed Solution for Test: Multitape Turing Machines - Question 1

A multitape turing machine is an ordinary turing machine with multiple tapes. Each tape has its own head to control the read and write.

Test: Multitape Turing Machines - Question 2

 A multitape turing machine is ________ powerful than a single tape turing machine.

Detailed Solution for Test: Multitape Turing Machines - Question 2

The multitape turing machine model seems much powerful than the single tape model, but any multi tape machine, no matter how many tapes, can be simulated by single taped TM.

Test: Multitape Turing Machines - Question 3

In what ratio, more computation time is needed to simulate multitape turing machines using single tape turing machines?

Detailed Solution for Test: Multitape Turing Machines - Question 3

Thus, multitape turing machines cannot calculate any more functions than single tape machines.

Test: Multitape Turing Machines - Question 4

Which of the following is true for two stack turing machines?
a) o
b)
c)
d

Detailed Solution for Test: Multitape Turing Machines - Question 4

 Two-stack Turing machines have a read-only input and two storage tapes. If a head moves left on either tape a blank is printed on that tape, but one symbol from a “library” can be printed.

Test: Multitape Turing Machines - Question 5

Which of the following is not a Non deterministic turing machine?

Detailed Solution for Test: Multitape Turing Machines - Question 5

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.

Test: Multitape Turing Machines - Question 6

Which of the turing machines have existential and universal states?

Detailed Solution for Test: Multitape Turing Machines - Question 6

ATM is divide into two sets: an existential state is accepting if some transitions leads to an accepting state; an universal state is accepting if every transition leads to an accepting state.

Test: Multitape Turing Machines - Question 7

 Which of the following is false for Quantum Turing machine?

Detailed Solution for Test: Multitape Turing Machines - Question 7

 ‘Is a universal quantum computer sufficient’ is one of the unsolved problem from physics.

Test: Multitape Turing Machines - Question 8

A deterministic turing machine is:

Detailed Solution for Test: Multitape Turing Machines - Question 8

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.

Test: Multitape Turing Machines - Question 9

Which of the following is true about Turing’s a-machine?

Detailed Solution for Test: Multitape Turing Machines - Question 9

Turings a- machine or automatic machine was left ended,right end infinite.Any of finite number of tape symbols were allowed and the 5 tuples were not in order.

Test: Multitape Turing Machines - Question 10

 Which of the following is a multi tape turing machine?

Detailed Solution for Test: Multitape Turing Machines - Question 10

An oblivious turing machine where movements of various heads are fixed functions of time, independent of the input. Pippenger and Fischer showed that any computation that can be performed by a multi-tape Turing machine in n steps can be performed by an oblivious two-tape Turing machine in O(n log n) steps.
