Can a Turing machine compute anything?
The Turing machine can compute anything that can be computed. It is the very definition of computation and the fundamental tool for reasoning about computers.
Are there any things that your laptop can do that a Turing machine Cannot Are there any things that a Turing machine can do that your laptop Cannot?
Short answer is no; modern computers cannot do things that Turing machines can’t do. What they can do is run very sophisticated, complex Turing machines that simulate things that Turing machines would not be able to do.
Can a Turing machine reject a palindrome?
If you find a position where the symbols are different, the input is not a palindrome and you halt-reject. If you get to the end (first blank symbol on the end) without finding a mismatch then it is a palindrome and you halt-accept.
Which of the following is NOT a non 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.
Can Turing machine be simulated by a general purpose computer?
Turing machines can be efficiently simulated by the General Purpose Analog Computer. The Church-Turing thesis states that any sufficiently powerful computational model which captures the notion of algorithm is computationally equivalent to the Turing machine.
Are modern day computers Turing machines?
Turing machines are equivalent to modern electronic computers at a certain theoretical level, but differ in many details. A Turing machine consists of a line of cells known as the “tape”, together with a single active cell, known as the “head”.
Are modern PCS Turing machines?
No. Modern computers are most notably bounded by finite memory.
How can you identify a palindrome using a Turing machine?
Step-1: We start with Q0 state if we get a symbol “a” as input then there should also be “a” at the ending of the string then only the string is palindrome and we have to verify that. We first make the current input “a” to B blank and go to state Q1 move rightwards to traverse the string till we reach the end.
Under what circumstance does a non deterministic Turing machine output accept?
An NTM accepts an input string if and only if at least one of the possible computational paths starting from that string puts the machine into an accepting state.
