Describe how the universal Turing machine locates a particular instruction on its description tape
Homework Answers
Turing Machine:
It is abstract computational device which for idealizing the
mathematical calculatios.it contains the line of cells called tape
that move backward and forward.An active element is know as Head
that possesses the property called State. Turing machine was
invented by Alan Turing.
How turing machine locates the instruction:
There is Intruction table which contains the finite collection of
instructions, each instruction is designed for particular
operations.
If the current state of turing machine is K and the symbol under
head is Q, it will search the instruction table for the particular
state and will perform the operation based on the instruction
table.

Describe the computational power of a single tape Turing machine compared to a nondeterministic single tape Turing machine. In particular, discuss the time complexity of a single tape Turing machine that simulates a single tape nondeterministic Turing machine. Is the difference exponential or polynomial? . .

Describe a Turing Machine that will read its input tape as a binary number n and produce on its tape the binary representation of n + 1. That is, the TM will be a subprogram that will add one to an input number. This description could be a formal TM that does what is asked. It could also be slightly less than totally formal provided it is crystal clear what is happening.

A Turing machine with doubly infinite tape (TMDIT) is similar to an ordinary Turing machine except that its tape is infinite to the left as well as to the right. The tape is initially filled with blanks except for the portion that contains the input. Computation is defined as usual except that the head never encounters an end to the tape as it moves leftward. Show that the class of languages recognized by TDMITs is the same as the class...

Introduce a Turing machine to decide the languages to follow. You must Algorithmic description, but with a sufficient level of detail. You can use the variants of the original model of the Turing machine. {w w^R w | where w is a word formed by 0's and 1's} {w ∈ {a, b}∗| w is a palindrome and has the same number of a's and b's}. Please describe which variant of Turing whether it is with a tape or multi tape....
