Is using three tapes in a multitape TN equivalent to single tape time t2(square) or t3(cube)? In other words is the time complexity directly related to number of tapes?
Using three tapes in a multitape Turing machine (MTM) does not necessarily result in an equivalent time complexity of t2(square) or t3(cube). The time complexity of a computational model is determined by the number of steps required to solve a problem, and it is not directly related to the number of tapes used in the
Is there a class of problems which can be described by deterministic TM with a limitation of only scanning tape in right direction and never going back (left)?
Deterministic Turing Machines (DTMs) are computational models that can be used to solve various problems. The behavior of a DTM is determined by a set of states, a tape alphabet, a transition function, and initial and final states. In the field of computational complexity theory, the time complexity of a problem is often analyzed in

Can a multi-tape Turing machine be simulated on a single tape Turing machine? If so, what is the impact on the execution time?
A multi-tape Turing machine is a theoretical computational model that consists of multiple tapes, each with its own read/write head. It is capable of performing parallel operations on different tapes simultaneously. On the other hand, a single tape Turing machine has only one tape and can only perform operations sequentially. The question at hand is
How does using a multi-tape Turing machine improve the time complexity of an algorithm compared to a single tape Turing machine?
A multi-tape Turing machine is a computational model that extends the capabilities of a traditional single tape Turing machine by incorporating multiple tapes. This additional tape allows for more efficient processing of algorithms, thereby improving the time complexity compared to a single tape Turing machine. To understand how a multi-tape Turing machine improves time complexity,
