Difference between DTIME and E (complexity)

DTIME vs. E (complexity)

In computational complexity theory, DTIME (or TIME) is the computational resource of computation time for a deterministic Turing machine. In computational complexity theory, the complexity class E is the set of decision problems that can be solved by a deterministic Turing machine in time 2O(n) and is therefore equal to the complexity class DTIME(2O(n)).

Similarities between DTIME and E (complexity)

DTIME and E (complexity) have 5 things in common (in Unionpedia): Complexity class, Computational complexity theory, Decision problem, EXPTIME, Turing machine.

Complexity class

In computational complexity theory, a complexity class is a set of problems of related resource-based complexity.

Computational complexity theory

Computational complexity theory is a branch of the theory of computation in theoretical computer science and mathematics that focuses on classifying computational problems according to their inherent difficulty, and relating those classes to each other.

Decision problem

In computability theory and computational complexity theory, a decision problem is a question in some formal system with a yes-or-no answer, depending on the values of some input parameters.

In computational complexity theory, the complexity class EXPTIME (sometimes called EXP or DEXPTIME) is the set of all decision problems solvable by a deterministic Turing machine in O(2p(n)) time, where p(n) is a polynomial function of n. In terms of DTIME, We know and also, by the time hierarchy theorem and the space hierarchy theorem, that so at least one of the first three inclusions and at least one of the last three inclusions must be proper, but it is not known which ones are.

Turing machine

A Turing machine is an abstract "machine" that manipulates symbols on a strip of tape according to a table of rules; to be more exact, it is a mathematical model that defines such a device.
