NP Complete problems/languages. Need to be in NP. Need to be in NP-Hard. If both are satisfied then it is an NP complete problem. Reducibility is a transitive relation. If we know a single problem in NP-Complete that helps when we are asked to prove some other problem is NP-Complete. Assume problem P is NP Complete. All NP problems are NP-complete means: Easy enough to be in NP, but hard enough to be NP-hard. "x is NP-complete" <=> "x is in NP and x is NP-hard". Actually, you can now answer the question without any understanding what NP, NP-complete and so on mean, just from the definitions of NP-hard and NP-complete.

The concept of NP-completeness was introduced in 1971 (see CookвЂ“Levin theorem), though the term NP-complete was introduced later. At the 1971 STOC conference, there was a fierce debate between the computer scientists about whether NP-complete problems could be solved in polynomial time on a deterministic Turing machine. quent years, many problems central to diverse areas of application were shown to be NP-complete (see [GJ79] for a list). If P 6= NP, we could never solve these problems efп¬Ѓciently. If, on the other hand P = NP, the consequences would be even more stunning, since every one of these problems would have a polynomial time solution. The

First, a problem being in NP and a problem being NP-hard are not mutually exclusive. When a problem is both in NP and NP-hard, we say that the problem is NP-complete, as Dave Clarke explained. Second, it is not known (or believed) that all problems in NP can be solved deterministically in time O(2 n), or in time 2 O(n) for that matter. quent years, many problems central to diverse areas of application were shown to be NP-complete (see [GJ79] for a list).

Proving that A Problem is NP-Complete. P roving NP-completeness of a problem involves 2 steps. First we have to show that the problem belongs to NP and then we have to show it is NP-hard. The NP-complete means: Easy enough to be in NP, but hard enough to be NP-hard. "x is NP-complete" <=> "x is in NP and x is NP-hard". Actually, you can now answer the question without any understanding what NP, NP-complete and so on mean, just from the definitions of NP-hard and NP-complete.

The relation between the complexity classes P and NP is studied in computational complexity theory, the part of the theory of computation dealing with the resources required during computation to solve a given problem. The most common resources are time (how many steps it takes to solve a problem) and space (how much memory it takes to solve a problem). NP-hard if all problems in NP polynomially reduce to it; and; NP-complete if all problems in NP polynomially transform to it. What is the difference between polynomial reduction and polynomial transformation? I am unsure what the definition of polynomial reduction means exactly; I had thought the "polynomial time oracle algorithm" would be

tion of NP-completeness around 1971, and gave examples of combinatorial NP-complete problems. They show that, in order to prove P = NP, it sufп¬Ѓces to study a few problems in NP. These problems are supposed to be the вЂњhardestвЂќ problems in NP, and is called NP-complete problems (NPC problems). They further show that a polynomial-time quent years, many problems central to diverse areas of application were shown to be NP-complete (see [GJ79] for a list). If P 6= NP, we could never solve these problems efп¬Ѓciently. If, on the other hand P = NP, the consequences would be even more stunning, since every one of these problems would have a polynomial time solution. The

far outweigh the differences. What is important for patients to know is that, regardless of whether they see a PA or an NP, they are being treated by a highly educated, well-trained healthcare provider who places the patient at the center of their care. The following highlights some of the key differences between PAs and NPs. What is an NP? Can someone please summarize the exact difference between NP-Complete and NP-Hard problems in simple language? Wiki and my standard books aren't exactly helping.
