WebbAs the following theorem shows, NP-completeness is at the crux of deciding whether P is in fact equal to NP. Theorem 34.4: If any NP-complete problem is polynomial-time solvable, then P = NP. Equivalently, if any problem in NP is not polynomial-time solvable, then no NP-complete problem is polynomial-time solvable. Webbis NP-hard.

Sets fargo women\u0027s care centerWebbIntuitively, these are the problems that are at least as hard as the NP-complete problems. Note that NP-hard problems do not have to be in NP, and they do not have to be decision problems. The precise definition here is that a problem X is NP-hard, if there is an NP-complete problem Y, such that Y is reducible to X in polynomial time. But since ... fargo window company

WebbThere are much stronger versions of the P vs. NP conjecture that complexity theorists often take as axioms, and that imply that many problems are not NP-complete. The most standard class of assumptions is the conjecture that the NP hierarchy does not collapse. WebbMany of these problems can be reduced to one of the classical problems called NP-complete problems which either cannot be solved by a polynomial algorithm or solving any one of them would win you a million dollars (see Millenium Prize Problems) and eternal worldwide fame for solving the main problem of computer science called P vs NP.

WebbThe standard way of proving any NP-theorem is to first reduce it to an instance of the aforementioned NP-complete problems, and then conduct the zero-knowledge proof. This question pertains to such reduction. Assume that the P vs. NP is settled in any of the following ways: P = NP P ≠ NP P vs. NP is independent of the standard axiomatic set …

This is a list of some of the more commonly known problems that are NP-complete when expressed as decision problems. As there are hundreds of such problems known, this list is in no way comprehensive. Many problems of this type can be found in Garey & Johnson (1979).
