WebJul 16, 2024 · Short version: All problems that can be quickly verified by a classical computer once a solution is given. Precise version: A problem is in NP if, given a “yes” answer, there is a short proof that establishes the answer is correct. If the input is a string, X, and you need to decide if the answer is “yes,” then a short proof would be ... Web如果所有pspace中的问题都可以多项式时间归约到某个问题,那么,这个问题可以被定义为pspace难。. 一种语言b为pspace完全,如果它在pspace中,并且为pspace难,即 , 其中, 指的是存在从a到b的多项式时间归约。 pspace完全问题对于研究pspace中的问题非常重要,因为它们代表了pspace中最困难的问题。

WebMar 4, 2024 · In computational complexity theory, the complexity class FNP is the function problem extension of the decision problem class NP. The name is somewhat of a misnomer, since technically it is a class of binary relations, not functions, as the following formal definition explains: WebIn computational complexity theory, a problem is NP-complete when: It is a decision problem , meaning that for any input to the problem, the output is either "yes" or "no". …
WebFeb 2, 2024 · NP-complete problems are the hardest problems in the NP set. A decision problem L is NP-complete if: 1) L is in NP (Any given solution for NP-complete problems can be verified quickly, but there is no efficient known solution). 2) Every problem in NP is reducible to L in polynomial time (Reduction is defined below). WebComplexity Theory 102 FNP and FP A function which, for any given Boolean expression ˚, gives a satisfying truth assignment if ˚ is satis able, and returns \no" otherwise, is a witness function for SAT. If any witness function for SAT is computable in polynomial time, then P = NP. If P = NP, then for every language in NP, some witness function is
NP contains all problems in P, since one can verify any instance of the problem by simply ignoring the proof and solving it. NP is contained in PSPACE—to show this, it suffices to construct a PSPACE machine that loops over all proof strings and feeds each one to a polynomial-time verifier. Since a polynomial-time machine can only read polynomially many bits, it cannot use more than polyn… WebFeb 2, 2024 · NP-completeness applies to the realm of decision problems.
