Witryna13 wrz 2010 · As noted in the earlier answers, NP-hard means that any problem in NP can be reduced to it. This means that any complete problem for a class (e.g. … Because of the many important problems in this class, there have been extensive efforts to find polynomial-time algorithms for problems in NP. However, there remain a large number of problems in NP that defy such attempts, seeming to require super-polynomial time. Whether these problems are not decidable in polynomial time is one of the greatest open questions in computer science (see P versus NP ("P = NP") problem for an in-depth discussion).
