NP-Hard are problems that are at least as hard as the hardest problems in NP. Note that NP-Complete problems are also NP-hard. However not all NP-hard problems are NP (or even a decision problem), despite having NP as a prefix. That is the NP in NP-hard does not mean non-determi...
At the undergraduate level, students should learn at least enough complexity to understand the difference between P, NP, NP-Hard and NP-Complete. To avoid leaving the wrong impression, students should solve a few large problems in NP by reduction to SAT and the use of modern SAT solvers. Re...

I'm not going to explain all the terms I already used like NP and NP-complete. But I will explain why the P≠NP is important. Since it is not yet proven, this comes down to the fact that nobody knows whether problems that can be verified quickly can also be solved quickly. In thi...
An NP-complete problem is one that is in NP and exhibits a special property: if you could find a polynomial-time algorithm to solve it, you could solve all problems in NP in polynomial time. In essence, NP-complete problems are “hardest” in NP because they are at least as hard as ...
into the NPCD system for those individuals with persistent symptoms who are referred and/or seen by the specialty programs for care, it is unclear whether those individuals who have sustained a TBI but have had complete resolution of symptoms are consistently recorded for this exposure in the ...
Fibre Channel and SANs have made all of these “what ifs” possible, including many others that will be discussed in later chapters. SANs are making backups more manageable than ever—regardless of the size of the servers being backed up. In many cases, SANs are making things possible that...
NP-hard problems are those at least as hard as NP problems; i.e., all NP problems can be reduced (in polynomial time) to them. ... If any NP-complete problem is in P, then it would follow thatP = NP. However, many important problems have been shown to be NP-complete, and no...
aOf course the indictment of being an NP-Complete problem does not mitigate our requirement to look for some way deal with it. In what follows, we examine, in an introductory manner, a few results. 当然控告是一个NP完全问题不缓和我们的要求寻找某一方式成交以它。 在什么跟随,我们审查,以介绍方...
