Exempel på hur man kan använda NP i en mening

• While an NP problem asks whether a given instance is a yes-instance, its complement asks whether an instance is a no-instance, which means the complement is in co-NP.
• Ideologically a social conservative and an economic liberal, he led the National Party (NP) from 1989 to 1997.
• In computational complexity theory, NP (nondeterministic polynomial time) is a complexity class used to classify decision problems.
• In computational complexity theory, the complexity class #P (pronounced "sharp P" or, sometimes "number P" or "hash P") is the set of the counting problems associated with the decision problems in the set NP.
• However, the opposite direction is not true: some problems are undecidable, and therefore even more difficult to solve than all problems in NP, but they are probably not NP-hard (unless P=NP).
• The PSPACE-complete problems are widely suspected to be outside the more famous complexity classes P (polynomial time) and NP (non-deterministic polynomial time), but that is not known.
• In other words, a problem X is NP-easy if and only if there exists some problem Y in NP such that X is polynomial-time Turing reducible to Y.
• Notice that although it is unknown whether NP is equal to P, we do know that EXPTIME-complete problems are not in P; it has been proven that these problems cannot be solved in polynomial time, by the time hierarchy theorem.
• The New Party (NP; ; Hakka: Sîn Tóng), formerly the Chinese New Party (CNP), is a Chinese nationalist political party in the Republic of China (Taiwan).
• The Edinburgh urban area covers most of the Neighbourhood Partnership areas, however, some of the areas are only covered partly, in particular Almond NP and Pentlands NP.
• The most obvious to visitors include the red kangaroo, western grey kangaroo, Other terrestrial mammals found at Sturt NP also include the dingo, stripe-faced dunnart, paucident planigale, narrow-nosed planigale, dusky hopping mouse and desert mouse.
• Hammond, with partners Richard Eddy and Edward Bonner, founders of the Montana Improvement Company (MIC), enticed the nearly complete Northern Pacific Railroad (NP) to pass through Missoula.
• For instance, a problem is NP-complete if it belongs to NP and all problems in NP have polynomial-time many-one reductions to it.
• For example, in the sentence The old woman eats the falafel, the c-structure analysis is that this is a sentence which is made up of two pieces, a noun phrase (NP) and a verb phrase (VP).
• This disease, along with necrotizing periodontitis (NP) and necrotizing stomatitis, is classified as a necrotizing periodontal disease, one of the three general types of gum disease caused by inflammation of the gums (periodontitis).
• In 1948 the National Party (NP) was voted into power by South Africa's white electorate, and apartheid (Afrikaans for "separateness") policies started to become law.
• Head-driven Phrase Structure Grammar, and most dependency grammars such as Meaning-Text Theory, Functional Generative Description, and Lexicase Grammar also assume the traditional NP analysis of noun phrases, Word Grammar being the one exception.
• This shows another qualitative difference between time and space complexity classes, as nondeterministic time complexity classes are not believed to be closed under complementation; for instance, it is conjectured that NP ≠ co-NP.
• Many-one reductions are valuable because most well-studied complexity classes are closed under some type of many-one reducibility, including P, NP, L, NL, co-NP, PSPACE, EXP, and many others.
• Their existence would prove that the complexity classes P and NP are not equal, thus resolving the foremost unsolved question of theoretical computer science.
