Syn: Neptunium, atomic number 93. [WordNet 1.5] From WordNet (r) 2.0 [wn]: Np n 1: a radioactive transuranic metallic element; found in trace amounts in uranium ores; a by-product of the production of plutonium [syn: {neptunium}, {atomic number 93}] 2: a registered nurse who has received special training and can perform many of the duties of a physician [syn: {nurse practitioner}, {nurse clinician}] From Virtual Entity of Relevant Acronyms (Version 1.9, June 2002) [vera]: NP Network Performance From Virtual Entity of Relevant Acronyms (Version 1.9, June 2002) [vera]: NP No Problem (telecommunication, Usenet, IRC) From Jargon File (4.3.1, 29 Jun 2001) [jargon]: NP- /N-P/ pref. Extremely. Used to modify adjectives describing a level or quality of difficulty; the connotation is often `more so than it should be'. This is generalized from the computer-science terms `NP-hard' and `NP-complete'; NP-complete problems all seem to be very hard, but so far no one has found a proof that they are. NP is the set of Nondeterministic-Polynomial algorithms, those that can be completed by a nondeterministic Turing machine in an amount of time that is a polynomial function of the size of the input; a solution for one NP-complete problem would solve all the others. "Coding a BitBlt implementation to perform correctly in every case is NP-annoying." Note, however, that strictly speaking this usage is misleading; there are plenty of easy problems in class NP. NP-complete problems are hard not because they are in class NP, but because they are the hardest problems in class NP. From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]: NP{nondeterministic polynomial time}. [{Jargon File}] From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]: np The {country code} for Nepal. (1999-01-27)
