In complexity theory, the class NC ( for " Nick's Class ") is the set of decision problems decidable in polylogarithmic time on a parallel computer with a polynomial number of processors.

One major open question in complexity theory is whether or not every containment in the NC hierarchy is proper.

* NC a complexity class named after Nick Pippenger

The complexity class, Nick's Class ( NC ), of problems quickly solvable on a parallel computer, was named by Stephen Cook after Nick Pippenger for his research on circuits with polylogarithmic depth and polynomial size.

In circuit complexity, NL can be placed within the NC hierarchy.

If NC is a complexity class associated with non-deterministic machines then # C =

If we use NC reductions, that is, reductions which can operate in polylogarithmic time on a parallel computer with a polynomial number of processors, then all P-complete problems lie outside NC and so cannot be effectively parallelized, under the unproven assumption that NC ≠ P. If we use the weaker log-space reduction, this remains true, but additionally we learn that all P-complete problems lie outside L under the weaker unproven assumption that L ≠ P. In this latter case the set P-complete may be smaller.

A second important example is the use / mention distinction, as in the following example, where " blue " is clearly not functioning as an adjective ( the Brown Corpus tag set appends the suffix "- NC " in such cases ):

Over the next 30 years the standard was further defined and extended and evolved into a set of standards including National Coarse ( NC ), National Fine ( NF ), and National Pipe Taper ( NPT ).

A frequency analysis is performed for a finite number of representative frequencies and a set of templates are obtained in the NC diagram which encloses the behaviour of the open loop system at each frequency.

With these considerations and the selection of the same set of frequencies used for the templates, the frequency constraints for the behaviour of the system loop are computed and represented on the Nichols Chart ( NC ) as curves.

Bexleyheath closed in 1986, with work moved to Plumstead, Catford, and Sidcup garages, although it re-opened in 1988 under the guise of Bexleybus, a unit set up by London Buses under de-regulation, and had a large and varied allocation from Iveco / Robin Hood's & MCW Metroriders to NC Olympians & Fleetlines.

Equivalently, NC can be defined as those decision problems decidable by a uniform Boolean circuit ( which can be calculated from the length of the input ) with polylogarithmic depth and a polynomial number of gates.

NC < sup > i </ sup > is the class of decision problems decidable by uniform boolean circuits with a polynomial number of gates of at most two inputs and depth O ( log < sup > i </ sup > n ), or the class of decision problems solvable in time O ( log < sup > i </ sup > n ) on a parallel computer with a polynomial number of processors.

One indicator of the personal character of " Gentleman Ned " Jarrett is demonstrated by the decision to sell his 1961 ( raced as # 11 ) Chevrolet to Wendell Scott ( the first NASCAR African American driver ) who travelled from his Virginia home to Ned's shop on West " A " Street in Newton, NC to take delivery of the ' 61 Chevy Bel Air ( raced the previous season ) when Ned changed to Fords in 1962.

Just as the class P can be thought of as the tractable problems ( Cobham's thesis ), so NC can be thought of as the problems that can be efficiently solved on a parallel computer.

It is unknown whether NC = P, but most researchers suspect this to be false, meaning that there are probably some tractable problems which are " inherently sequential " and cannot significantly be sped up by using parallelism.

As with P, by a slight abuse of language, one might classify function problems and search problems as being in NC.

NC is known to include many problems, including

Similarly, we have that NC is equivalent to the problems solvable on an alternating Turing machine restricted to at most two options at each step with space and alternations.

The class P, typically taken to consist of all the " tractable " problems for a sequential computer, contains the class NC, which consists of those problems which can be efficiently solved on a parallel computer.

It is not known whether NC = P. In other words, it is not known whether there are any tractable problems that are inherently sequential.

Similarly to the use of NP-complete problems to analyze the P = NP question, the P-complete problems, viewed as the " probably not parallelizable " or " probably inherently sequential " problems, serves in a similar manner to study the NC = P question.

Finding an efficient way to parallelize the solution to some P-complete problem would show that NC = P. It can also be thought of as the " problems requiring superlogarithmic space "; a log-space solution to a P-complete problem ( using the definition based on log-space reductions ) would imply L = P.

Similarly there are problems that are not known to be either P-complete or NC, but are thought to be difficult to parallelize.

NC is a subset of P because polylogarithmic parallel computations can be simulated by polynomial-time sequential ones.

Although the problem is not known to be in NC, parallel algorithms with time superior to the Euclidean algorithm exist ; the best known deterministic algorithm is by Chor and Goldreich, which ( in the CRCW-PRAM model ) can solve the problem in O ( n / log n ) time with n < sup > 1 + ε </ sup > processors.

In other words, a problem is in NC if there exist constants c and k such that it can be solved in time O ( log < sup > c </ sup > n ) using O ( n < sup > k </ sup >) parallel processors.

This reduced the cost of programming for NC machines and by the mid 1960s, APT runs accounted for a third of all computer time at large aviation firms.

Its long-term coexistence with less networked variants of NC and CNC is explained by the fact that individual firms tend to stick with whatever is profitable, and their time and money for trying out alternatives is limited.
