The National Institute of Standards and Technology (NIST) — known between 1901 and 1988 as the National Bureau of Standards (NBS) — is a measurement standards laboratory and a non-regulatory agency of the United States Department of Commerce. The institute's official mission is to promote U.S. ...
The complexity class of decision problems for which answers can be checked by an algorithm whose run time is polynomial in the size of the input. Note that this doesn't require or imply that an answer can be found quickly, only that any claimed solution can be verified quickly. "NP" is the class that a Nondeterministic Turing machine accepts in Polynomial time.

Industry:Computer science
The complexity class of decision problems for which answers can be checked for correctness, given a certificate, by an algorithm whose run time is polynomial in the size of the input (that is, it is NP) and no other NP problem is more than a polynomial factor harder. Informally, a problem is NP-complete if answers can be verified quickly, and a quick algorithm to solve this problem can be used to solve all other NP problems quickly.
Industry:Computer science
The complexity class of decision problems that are intrinsically harder than those that can be solved by a nondeterministic Turing machine in polynomial time. When a decision version of a combinatorial optimization problem is proved to belong to the class of NP-complete problems, then the optimization version is NP-hard.
Industry:Computer science
The complexity class of decision problems which are still NP-hard even when all numbers in the input are bounded by some polynomial in the length of the input.
Industry:Computer science
The complexity class of languages that can be accepted by a deterministic Turing machine in polynomial time.
Industry:Computer science
The condition of a finite state machine or Turing machine at a certain time. Informally, the content of memory.
Industry:Computer science
The counterpart in formal logic of a data structure or class instance in the object-oriented sense. Examples are strings, directed graphs, and undirected graphs. Sets of relational structures generalize the notion of languages as sets of strings.
Industry:Computer science
The deepest node in a tree that is an ancestor of two given leaves.
Industry:Computer science
The detection of local similarities among two or more strings.
