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. ...
A compression algorithm that codes strings of characters with codes of a fixed number of bits. Every new string in the input is added to a table until it is full. The codes of existing strings are output instead of the strings.
Industry:Computer science
A computation which takes some inputs and yields an output. Any particular input may yield different outputs at different times. Formally, a mapping from each element in the domain to one or more elements in the range.
Industry:Computer science
A computational problem in which the object is to find the best of all possible solutions. More formally, find a solution in the feasible region which has the minimum (or maximum) value of the objective function.
Industry:Computer science
A computational problem that can be solved by a Turing machine. The problem may have a nonbinary output.
Industry:Computer science
A computational problem that cannot be solved by a Turing machine. The associated function is called an uncomputable function.
Industry:Computer science
A conceptual algorithm with more than one allowed step at certain times and which always takes the right or best step. It is not random, as in randomized algorithm, or indeterminate. Rather it has the supercomputational characteristic of choosing the optimal behavior.
Industry:Computer science
A conceptual idea which generalizes B-trees to multiple dimensions. BV-trees are not balanced, and searching may require backtracking.
Industry:Computer science
A conceptual method of open addressing for a hash table. A collision is resolved by putting the item in the next empty place given by a probe sequence which is independent of sequences for all other key.
