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. ...
Of a node, the distance from the node to the root of the tree. Formal Definition: The depth of the root is 0. The depth of a node is one plus the depth of its parent.
Industry:Computer science
Of a node: the tree node conceptually above or closer to the root than the node and which has a link to the node.
Industry:Computer science
On a string, the operation of deletion, insertion, or substitution performed on a single symbol. On a tree, the deletion of a node v followed by the reassignment of all children of v to the node of which v was formerly a child, the insertion of a new node followed by the reassignment of some arcs departing from the parent of the new node, or the substitution of the label of one of the nodes with another label. Each edit operation may have an associated nonnegative real number representing its cost.

On a wide variety of statistical data, the first digit is d with the probability log<sub>10</sub> ( 1 + 1/d ).
Industry:Computer science
One kind of computation can be simulated by another kind within stated complexity bounds. Most known containment or equality relationships between complexity classes were proved this way.
Industry:Computer science
One of the classes defined by logarithmic, polynomial, and exponential bounds on time and space, for deterministic and nondeterministic machines. These classify most of the important computational problems.
Industry:Computer science
One whose associated language is a recursively enumerable language. Equivalently, there exists an algorithm that halts and outputs 1 for every instance having a "yes" answer, but for instances having a "no" answer is allowed either not to halt or to halt and output 0.
Industry:Computer science
Pack a set of rectangles into a strip of width 1 to minimize the height used. Rectangles may not overlap or be rotated. Without loss of generality, the height of rectangles is at most 1. This is NP-hard.
Industry:Computer science
Partition ("factor") the pattern, x, into left, x<sub>l</sub>, and right, x<sub>r</sub>, parts in such a way to optimize searching. Compare x<sub>r</sub> left to right then, if it matches, compare x<sub>l</sub> right to left.
Industry:Computer science
Partition the vertices while keeping the cost of spanning edges low.
