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 search tree with the restrictions that all leaves are at the same depth and all internal nodes have between a and b children, where a and b are integers such that 2 ≤ a ≤ (b+1)/2. The root may have as few as 2 children.
Industry:Computer science
A searching problem for which one can decompose the searched domain into subsets, find answers from these subsets, and combine these answers to form the solution to the original problem. More formally a problem with a query Q is decomposable given if there exists an efficiently computable associative and commutative binary operator @ satisfying the condition: Q(x, A ∪ B) = @(Q(x,A),Q(x,B)).
Industry:Computer science
A sequence of circuits, one for each input length n, that can be efficiently generated by a Turing machine.
Industry:Computer science
A sequence of numbers where each number is the sum of the k preceding numbers. The usual Fibonacci numbers occur when k=2. Formal Definition: <ul> <li> F<sup>(k)</sup><sub>n</sub> = F<sup>(k)</sup><sub>n-1</sub> + F<sup>(k)</sup><sub>n-2</sub> + . . . + F<sup>(k)</sup><sub>n-k</sub> for n ≥ k. <li>F<sup>(k)</sup><sub>k-1</sub> = 1 <li>F<sup>(k)</sup><sub>n</sub> = 0 for 0 ≤ n ≤ k-2 </ul>

A series of moves of a chess knight that visits all squares on the board exactly once.
Industry:Computer science
A set of bit vectors such that no vector is a subset of a bitwise or of a small number of others.
Industry:Computer science
A set of data values and associated operations that are precisely specified independent of any particular implementation.
