Company Profile:
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 space decomposition method that partitions the underlying space by recursively halving it across the various dimensions instead of permitting the partitioning lines to vary.
Industry:Computer science
A spatial access method where successive levels are split along different dimensions into nonoverlapping cells. Objects are indexed in all cells they intersect.
Industry:Computer science
A spatial access method where successive levels are split by arbitrary hyperplanes. Concave objects are decomposed into convex pieces. Each convex piece is indexed in every cell which it overlaps.
Industry:Computer science
A spatial access method which divides space into a hierarchically of nested boxes. Objects are indexed in the lowest cell which completely contains them.
Industry:Computer science
A spatial access method which is two or more simultaneous grid files. Objects reside in the first grid file where it doesn't have to be split across hyperplanes.
Industry:Computer science
A special character indicating the end of a string.
Industry:Computer science
A special form of recursion where the last operation of a function is a recursive call. The recursion may be optimized away by executing the call in the current stack frame and returning its result rather than creating a new stack frame.
Industry:Computer science
A special form of tail recursion, where the results are produced during the recursive calls and nothing is returned. The recursion may be optimized away by executing the call in the current stack frame, rather than creating a new stack frame, or by deallocating the entire recursion stack at once rather than a little at each return.
Industry:Computer science
A special symbol which matches any other symbol of a given alphabet.
Industry:Computer science
A specialized Patricia tree whose internal nodes store only an integer, k, which is the length of the common prefix of the strings in the children. Equivalently, the strings first differ in the (k+1)<sup>st</sup> character.
