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 quantum algorithm to determine whether a function is constant or balanced, that is, returns 1 for half the domain and 0 for the other half. For a function taking n input qubits, first, do Hadamards on n 0's, forming all possible inputs, and a single 1, which will be the answer qubit. Next, run the function once; this exclusive or's the result with the answer qubit. Finally, do Hadamards on the n inputs again, and measure the answer qubit. If it is 0, the function is constant, otherwise the function is balanced.
Industry:Computer science
A randomized algorithm that always produces correct results, with the only variation from one run to another being its running time.
Industry:Computer science
A randomized algorithm that may produce incorrect results, but with bounded error probability.
Industry:Computer science
A randomized variant of an ordered linked list with additional, parallel lists. Parallel lists at higher levels skip geometrically more items. Searching begins at the highest level, to quickly get to the right part of the list, then uses progressively lower level lists. A new item is added by randomly selecting a level, then inserting it in order in the lists for that and all lower levels. With enough levels, searching is O(log n).
Industry:Computer science
A rearrangement of elements, where none are lost, added, or changed. The Fisher-Yates shuffle randomly permutes elements.

Industry:Computer science
A rectilinear polygon P in which every horizontal or vertical segment connecting two points in P lies totally within P.
Industry:Computer science
A recursive algorithm, especially a sort algorithm, where dividing (splitting) into smaller problems is quick or simple and combining (merging) the solutions is time consuming or complex.
