[OE. algorism, algrim, augrim, OF. algorisme, F. algorithme (cf.

The spelling with th is due to a supposed connection with Gr. ? number.] 1. The art of calculating by nine figures and zero; computation with Arabic figures.

The art of calculating with any species of notation; as, the algorithms of fractions, proportions, surds, etc. [1913 Webster] algorithm \algorithm\ n. a precise rule (or set of rules) specifying how to solve some problem; a set of procedures guaranteed to find the solution to a problem.

Named after the Iranian, Islamic mathematician, astronomer, astrologer and geographer, {Muhammad ibn Musa al-Khwarizmi}. Technically, an algorithm must reach a result after a {finite} number of steps, thus ruling out {brute force} search methods for certain problems, though some might claim that brute force search was also a valid (generic) algorithm. The term is also used loosely for any sequence of actions (which may or may not terminate). {Paul E. Black's Dictionary of Algorithms, Data Structures, and Problems (http://nist.gov/dads/)}.
