Algorithm concept - Definition

Algorithm is a word of Arabic origin.It comes from Al Juarismi, the name of a man of Muslim Persian science, possibly born in Baghdad in 780.His name in combination with the Greek word "arithm" with the meaning of "Number," produced "algorithmus" in medieval Latin.

An algorithm is called a series of systematized, successive, finite and rigid rules that lead to the resolution of a problem or the performance of an activity, following them in a prescriptive way.This implies that whenever these instructions are followed, the same result with identical effectiveness.

Although they are used to solve everyday problems, they are especially useful and useful in Informatics, Mathematics and Logic.

To avoid the vagueness and ambiguity that words usually have, in Informatica, it is preferred to use flowcharts in algorithms, rather than flowcharts (describe algorithms graphically) or pseudocodes (need less space than diagrams flow) to describe the steps, which are then implemented in a specific programming language, which encodes the algorithm in a written code, to solve the problems originally raised; in an automated way.The algorithm would be needed after the problem is presented, its description, the identification of the data and information needed to solve it.That is when the algorithm provides the sequence of steps that lead to the resolution.

Euclid's algorithm, described by this mathematician of Greek antiquity in his work "Elements", serves to find two numbers, the greatest common divisor.
