algorithm \AL-guh-RITH-uhm\ , noun:
A step-by-step procedure for solving a problem in a finite number of steps that often involves repetition of an operation.
The notion of an algorithm is basic to all of computer programming, so we should begin with a careful analysis of this concept.

Many algorithms use a strategy called divide and conquer to make problems tractable.

Algorithm is an alteration of algorism, possibly influenced by arithmetic. It comes to us from the Arabic name of a ninth century Persian mathematician and textbook author, via Old French and Medieval Latin: Muhammad ibn-Musa al-Khwarizmi was from the Khwarizm region, an area south of the Aral Sea. Al-Khwarizmi wrote a book titled Kitab al jabr wa'l-muqabala ("Rules of restoring and equating") which is the source of the word algebra.
