The Persian mathematician al Khowarizmi is credited for having invented the algorithm in 825 AD, as a problem solving method. The word algorithm derives from 'al Khowarizmi.'
Algorithm - Wikipedia, the free encyclopedia:
The word algorithm comes from the name of the 9th century Persian mathematician Abu Abdullah Muhammad ibn Musa al-Khwarizmi. The word algorism originally referred only to the rules of performing arithmetic using Hindu-Arabic numerals but evolved via European Latin translation of al-Khwarizmi's name into algorithm by the 18th century. The word evolved to include all definite procedures for solving problems or performing tasks.
