Definition 1:

“An algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conducting a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.” Source =


Historical background


“ Etymologically, the word ‘algorithm’ is a combination of the Latin word algorismus, named after Al-Khwarizmi, a 9th-century Persian mathematician, and the Greek word arithmos, i.e. αριθμός, meaning “number”. In English, it was first used in about 1230 and then by Chaucer in 1391. English adopted the French term, but it wasn’t until the late 19th century that “algorithm” took on the meaning that it has in modern English.

Another early use of the word is from 1240, in a manual titled Carmen de Algorismo composed by Alexandre de Villedieu. It begins thus:

Haec algorismus ars praesens dicitur, in qua / Talibus Indorum fruimur bis quinque figuris.

which translates as:

Algorism is the art by which at present we use those Indian figures, which number two times five.

The poem is a few hundred lines long and summarizes the art of calculating with the new style of Indian dice, or Talibus Indorum, or Hindu numerals.” Source = “”


What I think Algorithm is?

When facing to a problem think of that problem as a large harvest, hence you can’t move entire harvest at once. You can only move by doing it by sequence and splits. So Algorithm in my Idea is to take a problem and split in small parts and start solving it part by part.

This is how I solve problems.

In plan section I do follow Algorithm.
