Algorithm (Dictionary)

Definition

A systematic set of procedures or methods developed and followed to solve any issue step by step, based on a symbolic formula. The initial foundations of the systematic calculation principle were laid by Muhammad Ibn Musa al-Khwarizmi, thus, in the Middle Ages, calculation methods based on the decimal system were referred to by this name. This method, which became the basis of today's arithmetic, has found extensive application and opportunities in computers and has become a term used in computer programs.

Origin

The term "algorithm" has its roots in the name of the famous 9th-century Muslim mathematician Al-Khwarizmi (full name Abu Ja'far Muhammad Ibn Musa al-Khwarizmi). Al-Khwarizmi wrote important works introducing the Hindu-Arabic numeral system and mathematical methods to Europe. One of these works is the algebra book "Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala." During the Middle Ages, his works were translated into Latin, and his name was referred to as "Algoritmi" or "Algorismus." Initially, the term "Algorismus" was used to denote the method of calculation using Hindu-Arabic numerals. Over time, this term came to generally refer to step-by-step calculation methods. It evolved into "algorithm" in English, French, and other European languages and gained the modern meaning we know today, referring to sequences of steps followed to solve specific problems, not just in mathematics but also in computer science and many other fields.
