... A prescribed set of well-defined rules or instructions for the solution of a problem, such as the performance of a calculation, in a finite number of steps. Expressing an algorithm in a formal notation is one of the main parts of a program ; much that is said about programs applies to algorithms, and vice versa. An effective algorithm is one that is effectively computable ( see effective computability ). The study of whether effective algorithms exist to compute particular quantities forms the basis of the theory of algorithms. Save for the...

...algorithm ( social media algorithm ) An automated set of rules for sorting data. Computerized algorithms are used for a variety of purposes in online and mobile media, such as for text prediction or phrase completion (as when users type search queries or compose text messages). Content filtering algorithms are widespread. In sentiment analysis , algorithms are used to classify posts as reflecting positive, negative, and neutral evaluations of a brand by users.

...algorithm A method of solving a problem, involving a finite series of steps. In computing practice the algorithm denotes the expression on paper of the proposed computing process (often by means of a flowchart) prior to the preparation of the program. If no algorithm is possible a heuristic solution has to be sought. See also Turing machine...

... (derived from the name of the Islamic mathematician Al-Khowarizmi) A set of rules or instructions that will result in the solution of a problem. An algorithm gives a decision procedure, or computable method for solving a problem. Although an algorithm will solve the problem, it may not do so efficiently, and in the theory of computation algorithms may be measured for their efficiency and their behaviour in various circumstances, for example across average cases and unfavourable cases. See also Church’s thesis , decision problem , recursive , ...

... A process or sequential set of rules or instructions necessary for performing a specific task or solving a particular problem. Algorithms are applied to the marketing process, and their use can increase the speed of the process. With the creation of mass, complex data, algorithms can assist in matching customer behaviour with services and products , as many customers demand instant responses from suppliers. For instance, a retailer might use an algorithm to optimize product prices or to recommend the products to promote based on gaps in a...

... . An algorithm is a mechanical procedure for determining the value of a function for any argument from a specified domain . For example, addition is a function which maps pairs of natural numbers on to a natural number (the sum of the pair). The simple paper-and-pencil rules for determining the sum of any two numbers are an algorithm for the addition function. A mechanical procedure for deciding whether a given object has a particular property is also called an algorithm. So, for example, the truth-table test for deciding whether a formula of the...

... . In a general sense, an algorithm is an instruction (or a sequence of instructions) according to which a process has to occur. More specifically, a computer program is an instance or an implementation of an algorithm. This instruction has to be formulated in such a precise way so that it can be performed by an operator that is capable of interpreting and executing the algorithm's instructions. Examples of algorithms are the rules for adding and subtracting two or more numbers, for playing board games, for cooking according to recipes, and so on....
