Jump to Informal definition - In mathematics and computer science, an algorithm (/ˈælɡərɪðəm/ (listen)) is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks.‎Formalization · ‎Design · ‎Computer algorithms · ‎Examples. You use code to tell a computer what to do. Before you write code you need an algorithm. An algorithm is a list of steps to follow in order to solve a problem. Algorithm Definition - An algorithm is a step by step method of solving a problem. An algorithm is also used to manipulate data in various ways, such as.

An algorithm is a well-defined procedure that allows a computer to solve define algorithm problem. Another way to describe an algorithm is a sequence of unambiguous instructions. The use of the term 'unambiguous' indicates that there is no room for subjective interpretation.


Every time you ask your computer to carry out the same algorithm, it will do it in exactly the same manner with the exact same result. Consider the define algorithm examples again. Spell checking uses algorithms.

Financial calculations use algorithms. A search engine uses algorithms. In fact, it is difficult to think of a task performed by your computer that does define algorithm use algorithms.

Those errors can be silly, as when Wolfram Alpha mistakes a cute baby goat for a dogbut they can also be downright ugly, as when Google Photos misidentified two black people as gorillas. No one consciously taught the system to form racist conclusions, but the parameters that the programmers set up define algorithm have primed it to arrive there.

Relying on machine learning is risky because these define algorithm systems that learn to get things right by repeatedly getting them define algorithm. Working with them therefore entails accepting almost inevitable errors and screw-ups.

Algorithms determine who should receive government benefits, contribute to predictive policing define algorithm, help anticipate health crisesreschedule airline flights, and much more. So are humans and algorithms mutually exclusive then?


Consider that for many of us, the most familiar example of a machine-learning algorithm is probably the Facebook news feed. In this sense, define algorithm can do plenty of good: Give the driver my address. Meet me outside baggage claim.

Take the shuttle to the rental car place. Follow the directions to get to my house.

Outside baggage claim, catch bus number An image editing program may contain algorithms define algorithm to process image data. Examples of image processing algorithms include cropping, resizing, sharpening, blurring, red-eye reduction, and color enhancement.

What is a computer algorithm?

Proof define algorithm program correctness by use of mathematical induction: Knuth demonstrates the application of mathematical induction to an "extended" version of Euclid's algorithm, and define algorithm proposes "a general method applicable to proving the validity of any algorithm".

With only six core instructions, "Elegant" is the clear winner, compared to "Inelegant" at thirteen instructions. Algorithm analysis [58] indicates why this is the case: Can the algorithms be improved?: Once the programmer judges a program "fit" and "effective"—that is, it computes the function intended define algorithm its author—then the question becomes, can it be improved?

The compactness of "Inelegant" can be improved by the elimination of five steps. But Chaitin proved that compacting an algorithm cannot be automated by a generalized algorithm; [59] rather, it can only be done heuristically ; i.

Observe that steps 4, 5 and 6 are repeated in steps 11, 12 and
