Algorithm is a sequence of instructions designed to perform specific actions.
The algorithm, written in the machine language, with the help of computer facilities, is used to provide solutions to problems. In math and computer science, this is a clear specification of how to solve a class of tasks. This can perform data processing, calculations, and automated reasoning duties.
Here are some examples:
Search engines - these use special algorithms to collect the information in the internet and display to the user relevant results for a specific query from their search index.
In programming, algorithms are commonly written as functions, which perform as small programs that can be used by a larger entity. For example, an image displaying application may include a library of special functions, each using a custom algorithm to render different file formats. The image editing program can contain algorithms designed to process and edit image data. Examples of such, include resizing, sharpening, cropping, blurring, color enhancement, and red-eye reduction.
There are many ways to perform an operation in a software program. Developers often try to create the most efficient algorithm, by which programmers can ensure that their programs run fast and use minimal system resources.
Of course not all algorithms are perfect for the first time. As a result, programmers improve existing algorithms and incorporate them into future software updates. When you see a new version of an "optimized" or "faster performance" software program, it means the new version includes more polished algorithms.
Different definitions of an algorithm contain the following series of general requirements:
