Algorithm Definition

An algorithm is a set of instructions or a formula designed to solve a problem or to perform a specific task. The most common example of an algorithm is an illustration of a mathematical formula. In computer programming, algorithm serves as a blueprint, which assists in the development of software-defined for a specific purpose. Developers aim to formulate efficient algorithms that operate at a fast pace and use minimal system resources. Algorithms generally evolve over a course of time and application developers continually strive towards the improvement of existing algorithms, providing these upgrades to the customers in the form of software updates.

Different Types of algorithms

There are many types of algorithms. The most common types of algorithms are Encryption algorithms, bees algorithm, and cache algorithm. Encryption algorithms protect data by transforming it according to specific instructions. Bees algorithm are used to solve complex problems by the principle of ‘search and prioritize’. Cache algorithm directs redundant data to be discarded to the device’s cache of information.   

Algorithm Explained in Detail

The term ‘Algorithm’ is coined from a mathematician’s name, Mohammed ibn-Musa al- Khwarizmi, a member of a royal court in Baghdad. An algorithm is a method or rule for solving a problem based on conducting a series o specified actions. The theory of algorithm is not new; it has existed for several centuries. The present-day concept of algorithm started with the attempts to crack up a solution for Entscheidungsproblem (decision-making problem) created by David Hilbert in 1928.

Usually, in mathematics and computer science, an algorithm refers to a procedure that solves a periodic problem. An algorithm can also be a computer program. According to mathematics and computer science, an algorithm is an explicit condition of how to solve a set of problems. It can carry out calculations, computerized logical and reasoning tasks, and data processing.

What are algorithms actually used for?

Algorithms are extensively used in every aspect of information technology (IT). For instance, an algorithm for a search engine takes strings of keywords for search and operators as input. The search engine then searches the related database for appropriate web pages and shows the results. An algorithm is a helpful technique for the calculation of a function. It can be expressed in a fixed space and time and in a well-defined language.

Algorithms include the step by step formula designed to execute an operation that leads to the result if followed rightly. They have a distinct start and a distinct end, and a fixed number of steps. They are appropriate for solving structured problems which don't require value judgments.

The concept of algorithms can be applied to anything, for anything that we want the computer to analyze. From concepts of mathematics like "an algorithm can tell if a number is even or not” to AI systems like “an algorithm that, based on the videos you watch on YouTube, determines which videos will be suitable for your choice.”
