Algorithm

An algorithm is a self-contained series of instructions to perform a function.

In other words, an algorithm is a means of describing a way to solve a problem so that it can be solved repeatedly, by humans or machines. Computer scientists compare the efficiency of algorithms through the concept of “Algorithmic Complexity” or “Big O” notation.

A cooking recipe is an algorithm for humans. A sorting algorithm is often used in computer programming to explain to a machine how to sort data.

Common algorithms are Pathfinding algorithms such as the optimization Traveling Salesman Problem, Tree Traversal algorithms, and so on.
