noun

1. Mathematics. a set of rules for solving a problem in a finite number of steps, such as the Euclidean algorithm for finding the greatest common divisor.

2. Computers. an ordered set of instructions recursively applied to transform data input into processed data output, such as a mathematical solution, search engine result, descriptive statistics, or predictive text suggestions.

Usage

What is an algorithm? An algorithm is a set of instructions or rules that can be followed to solve a problem.Algorithms are most commonly used in mathematics and computing, and they can often be very complex or have many steps or sets of instructions.For example, your teacher asks you to add 537 and 162. You might solve the problem by lining up 162 under 537 and adding the columns of numbers together. You add the 7 and 2 in the ones column to get 9, Next, you add the numbers in the tens column (3 and 6) to get 9. Finally, you add 5 and 1 in the hundreds column and get 6. Your answer, then, is 699. You have followed an addition algorithm to find the solution.In computing, a computer coder will create a set of instructions (the algorithm) that a computer or artificial intelligence will use to solve a problem or will consult in order to achieve a goal. Let’s say you spend the day watching Star Wars videos on YouTube. With each video you watch, the website will recommend other videos it thinks you will like. How does it know what you like? It runs an algorithm that finds videos that are similar to the ones you’ve already watched. If Darth Vader shows up in a video of a car commercial, YouTube will likely recommend it to you to watch because Vader was in a lot of the Star Wars videos you’ve already watched.
