What is an algorithm used for?#
Algorithms allow processes to be automated by providing a precise, repeatable recipe for the computer to follow. This eliminates human error, and allows the business to operate efficiently at a scale that would be impossible with manual effort.
How does an algorithm work?#
At its core, an algorithm takes an input, processes it through a series of defined steps, and produces an output. For example, an algorithm for a delivery service might take a list of addresses (input), follow steps to calculate the shortest path connecting all of them (process), and provide an optimized route for the driver (output).
In Artificial Intelligence, algorithms are often more complex. A "learning algorithm" can analyse vast amounts of historical data—such as past customer purchases—to build a predictive model. This model can then be used by another algorithm to generate personalized product recommendations for new customers.
How is an algorithm different from AI?#
An algorithm is a precise set of instructions for accomplishing a task. This differs from the broader concept of 'Artificial Intelligence' (AI). Think of AI as the overall goal of building an intelligent machine, while algorithms are the specific tools and recipes you use to build different parts of that machine's intelligence. A single AI system, like a chatbot, will use many different algorithms to function.
