Algorithm

An algorithm is a clearly defined, finite sequence of instructions for solving a problem or performing a task. It processes input according to fixed rules and produces a reproducible result.

Functionality and Use

An algorithm operates step-by-step, following clearly defined, executable instructions. It begins with input, processes it in a structured manner, and ends with a result after a finite number of steps. Its behavior is deterministic: Identical inputs under identical conditions always produce the same result.

Algorithms are used in virtually all areas of IT, such as in software applications, search engines, data processing, and automation solutions. They are used to systematically solve problems and automate processes. Depending on their application, they range from simple calculation rules to complex decision-making models.

Examples

• Search algorithms find information in databases or on the internet
• Sorting algorithms organize data, such as lists or search results
• Navigation algorithms calculate optimal routes for map apps
• Cooking recipes describe step-by-step how to prepare dishes
