A Letter # Algorithm An **algorithm** is a finite and organised sequence of steps used to solve a defined problem or complete a particular task. Algorithms are widely used in mathematics, computer science and software development, but they can also be applied in areas ranging from everyday activities to healthcare. Search engines, mobile applications, navigation systems and digital platforms operate through different algorithms. These algorithms define the order in which data is processed and the actions that should be performed under specific conditions. Creating an algorithm does not simply mean combining technical instructions. It involves dividing a problem into clear, practical and logical steps. An algorithm can be described independently of a programming language through natural language, pseudocode, flowcharts or mathematical expressions. A programming language converts the designed algorithm into code that a computer can execute. The same algorithm may be implemented in languages such as Python, Java or C++. The algorithm therefore represents the solution method, while the program represents its implementation in a particular language. An effective algorithm should be clear, consistent and capable of reaching a defined result. Each step should be understandable, the required inputs should be identified and the process should produce a specific output. Execution time and memory consumption are also important, particularly in systems processing large datasets. Different algorithms designed to solve the same problem may produce different results in terms of performance and resource usage. Algorithms are not limited to computing and software. Root-finding and sorting algorithms are used in mathematics, genetic algorithms support optimisation problems, and evolutionary algorithms explore complex solution spaces. Algorithmic methods may also support diagnostic systems in healthcare, pattern analysis in social sciences and resource planning in business. The appropriate algorithm should be selected according to the nature of the problem and the expected outcome. **Artificial intelligence algorithms** are used to learn patterns from data, generate predictions, perform classifications and support decision-making. These systems process digital information such as images, audio, text and sensor records through mathematical models. Rather than giving computers human intuition or senses, the objective is to learn relationships from examples and produce results for new inputs. Reliability depends on data quality, model design and the methods used to evaluate performance. Deep learning is a machine learning approach based on multilayer artificial neural networks. It can be applied in image recognition, speech processing, natural language processing and recommendation systems. However, not every artificial intelligence application relies on deep learning, and it is not the most suitable method for every problem. Algorithm performance should be evaluated together with accurate problem definition, suitable data and careful human oversight. ## Discover it in the dictionary ### Customer Journey Map A Customer Journey Map is an analytical tool that visually and systematically shows all the stages in which a customer interacts with a brand,… ### Internal Linking Internal linking refers to links that connect one page of a website to another page under the same domain.
