How many types of algorithms are there and what are they?

THE algorithms They are ideal for solving a problem step by step and optimizing the working times of the user and/or the company that uses them. Although they are more associated with computing and information technology, the truth is this They can be used in mathematics and logic, as well as in instruction manuals, among many other variations.

Today, algorithms are linked to digital automation. This tool allows you to control the social networks and Internet search engines, as well as other software for computers or mobile phones.

“In computer science, however, algorithms constitute the backbone of the processes which will then be codified and programmed to be executed by the computer. For this reason, the same the algorithm can be translated to different programming languages, given that it is a set of logical instructions, prior to programming itself,” explains the Concepto portal on the topic.

“Indeed, a computer program can be thought of as a complex set of algorithms ordered and codified using a programming language, for subsequent execution in a computer system,” he adds.

In this sense, all algorithms have a fixed structure composed of three different parts: Entrance (these are the initial instructions and the fundamental data needed by the algorithm are inserted); Process or instructions (composed of the logical operations that the algorithm will undertake with what it receives from the input); Output or output (the results obtained once the process is finished).

The algorithms are sequential, that is, they must be processed one at a time, starting from the first instructions to progressively advance in the process. They are also extremely precise and specific, since the instructions with which it is composed must be specific, direct and easy to follow. Furthermore, the steps to be followed must be sorted and read in a specific order, since incorrect placement of one algorithm or one element of the algorithm can invalidate the others.

Types of algorithms

The “Concepto” portal has published a list with the different types of algorithms, their main functions and characteristics. In detail, each of them:

Algorithms based on the processes required and the sequences involved:

• Computational algorithms. They are those whose resolution can be done using a calculator or computer.
• Non-computational algorithms. They are those that do not depend on computation and do not require computer processes to solve.
• Qualitative algorithms. They are those whose resolution does not involve numerical calculations, but logical and/or formal sequences.
• Quantitative algorithms. They are the ones who depend on mathematical calculations to find their resolution.

Algorithms according to their purpose:

• Search algorithms. They are those that allow you to locate specific trait elements within a dataset.
• Sorting algorithms. They are those that allow you to organize a set of data according to a specific criterion.
• Predictive algorithms. They are those that allow you to make logical future projections of a problem, that is, to search for probable input options.
• Probabilistic algorithms. They are those that allow you to obtain a random result within an established data set.
• Optimization algorithms. They are those who try to make a certain process more efficient and, to achieve this goal, look for alternatives to the elements of a data set.
