Principle of algorithms – wissenschaft.de

The term algorithm actually comes from mathematics and describes the solution to a problem using strictly defined rules. The best known algorithms in mathematics are the Gaussian elimination method and the Euclidean algorithm. Currently, the algorithm usually determines the input-output relationship.

What is behind the Euclid and Gauss algorithms?

The Euclidean algorithm is a formula that allows you to calculate the greatest common divisor. First, the larger number is divided by the smaller one, and in the second step, the divisor is divided by the remainder. Thus, the question of the greatest common divisor of two numbers can be answered relatively quickly. On the other hand, the Gaussian elimination method is used elsewhere, namely when solving linear equations. The Gauss method is outlined in the form of a matrix after which individual lines are transformed. They are solved using the recursive method.

How does the logic of the algorithm relate to the Internet?

The search engine algorithm also works on the principle of a scheme. First, words are analyzed, followed by comparison of the search term, ranking of the search terms, verification of the results, and context of the query. This is purely technically and within seconds, as the time between entering a search term and displaying a search result is difficult to measure. For any individual website operator who also wants to be actively searched for by users, this means that Google or another search engine is being pulled by “relevant” content offers to appear as a result in the list.

These days, mathematicians are rarely actively involved in delivering the best search results, but rather marketing experts who work for, for example, web agencies and who not only understand the algorithm. They also know which adjustment screws to use in order for your website to appear at the top of the search results. Today seasoned internet agencies have mastered the entire keyboard of search engine optimization. They act as a link building agency and also take care of full optimization on and / or off the page.

How do on-page and off-page metering work?

In both cases, it is important to know the algorithm and provide it with content that it can recognize and return as a response.

  • The most important optimization activities on the website include search engine optimized texts, correctly formed and arranged HTML codes, a URL with meaningful keywords, internal links and deep links. Mobile optimization and short loading times are also points that the algorithm pays attention to when optimizing on the website.
  • In contrast, off-page optimization measures can only be influenced slightly, but they are also a detail that plays a role in the search engine’s algorithm. In practice, this means that when a site is featured, it usually happens through a backlink. For example, one side is “connected” to the other. The algorithm classifies this link, the so-called backlink, as a recommendation that speaks for the content and page.

To what extent is there science behind the search engine algorithm?

A professional online marketing agency first checks the status quo, which is all links leading to the page, or creates a link profile to the page being edited. In practice, this is then compared to the competitor’s link profile. In addition, you can find out to what extent the links lead to your page, which can even be counter-productive and is classified as negative by the algorithm. The result would then be a “penalty” from the search engine, i.e. a worse position in the ranking.

Do algorithms only exist in mathematics and search engines?

The functional area of ​​algorithms is by no means limited to the areas of mathematics and internet marketing. However, these are the most famous areas where algorithms are used. In practice, they are most often used where IT can help find a way out of the maze in order to properly plan and control complex problems.

Algorithms are used in airplanes, but also in ATMs and various devices with Internet access, such as tablets, smartphones and smart TVs. Algorithms are common in e-commerce, streaming, and games. They are also an important base in the financial sector. While they are used in finance, for example to calculate creditworthiness, in games they should provide a fair chance of winning. Even drivers of modern cars are surrounded by algorithms such as an assistant that parks the car on its own or a navigation device that navigates reliably to the right destination. Meteorologists use algorithms to predict weather phenomena. In medicine, algorithms are often used in early warning systems. In nature, an algorithm can predict the risk of a threat.
