Definition of algorithm

A clear instruction on how to solve a specific problem is called an algorithm. The algorithm is particularly widespread in mathematics, computer science and linguistic research. Algorithms are instructions for problem-solving strategies.

Algorithm and SEO

In the field of search engine optimization, the algorithm is understood as the core program of search engines such as Goolge, Bing or Yahoo! The search engine algorithm delivers the desired keywords and corresponding results in the search results pages (SERPs). They are arranged in a specific order according to the ranking factors.

Google’s PageRank (PR) is probably one of the best-known algorithms. Search engine algorithms are constantly being adapted, changed and made more complex as new factors are constantly being added.

As an experienced and competent SEO agency, we are happy to help you influence the relevant factors for the benefit of our clients.

What is an algorithm?

An algorithm represents a defined and finite procedure for solving a problem and can be formulated in both human and machine language.

Algorithms can actually be found in every computer program, a kind of instruction manual that specifies a certain task step by step.

Algorithms exist in many different areas. In mathematics, for example, there is the Euclidean algorithm. It describes a clear procedure for determining the greatest common divisor of two natural numbers. But everyday things can also be algorithms.

In simplified terms, this refers to a defined and finite procedure with which a problem is solved. A step-by-step guide to achieving a specific goal. Individual steps are clearly defined so that they are carried out in the intended manner and sequence. An algorithm is not a set of instructions for a problem, but a specific type of problem solver.

An algorithm must be able to be completely described with a finite text (static finiteness) and must not occupy an unlimited amount of memory with intermediate results at runtime (dynamic finiteness) if it is to deliver a result after a finite time.(Finiteness = finiteness)

An algorithm must provide a specific instruction for an intermediate result at all times. A clear procedure therefore means only one subsequent step for each intermediate result, in which case the algorithm is deterministic.(Determinacy/determinism = definiteness, dependency, being fixed)

There are also non-deterministic algorithms. They contain at least one step in which an intermediate result can be further processed in several equivalent ways. Deterministic algorithms therefore always have determined results. Non-deterministic algorithms, on the other hand, deliver results in different ways to determined results.

An algorithm should accept input values and deliver a suitable result. This also means that processing is aborted in the event of invalid intermediate results or inputs and does not enter an endless loop. An algorithm is normally terminating, i.e. it must deliver a result after a finite time.

Algorithms Computer Science

There are countless algorithms that are used in software development:

  • Complex calculations
  • Sorting process
  • Encryption method
  • Search procedure
  • Compression

Algorithms Hardware area

An algorithm can also be implemented in electronic devices using hardware. An application-specific integrated circuit (ASIC), for example, is a circuit that maps a specific algorithm.
