# Algowiki:Levels of classification

## Contents

## 1 Problem level

The article belongs to this level if it describes a problem which, perhaps, can be solved by means of different mathematical methods.

Articles in this classification level are marked with the {{level-p}} template, which adds them to the category Problem level.

## 2 Method level

The article belongs to this level if it describes a mathematical method for solving a problem. For this method the existence of different algorithms that implement it is quite possible.

Articles in this classification level are marked with the {{level-m}} template, which adds them to the category Method level.

## 3 Algorithm level

The article belongs to this level if it describes a specific algorithm that implements the solution of a certain problem by some method.

Articles in this classification level are marked with the {{level-a}} template, which adds them to the category Algorithm level. Articles in which the template {{algorithm}} is present are marked automatically.

## 4 Level of classification next to the internal link

In order to display the level of classification next to the internal link to the article the {{level}} template is used. One of the templates {{level-p}}, {{level-m}}, {{level-a}} needs to be present in the article itself at the same time. For example:

```
{{level|Cholesky decomposition}}
```
