A brief description.

The terms hierarchical partitions, trees or hierarchical communities, although, different mathematical objects, for practical purposes, here are used as equivalent terms.

The term node should not be confused with the module of a tree. In some sense, a tree is a network, and as such, it has nodes. However, here, the word node is reserved to the elements contained in a hierarchical community structure. To refer to the “nodes” of a tree, it is used instead the term module, or equivalents.
