A tree-like structure or arrangement, often used in computing to describe a hierarchy or branching system. The file system of the computer is organized in an arborescence, making it easy to navigate through folders and subfolders.
The state or condition of being tree-like in appearance or structure. The arborescence of the coral reef was evident in its complex, branching formations.
In graph theory, a directed rooted tree in which all edges are oriented outward from the root; a branching. The algorithm computes the minimum-cost arborescence spanning all vertices.
