edge

(definition)

Definition: A connection between two vertices of a graph. In a weighted graph, each edge has an number, called a "weight." In a directed graph, an edge goes from one vertex, the source, to another, the target, and hence makes connection in only one direction.

Also known as arc.

directed graph, undirected graph, weighted graph.

See also hyperedge, in-degree, out-degree.

Note: That is, in a directed graph, an edge goes from the source to the target.
