In mathematics, and more specifically in graph theory, a multigraph is a graph which is permitted to have multiple edges (also called parallel edges ), that is, edges that have the same end nodes. Thus two vertices may be connected by more than one edge. There are 2 distinct notions of multiple edges: Edges … 展开
A multigraph G is an ordered pair G := (V, E) with
• V a set of vertices or nodes,
• E a multiset of unordered pairs of vertices, called edges or lines. 展开• This article incorporates public domain material from Paul E. Black. "Multigraph". Dictionary of Algorithms and Data Structures. NIST. 展开
