networks

 diameter
 compute the diameter of a graph or network

 Calling Sequence diameter(G)

Parameters

 G - graph or network

Description

 • Important: The networks package has been deprecated.  Use the superseding command GraphTheory[Diameter] instead.
 • This routine uses allpairs() to compute the minimum distance between any two vertices.
 • The result is returned as a number indicating the diameter, or infinity if the graph is disconnected.
 • Edge weights are assumed to be lengths or distances. Thus edge weights must be non-negative.
 • Undirected edges are assumed to be bidirectional.
 • This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[diameter](...).
