bandwidth: Compute bandwidth for an undirected graph

In RBGL: An interface to the BOOST graph library

Description

Compute bandwidth for an undirected graph

Usage

bandwidth(g)

Arguments

g	an instance of the graph class with edgemode “undirected”

Details

The bandwidth of an undirected graph G=(V, E) is the maximum distance between two adjacent vertices. See documentation on bandwidth in Boost Graph Library for more details.

Value

bandwidth

the bandwidth of the given graph
