edgeConnectivity: computed edge connectivity and min disconnecting set for an undirected graph

Description

computed edge connectivity and min disconnecting set for an undirected graph

Usage

edgeConnectivity(g)

Arguments

g

an instance of the graph class with edgemode “undirected”

Value

A list:

connectivity

the integer describing the number of edges that must be severed to obtain two components

minDisconSet

a list (of length connectivity) of pairs of node names describing the edges that need to be cut to obtain two components

Details

Consider a graph G consisting of a single connected component. The edge connectivity of G is the minimum number of edges in G that can be cut to produce a graph with two (disconnected) components. The set of edges in this cut is called the minimum disconnecting set.
