edgeConnectivity {RBGL}R Documentation

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”

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.

Value

A list the first element is the connectivity which is the number of edges that must be cut to separate the graph. The second element is a list of pairs of nodes defining the edges of the minimum disconnecting set
