Usage
edgeConnectivity(g)
Arguments
- g
- an instance of the
graph
class withedgemode
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:
- 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
