Moody and White provide an algorithm for identifying k-components in a graph, which is based on Kanevsky’s algorithm for finding all minimum-size node cut-sets of a graph (implemented in all_node_cuts() function):

  1. Compute node connectivity, k, of the input graph G.
  2. Identify all k-cutsets at the current level of connectivity using Kanevsky’s algorithm.
  3. Generate new graph components based on the removal of these cutsets. Nodes in a cutset belong to both sides of the induced cut.
  4. If the graph is neither complete nor trivial, return to 1; else end.

In [7]:
# returns all minimum k cutsets of an undirected graph
# i.e., the set(s) of nodes of cardinality equal to the node connectivity of G
# thus if removed, would break G into two or more connected components
cutsets = list(nx.all_node_cuts(Gc))
