KVertexConnectedGraphQ

KVertexConnectedGraphQ[g,k]

yields True if the graph g is k-vertex-connected and False otherwise.

Details

  • KVertexConnectedGraphQ is also known as k-connected.
  • A graph is k-vertex-connected if there are at least k vertex-disjoint paths between every pair of vertices.
