Minimum Vertex Cut


A minimum vertex cut of a graph is a vertex cut of smallest possible size.

A vertex cut set of size 1 in a connected graph corresponds to an articulation vertex.

The size of a minimum vertex cut in a connected graph G gives the vertex connectivity kappa(G).

Complete graphs have no vertex cuts since there is no subset of vertices whose removal disconnected a complete graph.

A single minimum vertex cut of a connected graph G can be found in the Wolfram Language using the function FindVertexCut[G].
