FindVertexCut

FindVertexCut[g]

finds a smallest vertex cut of the graph g.

FindVertexCut[g,s,t]

finds a smallest s-t vertex cut of the graph g.

FindVertexCut[{vw,},]

uses rules vw to specify the graph g.

Details

  • A vertex cut of a graph g is a list of vertices whose deletion from g disconnects g.
  • The s-t vertex cut is a list of vertices whose deletion from g disconnects g, with s and t in two different connected components.
  • For a disconnected graph, FindVertexCut will return an empty list {}.
