KEdgeConnectedComponents

KEdgeConnectedComponents[g,k]

gives the k-edge-connected components of the graph g.

KEdgeConnectedComponents[g,k,{v1,v2,…}]

gives the k-edge-connected components that include at least one of the vertices v1, v2, ….

KEdgeConnectedComponents[{vw,…},…]

uses rules vw to specify the graph g.

Details

  • KEdgeConnectedComponents is also known as k-edge components.
  • KEdgeConnectedComponents returns a list of components {c1,c2,…}, where each component ci is given as a list of vertices.
  • The component ci generates a maximal k-edge-connected subgraph of g.
  • For an undirected graph, the vertices u and v are in the same component if there are at least k edge-disjoint paths from u to v.
  • For a directed graph, the vertices u and v are in the same component if there are at least k edge-disjoint directed paths from u to v and from v to u.
