WeaklyConnectedComponents

WeaklyConnectedComponents[g]
gives the weakly connected components of the graph g.

WeaklyConnectedComponents[g,{v1,v2,}]
gives the weakly connected components that include at least one of the vertices v1, v2, .

WeaklyConnectedComponents[g,patt]
gives the connected components that include a vertex that matches the pattern patt.

WeaklyConnectedComponents[{vw,},]
uses rules vw to specify the graph g.

DetailsDetails

  • WeaklyConnectedComponents returns a list of components {c1,c2,}, where each component ci is given as a list of vertices.
  • Vertices u and v are in the same component ci if there is a sequence of edges joining u and v.
  • Components ci are ordered by their length, with the largest component first.
  • WeaklyConnectedComponents works with undirected graphs, directed graphs, multigraphs, and mixed graphs.
