# VertexOutComponent

VertexOutComponent[g,{v1,v2,}]

gives the vertices in the graph g that have a directed path from at least one of v1, v2, .

VertexOutComponent[g,{v1,v2,},k]

gives the vertices with a directed path from at least one of v1, v2, of at most length k.

VertexOutComponent[g,{v1,v2,},{k}]

gives the vertices at length exactly k.

VertexOutComponent[{vw,},]

uses rules vw to specify the graph g.
