                                     scala.reflect.ClassTag<ED> evidence$2)

Compute the strongly connected component (SCC) of each vertex and return a graph with the vertex value containing the lowest vertex id in the SCC containing that vertex.

Parameters:

graph - the graph for which to compute the SCC

numIter - (undocumented)

evidence$1 - (undocumented)

evidence$2 - (undocumented)

Returns:

a graph with vertex attributes containing the smallest vertex id in each SCC
