GetSccs

GetSccs(Graph, CnComV)

Returns all strongly connected components in Graph.

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network.

  • CnComV: TCnComV, a vector of connected components (output)

    Vector of all strongly-connected components. Each component consists of a TIntV vector of node ids.

Return value:

  • None

The following example shows how to calculate all strongly-connected components in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
Components = snap.TCnComV()
snap.GetSccs(Graph, Components)
for CnCom in Components:
    print "Size of component: %d" % CnCom.Len()

UGraph = snap.GenRndGnm(snap.PUNGraph, 1000, 50)
Components = snap.TCnComV()
snap.GetSccs(UGraph, Components)
for CnCom in Components:
    print "Size of component: %d" % CnCom.Len()

Network = snap.GenRndGnm(snap.PNEANet, 1000, 300)
Components = snap.TCnComV()
snap.GetSccs(Network, Components)
for CnCom in Components:
    print "Size of component: %d" % CnCom.Len()
