GetWccs

GetWccs(Graph, CnComV)

Returns all weakly 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 weakly-connected components. Each component consists of a TIntV vector of node ids.

Return value:

• None

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

import snap

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

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

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