GetRndSubGraph

GetRndSubGraph(numNodes)

A graph method that randomly selects numNodes nodes from the input graph and returns an induced graph on those nodes.

Parameters:

• numNodes: int

  Number of nodes desired in the output graph.

Return value:

• graph

  The induced sub-graph.

The following example shows how to get a random subgraph of size 10 from a graph of type TNGraph, TUNGraph, or TNEANet:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 1000)
SubGraph = Graph.GetRndSubGraph(10)

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 1000)
SubUGraph = UGraph.GetRndSubGraph(10)

Network = snap.GenRndGnm(snap.TNEANet, 100, 1000)
SubNetwork = Network.GetRndSubGraph(10)
