GetNodeTriads(Graph, NId, GroupSet, InGroupEdges, InOutGroupEdges, OutGroupEdges)

Note

This function is not yet supported.

Returns the number of triads between a node NId and a subset of its neighbors GroupSet

Parameters:

• Graph: graph (input)

  A Snap.py graph or a network

• NId: int (input)

  Id of the node

• GroupSet: set (input)

  A subset of its neighbors of node NId

• InGroupEdges: int (output)

  Number of triads (NId, G1, G2), where G1 and G2 are in GroupSet

• InOutGroupEdges: int (output)

  Number of triads (NId, G1, O1), where G1 in GroupSet and O1 not in GroupSet

• OutGroupEdges: int (output)

  Number of triads (NId, O1, O2), where O1 and O2 are not in GroupSet

Return value:

• None

Unexpected behaviors:

• The data structure for GroupSet (TIntSet) is not implemented
• GetNodeTriads method calls three sub-methods (GetNodeTriads_PUNGraph, GetNodeTriads_PNGraph and GetNodeTriads_PNEANet). None of these three are actually implemented, causing errors like “NameError: global name ‘GetNodeTriads_PNGraph’ is not defined”

The following example shows how to calculate the number of triads between a node NId and a subset of its neighbors GroupSet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
NId = Graph.Nodes().next().GetId()
GroupSet = snap.TIntSet()

inGroupEdges = snap.TInt()
inOutGroupEdges = snap.TInt()
outGroupEdges = snap.TInt()

snap.GetNodeTriads(Graph, NId, GroupSet, inGroupEdges, inOutGroupEdges, outGroupEdges)
