GetNodeTriads(Graph, NId, GroupSet)

Note

This function is not yet supported.

Returns the number of closed triads a node NId participates in. OR, if the parameter GroupSet is included, returns the number of triads between NId and a subset of its neighbors (given by GroupSet). Considers Graph to be undirected.

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network

  • NId: int (input)

    NId of the node of interest

  • GroupSet: TIntSet (input) (optional)

    Set of NIds representing a subset of the neighbors of the node of interest

Return value:

  • ClosedTriads: int

    Number of triads the node of interest (NId) participates in

OR

  • InGroupEdges: int

    Number of triads between the node of interest (NId) and a subset of its neighbors (GroupSet)

Note

This function does not currently perform as indicated. It is not yet implemented in SNAP.py. The error message is as follows: “if type(tspec) == PNGraph : return GetNodeTriads_PNGraph(tspec, * args) NameError: global name ‘GetNodeTriads_PNGraph’ is not defined.” The example code below is theoretical and has not been tested.

The following example shows how to calculate the number of triads a node participates in for nodes in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
NId = 1
print GetNodeTriads(Graph, NId)

Graph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
NId = 1
print GetNodeTriads(Graph, NId)

Graph = snap.GenRndGnm(snap.PNEANet, 100, 1000)
NId = 1
print GetNodeTriads(Graph, NId)
