int GetNodeTriads(Graph, NId, ClosedTriads, OpenTriads)

Note

This function is not yet supported.

Returns the number of Open and Closed triads that a node NId participates in. Note that this function is currently overloaded in the C++ SNAP definition: there are other GetNodeTriads functions which take other arguments. In addition, this function calls either GetNodeTriads_PNGraph, GetNodeTriads_PUNGraph, or GetNodeTriads_PNEANet (depending on the type of Graph), and none of these functions are defined (see below for error report).

Considers the Graph as undirected.

Parameters:

  • Graph: PGraph (input)

    A Snap.py PGraph (considered as undirected)

  • NId: int (input)

    The Id of the node of interest in Graph

  • ClosedTriads: int (input)

    Number of closed triads

  • OpenTriads: int (input)

    Number of open triads

Return value:

  • int (output)

    Returns number of closed triads, and sets OpenTriads and ClosedTriads to the number of open and closed triads that NId participates in in Graph

The following example shows how to compute the number of Open and Closed triads that a node NId participates in for the TNGraph, TUNGraph, and TNEANet classes:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 10, 10)
closed = snap.TInt()
open = snap.TInt()
print snap.GetNodeTriads(Graph, 2, closed, open)

Graph = snap.GenRndGnm(snap.PUNGraph, 10, 10)
closed = snap.TInt()
open = snap.TInt()
print snap.GetNodeTriads(Graph, 2, closed, open)

Graph = snap.GenRndGnm(snap.PNEANet, 10, 10)
closed = snap.TInt()
open = snap.TInt()
print snap.GetNodeTriads(Graph, 2, closed, open)
