GetTriads (SWIG)

GetTriads(Graph, NIdCOTriadV, SampleNodes=- 1)

Computes the number of closed and open triads for every node in Graph. Considers the graph as undirected.

Parameters:

• Graph: graph (input)

  A Snap.py graph or a network

• NIdCOTriadV: TIntTrV, a vector of triplets (integer, integer, integer) (output)

  A triple contains (node id, number of closed triads, number of open triads). Closed triads are pairs of node’s neighbors that are connected between themselves. Open triads are pairs of node’s neighbors that are not connected.

• SampleNodes: integer (input)

  If !=-1 then compute triads only for a random sample of SampleNodes nodes. Useful for approximate but quick computations.

Return value:

• None

The following example shows how to compute the number of closed and open triads for nodes in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
TriadV = snap.TIntTrV()
snap.GetTriads(Graph, TriadV)
for triple in TriadV:
    print(triple.Val1(), triple.Val2(), triple.Val3())

Graph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
TriadV = snap.TIntTrV()
snap.GetTriads(Graph, TriadV)
for triple in TriadV:
    print(triple.Val1(), triple.Val2(), triple.Val3())

Graph = snap.GenRndGnm(snap.PNEANet, 100, 1000)
TriadV = snap.TIntTrV()
snap.GetTriads(Graph, TriadV)
for triple in TriadV:
    print(triple.Val1(), triple.Val2(), triple.Val3())
