GetNodeEcc

GetNodeEcc(Graph, NId, IsDir=False)

Returns node eccentricity, the largest shortest-path distance from the node NId to any other node in the Graph.

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network.

  • NId: int (output)

    A node id in Graph.

  • IsDir: bool (input)

    Indicates whether the edges should be considered directed or undirected.

Return value:

  • int

    The eccentricity of node NId within Graph.

The following example shows how to calculate eccentricity for nodes in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 10, 30)
for NI in Graph.Nodes():
    print NI.GetId(), snap.GetNodeEcc(Graph, NI.GetId(), True)

UGraph = snap.GenRndGnm(snap.PUNGraph, 10, 30)
for NI in UGraph.Nodes():
    print NI.GetId(), snap.GetNodeEcc(UGraph, NI.GetId(), False)

Network = snap.GenRndGnm(snap.PNEANet, 10, 30)
for NI in Network.Nodes():
    print NI.GetId(), snap.GetNodeEcc(Network, NI.GetId(), True)
