GetNodeEcc (SWIG)

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))
