GetNodeEcc

GetNodeEcc(NId, IsDir=False)

A graph method that returns node eccentricity, the largest shortest-path distance from the node NId to any other node.

Parameters:

• NId: int

  A node id.

• (optional) IsDir: bool

  Indicates whether the edges should be considered directed or undirected.

Return value:

• int

  The eccentricity of node NId.

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

import snap

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

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

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