IRPact_modellierung.network.ErdosRenyiCommunicationGraph

public class ErdosRenyiCommunicationGraph
extends CommunicationGraph

The ErdosRenyiCommunicationGraph is a graph whose edges are all communicative edges and whose topology is initialized after the Erdös-Rényi random model, i.e. a random graph for a fixed number of edges. The number of edges is given by the paramter 'k'

Method Detail

addNodes

public void addNodes(SNConfiguration sNconfiguration,
                     java.util.Set<SNNode> nodesToAdd)
              throws java.lang.IllegalArgumentException

Description copied from class: SocialGraph

(Network type specific) method to add a number of nodes (and the edges that go with them) to the social graph

Overrides:

addNodes in class SocialGraph

Parameters:

sNconfiguration - The configuration the social graph is based on

nodesToAdd - The nodes to be added to the social graph

Throws:

java.lang.IllegalArgumentException

createEdges

protected java.util.Set<SNEdge> createEdges(SNConfiguration sNConfiguration,
                                            java.util.Set<SNNode> initialNodes)
                                     throws java.lang.IllegalArgumentException

Description copied from class: SocialGraph

(Network type specific) method to generate edges between a set of initial nodes. Specifies how edges are (initially) created. Generated edges need to be included in the neighbourhood relations (method only derives WHICH edges to create).

Specified by:

createEdges in class SocialGraph

Parameters:

sNConfiguration - The configuration of the social graph of interest

initialNodes - The nodes the social graph should be initialized with

Returns:

A set of edges of the social graph it is initialized with

Throws:

java.lang.IllegalArgumentException - Will be thrown when the configuration is errornous

getK

public int getK()
