Class ErdosRenyiGenerator<V,​E>

  • All Implemented Interfaces:
    GraphGenerator<V,​E>, org.apache.commons.collections4.Factory<edu.uci.ics.jung.graph.Graph<V,​E>>

    public class ErdosRenyiGenerator<V,​E>
    extends java.lang.Object
    implements GraphGenerator<V,​E>
    Generates a random graph using the Erdos-Renyi binomial model (each pair of vertices is connected with probability p).
