Type Parameters:

U - type of the users

All Implemented Interfaces:

GlobalReranker<U,U>

public class WeaknessReranker<U>
extends AbstractNeighborOverlapReranker<U>

Swap reranker for maximizing the average weakness of the graph, i.e. for minimizing the average embeddedness of the network.

WeaknessReranker

public WeaknessReranker(double lambda, int cutOff, java.util.function.Supplier<Normalizer<U>> norm, Graph<U> graph)

Constructor

Parameters:

cutOff - maximum number of edges to consider
