class PartitionHubDominance : public NetworKit::LocalPartitionEvaluation¶

A quality measure that measures the dominance of hubs in clusters. The hub dominance of a single cluster is defined as the maximum cluster-internal degree of a node in that cluster divided by the maximum cluster-internal degree, i.e. the number of nodes in the cluster minus one. The value for all clusters is defined as the average of all clusters. Strictly speaking this is not a quality measure as this is rather dependent on the type of the considered graph, for more information see Lancichinetti A, Kivel M, Saramki J, Fortunato S (2010) Characterizing the Community Structure of Complex Networks PLoS ONE 5(8): e11976. doi: 10.1371/journal.pone.0011976 http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0011976

Public Functions

virtual void run() override¶

Execute the algorithm. The algorithm is not parallel.

inline virtual bool isSmallBetter() const override¶

Returns:

false - small values are not better, large values indicate better cluster cohesion.

LocalPartitionEvaluation(const Graph &G, const Partition &P)¶

Initialize the partition evaluation method.

Parameters:

• G – The graph on which the evaluation shall be performed

• P – The partition that shall be evaluated.
