Detailed Description

This measure evaluates how fragmented a partition is.

The fragmentation of a single cluster is defined as one minus the number of nodes in its maximum connected componented divided by its total number of nodes. Smaller values thus indicate a smaller fragmentation.

Member Function Documentation

virtual bool NetworKit::PartitionFragmentation::isParallel ( ) const
false - only minor parts of this implementation are parallel.

Reimplemented from NetworKit::Algorithm.

virtual bool NetworKit::PartitionFragmentation::isSmallBetter ( ) const
true - smaller values are better than larger values.

Implements NetworKit::LocalCommunityEvaluation.

void NetworKit::PartitionFragmentation::run ( )

Execute the algorithm.

Implements NetworKit::Algorithm.
