void NetworKit::DynBetweenness::run ( )
overridevirtual

Runs static betweenness centrality algorithm on the initial graph.

Run method that stores a single shortest path for each node pair and stores shortest distances.

Implements NetworKit::Centrality.

void NetworKit::DynBetweenness::update ( GraphEvent  e)
overridevirtual

Updates the betweenness centralities after an edge insertions on the graph.

Notice: it works only with edge insertions.

Parameters
eThe edge insertions.

Implements NetworKit::DynAlgorithm.

void NetworKit::DynBetweenness::updateBatch ( const std::vector< GraphEvent > &  batch)
overridevirtual

Updates the betweenness centralities after a batch of edge insertions on the graph.

Notice: it works only with edge insertions.

Parameters
batchThe batch of edge insertions.

Implements NetworKit::DynAlgorithm.

count NetworKit::DynBetweenness::visPairs ( )

Returns number of visited pairs.
