Constructor & Destructor Documentation

NodeExpulsor()

ogdf::planar_separators::NodeExpulsor::NodeExpulsor ( bool  balance = true )

inline

Constructor.

NE can either aggressively reduce separator size, even at the expense of violating the maximal size of 2/3 for one component, or only reduce separator size until the ratio is met exactly.

Parameters

balance

whether to keep the components balanced
