Planarity checking, embedding, drawing and coloring.


template<typename GR >
bool checkPlanarity (const GR &graph)
 Planarity checking of an undirected simple graph.

Function Documentation

bool lemon::checkPlanarity ( const GR &  graph)

This function implements the Boyer-Myrvold algorithm for planarity checking of an undirected simple graph. It is a simplified version of the PlanarEmbedding algorithm class because neither the embedding nor the Kuratowski subdivisons are computed.
