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.
