CGAL 6.0 - CGAL and the Boost Graph Library
|
Concept from the Boost Graph Library. See https://www.boost.org/libs/graph/doc/EdgeListGraph.html.
The concept EdgeListGraph refines the concept Graph and adds the requirement for traversal of all edges in a graph.

returns an upper bound of the number of edges of the graph.
num_edges() may return a number larger than std::distance(edges(g).first, edges(g).second). This is the case for implementations only marking edges deleted in the edge container.
