Synopsis

This C++ template library implements directed and undirected graphs with constant-time random access to incident vertices and edges. Vertices and edges can always be indexed by contiguous integers as well as by STL-compliant random access iterators. This simplifies the implementation of algorithms for static graphs. In dynamic graphs (where vertices or edges can be removed), their changing integer indices can be followed, if necessary, via callbacks. Subgraphs are defined by subgraph masks.
