Is reverse_graph<> in Boost::Graph Library, read-only?

It appears to be read-only. It should be possible to add mutation; it just isn't there yet. Do you need that feature?

Yes. My program build two trees in the same graph. First tree is "forward". Second tree is "backward": build by the same algorithm, but in reverse order. So I need add_vertex and add_edge for reverse trees. I wrote them this way (please look if I'm correct - because I'm a newbie and can make stupid errors).

Do those versions work? I forgot whether edge_descriptors in the original graph are implicitly convertible to edge_descriptors in the reverse_graph; your implementations require that. Your code would be easy to fix for the other case, though. Could you please add in the rest of the mutating functions so that I can add your code to BGL? -- Jeremiah Willcock
