Re: [boost] [BGL] Multithread problem inserting edges and exploring the same graph

That only works if both graphs are adjacency_lists and you have control over the graph types. I would personally just make:

template <typename T> struct from_first_graph {T data;}; template <typename T> struct from_second_graph {T data;};

and then have my variants be:

boost::variant<from_first_graph<graph_traits<First>::vertex_descriptor>, from_second_graph<graph_traits<Second>::vertex_descriptor>

...

and the same for edge descriptors. This will disambiguate the types for arbitrary graphs.

It seems a very good idea to me. I'm trying it. I'll tell you about it ASAP. Thanks again, Cosimo Calabrese.
