Why do you not want to use graph.vertices?

Hello graphGang!

I have some relative simple (but also quiet practical) questions for you.

1. How can you access the indices of the nodes of an arbitrary graph?
        - You can not assume that they are equal to the "range(graph.num_vertices())”.  For instance, imagine that we are dealing with a filtered version of some graph.
        - Is there another way than invoking the iterator graph.vertices() ?

The application I have at hand is to sample pairs of nodes of a graph and apply a function like the shortest distance between them (and I would like to do that fast).

2. I think that when it comes to sampling/accessing of the indices of edges there is not a better way than invoking the iterator graph.edges() and work with its output. Correct?

Thanks a lot,
H.
