Now, all the examples access the vertices by their number of generation.

I have created a vertex property of names.

How can I access the vertices by such property (without find_vertex).

You must create a dictionary that does the mapping: vertices = dict((name[v], v) for v in g.vertices()) The reason why this is not built-in is because the property map values are not in general unique. -- Tiago de Paula Peixoto <tiago@skewed.de>
