Jeremiah : could you explain why you need named arguments ? I find
that very confusing !
Also, I'm having trouble creating a visitor. I tried :

metric_tsp_approx(g_init, 
    weight_map(get(&Road::length, g_init)).vertex_index_map(get(&City::id, g_init))
    .make_tsp_tour_visitor(back_inserter(c)));

But compiling raises the error :
     has no member named ‘make_tsp_tour_visitor’

Should I create a class for the visitor ? 

Albert : I have included a small example as an attached file.
