Hi,

I am trying to use metric_tsp_approx on a graph defined as :

typedef adjacency_list Graph;

City contains the vertex id and Road the edge weight. After reading the documentation, I arrived to :

  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)));

After your first named argument, you need to use named arguments for the rest of the argument list: metric_tsp_approx(g_init,     weight_map(...).vertex_index_map(...).visitor(...)); Fixing that might fix your compilation errors. -- Jeremiah Willcock
