| 23 | This type is a TSP tour visitor. It supplies the OutputIterator with the vertices of the tour and | |
| 24 | records the total length of the tour. | |
| 25 | ||
| 26 | <h3>Example</h3> | |
| 27 | ||
| 28 | <pre> | |
| 29 | double d(0.0); | |
| 30 | std::vector<Vertex> c; | |
| 31 | boost::metric_tsp_approx | |
| 32 | (g, get(edge_weight, g), | |
| 33 | make_tsp_tour_len_visitor(g, std::back_inserter(c), d, get(edge_weight, g))); | |
