| <H1>TSP Tour Visitor concept</H1> |
| |
| This concept defines the visitor interface for <a |
| href="./metric_tsp_approx.html"><tt>metric_tsp_approx()</tt></a> |
| and related algorithms. The user can create a class that matches this |
| interface, and then pass objects of the class into |
| <tt>metric_tsp_approx()</tt> to augment the actions taken during |
| the search. |
