<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.
