If your route contains five or more stops, an Optimize link is displayed on the Routing dialog box.
Click the link to optimize your route. Optimizing a route reorders the stops (except for the start and end points) to create the shortest or quickest route that includes all stops.
To specify which criteria to use when optimizing a route, click the Settings tab .
The routing method also determines the route between stops, even if you are not optimizing the route.
