How to optimize a sequence for time constraints

Time constraints are defined using two parameters:

acc, which defines the time windows when the destination can be visited.
st, which defines "service time" - time spent at the given waypoint.

The following constraint allows visits on Mondays to Fridays between 12 PM and 6 PM. The service time is 15 minutes.

acc:mo12:00:00+02:00|fr18:00:00+02:00;st:900

To learn more about defining time constraints, see the API reference.

Example

The car journey starts in Duisburg-Ruhrort and the destination is the nearby Duisburg-Haefen. The route must pass through Zeche Zollverein, Kokerei Zollverein, and Muehlheim. The driver needs the fastest possible route.
