Add optimization with set matrices

Add an optimization with custom matrices and display the solution on the map.

Add optimization with set matrices - stops

Add optimization with set matrices - solution

Use case

Create an optimization where the time and distance matrice values are set by the user.

How to use the sample

First, get an API key token, see the Getting Started guide.

Download the Maps & Navigation SDK for C++ archive file for Linux or Windows

When you run the sample, an optimization will be saved, the solution will be returned and showed on map.

How it works

  1. Create a vrp::StopList and add the stops to it.

  2. Create a vrp::ConfigurationParameters and set the distnace unit, the matrices build type to MBT_Set and the matrices to it.

  3. Create a vrp::Optimization and set the objects created at 1.) and 2.) to it.

  4. Create a ProgressListener, vrp::Service and vrp::RouteList, in which the solution will be returned.

  5. Call the addOptimization() method from vrp::Service using the list from 4.), the `vrp::Optimization from 3.) and the progress listener.

  6. Once the operation completes, the list from 4.) will contain the solution of the optimization.

To display the locations and territories on the map

  1. Create a MapServiceListener, OpenGLContext and MapView.

  2. Create a LandmarkList, CoordinatesList and PolygonGeographicArea.

  3. Instruct the MapView to highlight the LandmarkList from 2.) to print the stops.

  4. Instruct the MapView to center on the PolygonGeographicArea.

  5. Create a MarkerCollection of type Polyline and add the route’s shape to it.

  6. Set the newly created MarkerCollection in the markers collections of the map view preferences.

  7. Allow the application to run until the map view is fully loaded.
