AddOptimWithSetMatrices

Overview

This example app demonstrates the following features:

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

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

How to use the sample

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

How it works

1. Create a vrp::OrderList and add the orders to it. Each order needs to have a customer set; you can either add a new customer and then set it to the order, or you can use a previously created customer (see Get Customer example).
2. Create a vrp::ConfigurationParameters and set the distance 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 a vrp::Request that will be used to track the request status.
5. Call the addOptimization() method from vrp::Service using the request from 4.), the vrp::Optimization from 3.), and the progress listener.
6. After adding the optimization, monitor the request until it reaches a finished state. Once completed, retrieve the optimization results by calling the getSolution() method, which returns a vrp::RouteList containing the generated routes.

To display the orders and routes 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 orders, departures and destinations.
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.
