Examples of VehicleRoutingProblem

jsprit.core.problem.VehicleRoutingProblem
Contains and defines the vehicle routing problem.
A routing problem is defined as jobs, vehicles, costs and constraints.
To construct the problem, use VehicleRoutingProblem.Builder. Get an instance of this by using the static method VehicleRoutingProblem.Builder.newInstance().
By default, fleetSize is INFINITE, transport-costs are calculated as euclidean-distance (CrowFlyCosts), and activity-costs are set to zero. @author stefan schroeder
