* <p>diff. options of VrphType yields to different problem types for
* - vrphe with infinite fleet, i.e. different types with different variable costs and infinite number of vehicles of each type
* - vrphe with finite fleet, i.e. different types with different variable costs and finite number of vehicles of each type
* - vfm, different types with different fixed costs
* - vfmvrc different types with different fixed costs and variable costs
* <p>See {@link VrphType} what kind of problems can be generated
*
* <p>cxxx3-cxxx6 do not have variable costs and nuVehicle, thus they can only be used for vfm.
* <p>Note that c20_3-c20_6 do not have variable costs and a limited nuVehicle, thus they can only be used for FSMF.
