VehicleRoutingAlgorithmBuilder class is not present in release 1.7-RC1 , That's why I am unable to use code :
VehicleRoutingAlgorithmBuilder vraBuilder = new VehicleRoutingAlgorithmBuilder(vrp, "algorithmConfig_solomon.xml");
vraBuilder.addCoreConstraints();
vraBuilder.setNuOfThreads(4);
VehicleRoutingAlgorithm vra = vraBuilder.build();
Is there any other way to re-write the above code?
