WHATS NEW

v1.4.0 ? in preparation

SKILLS

Skills can now be included easily (see for example https://github.com/jsprit/jsprit/blob/master/jsprit-examples/src/main/java/jsprit/examples/SolomonWithSkillsExample.java). It lets you assign hard requirements to jobs and vehicles/drivers. For example, a technician requires a screwdriver to serve customer A or your vehicle requires a loading bridge to unload freight at customer B etc.. You can add an arbitrary number of skills to jobs and vehicles.

To enable the algorithm to consider skills, you need to use core.algorithm.VehicleRoutingAlgorithmBuilder as follows:


VehicleRoutingAlgorithmBuilder vraBuilder = new VehicleRoutingAlgorithmBuilder(skillProblem,yourConfig);
vraBuilder.addCoreConstraints();
vraBuilder.addDefaultCostCalculators();
           
StateManager stateManager = new StateManager(skillProblem);
stateManager.updateSkillStates();

ConstraintManager constraintManager = new ConstraintManager(skillProblem,stateManager);
constraintManager.addSkillsConstraint();

VehicleRoutingAlgorithm vra = vraBuilder.build();

UNASSIGNED JOB LIST

new feature: unassigned job list

STATEMANAGER

StateFactory.createId(String name) moved to core.algorithm.state.StateManager.createStateId(String name)
StateFactory moved from core.problem.solution.route.state.StateFactory to core.algorithm.state.InternalStates
StateId moved from core.problem.route.state.StateFactory.StateId to core.algorithm.state.StateId
StateFactory.createId(String name) is not accessible anymore
constructor new StateManager(VehicleRoutingTransportCosts costs) does not exist anymore, but is new StateManager(VehicleRoutingProblem vrp)
StateManager.addDefault... methods do not exists anymore. Client must now decide what to do when state does not exist.
deprecated core.problem.VehicleRoutingProblem.Builder.addVehicle(Vehicle v) and added core.problem.VehicleRoutingProblem.Builder.addVehicle(AbstractVehicle v)
deprecated core.problem.VehicleRoutingProblem.Builder.addJob(Job j) and added core.problem.VehicleRoutingProblem.Builder.addJob(AbstractJob j)

LOGGER

migrated from log4j1x to log4j2
