How to … implement a new VRP Evaluator

Goals

One way to implement a new VPR variant is by extending the VRPEvaluator. This is a suitable possibility if the VRP variant does not require additional model data or decision variables. A VRPEvaluator is responsible for evaluating a solution candidate which contains a set of tours. By extending the VRPEvaluator, it is possible to interpret the available information of a specific problem instance differently.

After this tutorial you will be able to implement your own VRP variants that only require extending the VRPEvaluator. You will also have a basic understanding of the concepts and architecture concerning the VRPEvaluator and related components.
