Instance File

To enhance readability and interpretability by other programs, instead of using ad-hoc tab separated file formats in traditional VRP benchmarks, the Vehicle Routing Scheduler Library converts them into standard XML format, as shown in Figure 3. In current implementation, all benchmark instances or user-created problem instances (e.g. map-based problem instances) are stored in XML file format, and the library only reads XML files for VRP input.
