Pragmatic format aims to model a multiple VRP variants through single problem and solution model schemas which are described in details in next sections.
There is no limit on problem size, solver should be able to solve problems with thousands of jobs in fairly reasonable amount of time depending on your termination criteria (e.g. time or amount of iterations/generations). However, exact performance depends on VRP variant (e.g. VRPPD is slower than CVRPTW).
Although results seems to be comparable with alternative solutions, default metaheuristic still can be improved.
A various examples can be found in pragmatic examples section.
