PyVRP is an open-source, state-of-the-art vehicle routing problem (VRP) solver. It currently supports VRPs with:

• Pickups and deliveries between depots and clients (capacitated VRP, VRP with simultaneous pickup and delivery, VRP with backhaul);

• Vehicles of different capacities, costs, shift durations, and maximum distance and duration constraints (heterogeneous fleet VRP);

• Time windows, client service durations, and release times (VRP with time windows and release times);

• Multiple depots (multi-depot VRP);

• Optional clients with prizes for visiting (prize collecting, team orienteering problem);

• Client groups imposing additional restrictions on multiple clients jointly (generalised VRP, VRP with multiple time windows).

The PyVRP package comes with pre-compiled binaries for Windows, Mac OS and Linux, and can thus be easily installed without requiring local compilation. It can be installed through pip via

pip install pyvrp
