    @GeoffreyDeSmet can you pls advise if, OptaPlanner is good for solving a problem for EV drivers. I need to plan a route from A to D, and stop on B,C or only B because B is fast-charging. something like that.

      Timefold (= OptaPlanner++) is often used for that kind of cases. Model wise you let it decided the route without recharging, and force "just in time automatic nearest recharging" through a shadow variable. Basically if I can get from start to Z to A without recharging, fine. If I can't get to D any more without recharging, automatically active the shadow var on D to state that it will first recharge at the nearest recharger (B).

    Hi. Would you tell me how to edit the source code for Vehicle Routing? I mean, the exact archive. I'm trying to change the map and edit the nodes but I can't seem to find the right code to edit. Is there a way of editing on the web version? I get to open it at the host but I can't edit that.

    Hi, do you know how to dynamically define the score type of a penalty in the constraints of the solver?

      Yes, see ConstraintConfiguration in the OptaPlanner/Timefold docs.

    How can you optimise for bicycle, does it support other graphhopper profiles?

      In optaweb-vehilce-routing, it's a matter of fetching the travelDuration matrix (or distance matrix) on basis of a bicycle instead of a car.

    What's the difference between Optaplanner and OptyPy?

    How do i use optaplanner with the map of Brazil? For me, the South America option does not appear.

      In optaweb-vehicle-routing demo application, run runLocally.sh --help to see info on how to select your geographical region.

    How to run this? For me it's opening on browser(local host), but I can't edit nodes like you can do in real time. How to download it locally? and where to access code?
    Is optaPlanner supports CVRPR(capacitated vehicle routing problem with revisits)?

      If you run it from source, you can edit the source code. In Timefold quickstarts we're making this easier by providing curl commands to send the json dataset to the VRP rest API.
      Revists are possible, but you'll currently have to add that revisit constrain yourself.
