So this is trying to be a bruteforce method to a variation of the TSP. In this variation you start at a certain warehouse and you have a weight limit, you must pick up all of the packages at a warehouse and must take the roads from that warehouse only and after you deliver all of the packages you have to return to the starting warehouse. But I get stack overflow (how funny) from the method bellow, probably an infinite loop I haven’t caught.

Tried ChatGPT. Didn’t work.

Here is the code:

`public List<List> InitialTrip(List warehouses)
{
List<List> trails = new List<List>();

    Trip(this, warehouses, trails);

    return trails;
}

private void Trip(Bus bus, List<Warehouse> warehouses, List<List<string>> trails)
{
    if (bus.emptyWarehouses == warehouses.Count && bus.CurrentWarehouse.Name == bus.startingWarehouseName)
    {
        trails.Add(new List<string>(bus.Trail));
        return;
    }

    foreach (Road road in bus.CurrentWarehouse.Roads)
    {
        Bus busCopy = new Bus(bus);

        busCopy.UnloadPackages();
        if (busCopy.CanLoadPackages(busCopy.CurrentWarehouse.PickPacks))
        {
            busCopy.LoadPackages();
        }
        else
        {
            continue;
        }

        if (busCopy.CurrentWarehouse.PickPacks.Count == 0 && busCopy.CurrentWarehouse.DropPacks.Count == 0)
        {
            busCopy.emptyWarehouses++;
        }

        string previousWarehouse = busCopy.CurrentWarehouse.Name;
        busCopy.Trail.Add(road.End);
        busCopy.MoveToWarehouse(Warehouse.FindByName(road.End, warehouses));

        Trip(busCopy, warehouses, trails);

        // Restore the busCopy state
        busCopy.Trail.RemoveAt(busCopy.Trail.Count - 1);
        busCopy.MoveToWarehouse(Warehouse.FindByName(previousWarehouse, warehouses));
    }
}

public Bus(Bus busCopy)
{
    CurrentWarehouse = busCopy.CurrentWarehouse;
    startingWarehouseName = busCopy.startingWarehouseName;
    lastVisitedWarehouse = busCopy.lastVisitedWarehouse;
    emptyWarehouses = busCopy.emptyWarehouses;
    WeightLimit = busCopy.WeightLimit;
    CurrentWeight = busCopy.CurrentWeight;
    Packages = new List<Package>(busCopy.Packages);
    Trail = new List<string>(busCopy.Trail);
