Re: [rules-users] Drools Planner: Vehicle routing problems

Hi Ge0ffrey, I mean the initialised solution Sorry, the number is just the number of milliseconds as returns by the new solution event so at this point the solution is valid, its later steps where I get the problem ? Indeed this is my problem. There seems to be more than 1 instance of B. I've debugged my example code, and then issue seems to be: https://github.com/davidglassborow/drools-planner/blob/vehicle_routing/dr... The solver seems to be assigning the visit to be before itself ! If you look at: https://github.com/davidglassborow/drools-planner/blob/vehicle_routing/dr... you'll see I have added a check to your Visit.java, which doesn't display the same problem. So I'm not sure what is happening, domain objects seems to be cloned and assigned to themselves. I have checked and double-checked the code inline with your TSP example, I'm sure it's nothing stupid I've done but can't for the life of me see anything wrong. If you download the branch, and run the VehicleRoutingHelloWorld class, you'll see the problem occuring. What did you need to change to get that to work ? Was it just a case of adding another domicile, and then removing the return to domicile cost rule ?
