- collect_data_items respects the minimum vehicle limits
- linking_relations can be grouped in collect_items
- split_solve represents services w multiple points
- Vroom can handle simplified setup durations
- Vroom can handle shipments as relation
- max_split_size prevents only optim-sync and Vroom can be called for sub-rpoblems
- small quality and linter fixes
Simplify asserts Prepare Vroom for shipment relation implementation Fix linter warnings Remove dead code Improve dev and test error messages
s.setup_duration, v.coef_setup, v.additional_setup can be simplified: IF all services at point p has the same setup_duration_p, and all vehicles with time matrix t have the same coef_setup_t and additional_setup_t THEN each time matrix t can be modified so that for all pairs of i and p t'_ip = t_ip + coef_setup_t * setup_duration_p + additional_setup_t. Basically, arriving point p takes longer to include the setup modifiers. This way solvers like Vroom can be used even if there is setup duration.
representative_vrp represents the original VRP by merging all points belonging to the same vehicle_cluster (coming from the first split) in to several points -- one is the mean and the remaining are the extreme points of all services of vehicle v. This way clustering can take into account the distribution of the original services.
IF the relations are completely compatible. For shipments this means that the pickup and delivery locations and skills are the same.
