◆ AUTOMATIC

◆ BEST_PICKUP_DELIVERY_PAIR

◆ BEST_PICKUP_DELIVERY_PAIR_MULTITOUR

com.google.ortools.constraintsolver.RoutingSearchParameters.PairInsertionStrategy.BEST_PICKUP_DELIVERY_PAIR_MULTITOUR =(3) 
Only consider insertion positions that are compatible with the multitour
property, meaning a series of pickups may only start when the vehicle
is not carrying any delivery. This setting is designed to explore much
less possibilities than the full BEST_PICKUP_DELIVERY_PAIR.
Order by increasing by cost(pickup) + cost(delivery).
