Consider a variation of the Vehicle Routing Problem in which the nodes have service deadlines; i.e., demand node i N must be visited before time i. The objective is still to minimize the cost of all routes, visiting each node exactly once, but now you must ensure that all routes are under capacity AND all nodes are visited before their service deadline. Show how you can adapt the savings method to solve this variation of the vehicle routing problem with service deadlines. Clearly define each step
