5. Consider the distribution problem from a warehouse to several customers. The following table shows the locations (coordinates) and demands of the customers. The warehouse is located at (40,40). a) Suppose that the truck capacity is 100 (all demand can be delivered by one truck). Find a route for the truck using the nearest neighbor heuristic. b) Now, consider the case where the capacity of a truck is only 50. Use Clark-Wright heuristic to find routes for multiple trucks. Compare the total travel distances you obtained in parts (a) and (b)
