The costs of one-way flights between these locations are listed below:
a) Represent this traveling salesman problem with a complete graph showing the prices of the flights on the appropriate edges.b) Use the Nearest Neighbor method to approximate the optimal route for Devin to travel to each city and return to Providence. Give the cost of the route found.c) Randomly select another
route from Providence to the other cities and compute the cost of this route. Compare this cost to the cost found in part (b). What will be an ideal response?
