You work for an airline. You must design a flight path for a flight from Tokyo to New York. The flight needs to stop at two to three cities to pick up and drop off passengers. Your CEO has asked you to provide her with answers to the following: What is the fastest way path? Which is the least expensive path? Which is the most profitable path? Structure a problem space on how you'd solve this problem. What would you define as the cost? Because there are so many possibilities of which cities to stop in, how would you determine the best routes?
