Chapter 6, Problem 40E
The Platonic Cowboys are a country and western band based in Nashville. The Cowboys are planning a concert tour to the seven cities in the mileage chart shown in Fig. 6-46.
a. Find the nearest-neighbor tour with Nashville as the starting city. What is the total length of this tour?
b. Find the nearest-neighbor tour using St. Louis as the starting city. Write the tour as it would be traveled by the band, which must start and end the tour in Nashville. What is the total length of this tour?
