A mail truck must deliver packages to 5 different homes (A, B, C, D, and E). The trip must start and end at A. The graph below shows the distances (in miles) between locations. We want to minimize the total distance traveled.
Using both the cheapest-link and the repetitive nearest-neighbor algorithm, the length of the shortest trip we can find (without using brute force) is:
A. 57 miles. B. 28 miles. C. 58 miles. D. 68 miles. E. none of these
