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.



The repetitive nearest-neighbor tour starting with vertex A is given by:
◦ A, B, C, D, E, A.
◦ A, E, C, D, B, A.
◦ A, D, B, E, C, A.
◦ A, C, D, B, E, A.
◦ none of these

The shortest trip in this situation can be found using
◦ the cheapest-link algorithm.
◦ the nearest-neighbor algorithm.
◦ both the nearest-neighbor and the cheapest-link algorithms.
◦ the repetitive nearest-neighbor algorithm.
◦ all of these algorithms give the shortest trip in this situation.

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:
◦ 28 miles.
◦ 68 miles.
◦ 58 miles.
◦ 57 miles.
◦ none of these

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
