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

Though newer “smart” infusion pumps are increasingly becoming more sophisticated, they cannot prevent all programming and administration errors. Health care professionals that use smart infusion pumps must still practice the rights of medication administration and have other professionals double-check all high-risk infusions.
