A clean-up crew is stationed at facility D and wants to take the shortest route to each site. They usually clean up facilities C, E, A and F on the same day and therefore want the shortest route from D to each facility

Recommend a route for the crew to leave from D, clean up each facility one after the other, and return to facility D. (Assume all paths are accessible.)


Answer: D to E to F to C to A to D. Total distance = 47. This is really a small version of the traveling salesman problem. Doing the minimal spanning tree prior to this problem may be helpful.
