6. The Wolverine Manufacturing Company owns and operates a number of computer-controlled machines that can be programmed to perform precise drilling and machining operations. The company is currently programming their drilling machine for a job that requires nine holes to be drilled in precise locations on a flat fiberglass panel that is used in the production of a popular automobile. After each hole is drilled, the machine will automatically retract the drill bit, and move it to the next location until all the holes have been drilled. Because the machine will be required to repeat this process for millions of panels, Wolverine is interested in making sure that it programs the machine to drill the series of holes in the most efficient manner. In particular, they want to minimize the total distance the drill bit must be moved in order to complete the nine drilling operations
