A city planner wants to work with community leaders to develop a system of walker-friendly paths between the city's five parks. Since cost is an issue, the planner collects data on the cost of each park-to-park route. The planner uses the Nearest Neighbor method to determine an estimate of a least cost system of sidewalks that would allow a walker to visit each park once and return to the park where the walker has parked his/her car. The weighted graph below shows the cost of each possible path in thousands of dollars.
