You are assigned the edge weight matrix for a complete graph. Determine an approximation to the minimum weight tour using the Nearest neighbor heuristic. Also, show one attempt of reducing the tour weight using the 2-change heuristic for the tour obtained. Show all the work as well as clearly indicate the tour and its weight before and after the attempt of using the 2-change heuristic.
