Deleting arcs (7,8) and (10, 9) flips the subpath from 8 to 10. Two TSP tours are called 3-adjacent if one can be obtained from the other by deleting three edges and adding three edges. 3-opt heuristic. Look for a 3-adjacent tour with lower cost than the current tour. If one is found, then it replaces the current tour.
