WebIn 1976, Christofides and Serdyukov independently of each other made a big advance in this direction: [9] the Christofides-Serdyukov algorithm yields a solution that, in the worst case, is at most 1.5 times longer than the optimal solution. As the algorithm was simple and quick, many hoped it would give way to a near optimal solution method.
