Improving the Approximation Ratio for Capacitated Vehicle Routing
Copyright policy )Improving the Approximation Ratio for Capacitated Vehicle Routing
AbstractWe devise a new approximation algorithm for capacitated vehicle routing. Our algorithm yields a better approximation ratio for general capacitated vehicle routing as well as for the unit-demand case and the splittable variant. Our results hold in arbitrary metric spaces. This is the first improvement upon the classical tour partitioning algorithm by Haimovich and Rinnooy Kan (Math Oper Res 10:527–542, 1985) and Altinkemer and Gavish (Oper Res Lett 6:149–158, 1987).
