Approximation Hardness of Graphic TSP on Cubic Graphs
Marek Karpinski and Richard Schmied [Download PostScript] [Download PDF] We prove explicit approximation hardness results for the Graphic TSP on cubic and subcubic graphs as well as the new inapproximability bounds for the corresponding instances of the (1,2)-TSP. The proof technique uses new modular constructions of simulating gadgets for the restricted cubic and subcubic instances. The modular constructions used in the paper could be also of independent interest. |
