Title: Divisors on M_{0,n} and linear programming polytopes
Abstract: We define the polytopes of effective boundary representations for divisors on M_{0,n}. We show certain functoriality properties of these polytopes under the forgetful maps of marked points. We compute these polytopes for log canonical class, psi classes and their pullbacks by forgetful maps. Lastly, as an application, we provide a Minkowski-like decomposition of Held-Karp relaxation polytope of symmetric traveling salesman problem.
