The Integrality Gap of the Traveling Salesman Problem is if the LP Solution Has at Most Non-zero Components
Tullio Villa, Eleonora Vercesi, Janos Barta +1
We address the classical Dantzig - Fulkerson - Johnson formulation of the symmetric metric Traveling Salesman Problem and study the integrality gap of its linear relaxation, namely…

On the integrality Gap of Small Asymmetric Traveling Salesman Problems: A Polyhedral and Computational Approach
Eleonora Vercesi, Janos Barta, Luca Maria Gambardella +2
In this paper, we investigate the integrality gap of the Asymmetric Traveling Salesman Problem (ATSP) with respect to the linear relaxation given by the Asymmetric Subtour Eliminat…
