On Parametric Formulations for the Asymmetric Traveling Salesman Problem: A Comparative Analysis of the d-MTZ, d-DL, and b-SCF Formulations

This paper introduces and analyzes families of parametric formulations for the Asymmetric Traveling Salesman Problem (ATSP), demonstrating that the classic MTZ, DL, and SCF formulations are specific instances within these families and that no single formulation consistently dominates the others.
