摘要
许多著名的组合优化问题都可在无向图的无环定向集合上表述。例如，具有特定直径约束的无环定向与顶点着色和频率分配问题的最优解密切相关。在本文中，我们引入了无环定向带路径约束的线性规划模型，并讨论其在求解顶点着色问题和某些频率分配问题版本中的应用。presented a study of the associated polytope, including proofs of which constraints of the formulation are facet-defining and the introduction of new classes of valid inequalities.
