摘要:
二次旅行商问题(QTSP)是旅行商问题的推广,其中巡回路线中所有连续三个客户共同决定旅行成本。我们为QTSP提出了紧凑的优化模型,包括混合整数二次规划(MIQP)、混合整数线性规划(MILP)、约束规划(CP)和领域无关动态规划(DIDP)。实验结果表明,当问题规模足够大时,DIDP模型在最优性差距和解质量上优于其他方法。
英文摘要:
The quadratic traveling salesperson problem (QTSP) is a generalization of the traveling salesperson problem, in which all triples of consecutive customers in a tour determine the travel cost. We propose compact optimization models for QTSP in mixed-integer quadratic programming (MIQP), mixed-integer linear programming (MILP), constraint programming (CP), and domain-independent dynamic programming (DIDP). Our experimental results demonstrate that the DIDP model performs better than other approaches in optimality gap and solution quality when the problem size is large enough.
