多条旅行商问题

The multi-stripe travelling salesman problem

Eranda Cela, Vladimir Deineko, Gerhard J. Woeginger

摘要:

在经典的旅行推销员问题(TSP)中,目标函数是沿着旅行路线从一个城市到下一个城市的旅行费用之和。在q大于1的q条TSP中,目标函数将从一个城市到下一个q个城市的旅行成本相加。由此产生的q-条纹TSP推广的TSP和形式的特殊情况下的二次分配问题。我们分析的计算复杂性的q-条纹TSP的各类特殊结构的距离矩阵。我们得出NP-硬度的结果,以及多项式可解的情况下。我们的一个主要结果将著名的Kalmanson定理从经典TSP推广到q-条纹TSP。

英文摘要:

In the classical Travelling Salesman Problem (TSP), the objective function sums the costs for travelling from one city to the next city along the tour. In the q-stripe TSP with q larger than 1, the objective function sums the costs for travelling from one city to each of the next q cities along the tour. The resulting q-stripe TSP generalizes the TSP and forms a special case of the quadratic assignment problem. We analyze the computational complexity of the q-stripe TSP for various classes of specially structured distance matrices. We derive NP-hardness results as well as polyomially solvable cases. One of our main results generalizes a well-known theorem of Kalmanson from the classical TSP to the q-stripe TSP.
