约束车辆路径问题随机解的比较

Comparison of Randomized Solutions for Constrained Vehicle Routing Problem

İbrahim Ethem Demirci, Şaziye Ece Özdemir, Oğuz Yayla

摘要:

本文研究了容量受限的车辆路径问题(CVRP)及其随机蒙特卡罗方法求解。为了解决CVRP,我们使用一些在实践中常用的伪随机数发生器。我们使用线性,多重递归,反演,和显式反演同余生成器,并获得随机数从每个CVRP提供一个路由。然后,我们比较了伪随机数发生器的性能相对于随机路由的总时间。我们还建立了一个开源的库github.com/iedmrc/binary-cws-mcs上解决CVRP基于蒙特卡洛的启发式方法。

英文摘要:

In this short paper, we study the capacity-constrained vehicle routing problem (CVRP) and its solution by randomized Monte Carlo methods. For solving CVRP we use some pseudorandom number generators commonly used in practice. We use linear, multiple-recursive, inversive, and explicit inversive congruential generators and obtain random numbers from each to provide a route for CVRP. Then we compare the performance of pseudorandom number generators with respect to the total time the random route takes. We also constructed an open-source library github.com/iedmrc/binary-cws-mcs on solving CVRP by Monte-Carlo based heuristic methods.
