城际仓储选址通常可以转化为顶点覆盖问题,顶点覆盖问题是一种经典的NP难问题.针对最小权重 3 路顶点覆盖问题,设计了基于边权和顶点度的贪心策略,构建了 1 个两阶段的最小权重 3 路顶点覆盖算法.通过与 2 种较优的最小权重 3路顶点覆盖算法进行对比实验分析可知,本文提出的算法在城际物流仓储选址问题中具有较好的效果,最小权重和分别减少了3.34和1.13 个百分点.
Minimum weight 3-path vertex cover algorithm based on edge weighting
Inter-city warehousing site selection can usually be transformed into vertex cover problem,which is a classical NP-hard problem.For the minimum weight 3-path vertex cover problem,this paper designs a greedy strategy based on edge weight and vertex degree,and constructs a two-stage minimum weight 3-path vertex cover algorithm.By comparative experiment and analysis with two better minimum weight 3-path vertex cover algorithms,it can be seen that the algorithm proposed in this paper has a better effect in the inter-city logistics warehousing site selection problem,and the sum of minimum weight is reduced by 3.34 and 1.13 percentage points respectively.
