Under a lot of experiments with different data sets, the algorithm uses " block-move " neighborhood which is better than shift neighborhood and swap neighborhood. Another contribution of this paper is the detailed experiments results of comparing PILS with many other vehicle schedule algorithms. 该算法对当前邻域变换的方式选择是通过不同数据集下的大量实验,其结果显示块移动的邻域要优于交换邻域和移动邻域。
