This algorithm improves the randomness when the traditional cross coverage select the initial covering point, and increase the generalization of covering by increasing the sample point contained in each coverage to reduce the number of coverage. 改进了传统交叉覆盖在覆盖初始点选取时的随机性,并通过增加每个覆盖所包含的样本点来减少覆盖数,从而增强了覆盖的泛化能力。
