说明：  免疫优化——克隆选择算法求解模型的最优解（二维）函数， 图形显示部分包括了初始分布图和最终位置分布图，能明显观测到抗体最终集中在局部最小值部分
(Immune optimization - clonal selection algorithm to solve the optimal solution (two-dimensional) function of the model. The graphical display part includes the initial distribution map and the final position distribution map. It can be observed that the antibody finally concentrates in the local minimum part.)
