Because of the finite sample size, the precise limit and derivative does not exist. However, the approximatederivative will provide insight into the game balance.
因为样本大小有限,精确极限和导数不存在,最近似的导数可以洞悉游戏平衡性。

The results of classical cases indicate that the sensitivity derivative gained by approximate method has good accuracy and the inverse design can be completed efficiently with reduced total CPU time.
