从6(a)和图6(b)和图6(c)的标准差的分布可以看出，图6(a)和

It can be seen from the distribution of standard deviations in 6(a) and Figs. 6(b) and 6(c) that the standard deviations of Figs. 6(a) and 6(c) are the lowest, while the standard deviation of 6(b) Although the difference calculation result is not the lowest, it is relatively not the worst, indicating that the stability of the IGOA calculation result is relatively the best.

It can be seen from the distribution of the standard deviation in Figure 6 (a), Figure 6 (b) and Figure 6 (c), that the standard deviation in Figure 6 (a) and Figure 6 (c) is the lowest, and the calculation result of the standard deviation in Figure 6 (b) is not the lowest, but it is relatively not the worst, indicating that the stability of the calculation result of IGOA is relatively the best.<br>
