In the GAFSA, global information is added to the artificial fish position updating process. The experimental results indicate that the optimization precision and the convergence speed of the proposed method are significantly improved when compared with those of the original AFSA. 在全局人工鱼群算法中,人工鱼的位置更新模式中加入了全局最优信息,仿真实验表明,论文中所提出的全局人工鱼群算法提高了人工鱼群算法的收敛速度和收敛精度。
