| 摘 要： | 针对传统人工鱼群算法的寻优精度不高、后期收敛速度慢且出现振荡现象的问题,提出一种自适应视野和步长的人工鱼群算法,该算法将两条人工鱼之间的距离作为视野,并将得到的视野乘以一个系数作为步长。随着鱼群的不断聚集,视野和步长相应地减小,有利于搜寻到最优点。实验结果表明,改进后的算法收敛速度更好、寻优精度更高。

| Abstract: | In view of such flaws as low accuracy, slow convergence rate and oscillation in the later stage which are commonly found in the traditional artificial fish swarm algorithm, a proposal has thus been made of an artificial fish swarm algorithm with adaptive visual field and step length. Taking the distance between the two artificial fish as the visual field, the proposed algorithm multiplies the obtained results by a coefficient as the step length. With the continuous accumulation of fish, the corresponding reduction in visual field and step length is conducive to locating the optimum point. The experimental results show that the improved algorithm is characterized with advantages of better convergence rate and higher accuracy. |
