人工鱼群算法的实证研究

Empirical Study of Artificial Fish Swarm Algorithm

Reza Azizi

摘要:

人工鱼群算法是一种基于种群和随机搜索的群体智能优化算法。为了达到可接受的结果,人工鱼群算法中有许多参数需要调整。在这些参数中,视觉和步长是非常重要的,因为人工鱼基本上基于这些参数移动。在标准AFSA中,这两个参数保持不变,直到算法终止。这些参数的取值较大时,算法的全局搜索能力增强;取值较小时,算法的局部搜索能力增强。在本文中,我们实证研究的性能AFSA和不同的方法来平衡局部和全局的探索进行了测试的基础上自适应修改的视觉和步骤在算法执行。所提出的方法进行了评估的基础上,四个著名的基准功能。实验结果表明,相当积极的影响AFSA的性能。

英文摘要:

Artificial fish swarm algorithm (AFSA) is one of the swarm intelligence optimization algorithms that works based on population and stochastic search. In order to achieve acceptable result, there are many parameters needs to be adjusted in AFSA. Among these parameters, visual and step are very significant in view of the fact that artificial fish basically move based on these parameters. In standard AFSA, these two parameters remain constant until the algorithm termination. Large values of these parameters increase the capability of algorithm in global search, while small values improve the local search ability of the algorithm. In this paper, we empirically study the performance of the AFSA and different approaches to balance between local and global exploration have been tested based on the adaptive modification of visual and step during algorithm execution. The proposed approaches have been evaluated based on the four well-known benchmark functions. Experimental results show considerable positive impact on the performance of AFSA.
