在一片水域中，鱼往往能自行或尾随其他鱼找到营养物质多的地方，因而鱼生存数目最多的地方一般就是本水域中营养物质最多的地方，人工鱼群算法就是根据这一特点，通过构造人工鱼来模仿鱼群的觅食、聚群及追尾行为，从而实现寻优。-In the midst of the waters, the fish often can be found on their own or trailing other fish nutrients in many places, so that the largest number of fish in general is where the survival of most of the waters where nutrients, AFSA is based on this feature, by constructing artificial feeding fish to imitate, clusters and rear-end behavior of fish in order to achieve optimization.
