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。-In the midst of the waters, the fish are often on their own or trailing other fish to find places with more nutrients, and therefore the fish survive the largest number of places in the waters in general is the place where most of the nutrients, artificial fish swarm algorithm is based on this characteristic, by constructing artificial fish to imitate the feeding of the fish stocks.
