Abstract

The invention discloses a conveying path combination optimization method based on a stage structured predator-prey model. Supposing that multiple animal populations grow in an ecological system, and each population is divided into two stage types of adult populations and young populations; the adult populations produce their young populations at a certain birth rate, and the young populations grow up into the adult populations after a period of time; the influence of mutual competition for living resources between the populations is shown in the influence on the characteristics; the population having larger proportion in all the populations has higher influence, and the population spreads its influence to other populations; the advantageous and strong populations spread their high quality characteristics to other populations; and if one population is continuously influenced by other populations, its growth state continuously changes, and the global optimal solution of the problem of conveying path combination optimization can be rapidly determined by using the change and the multi-population predator-prey system model having the stage structure.

Description
