Evolutionary Algorithm for Solving the Problem of Grazing Yak Population in Three Rivers Source Region

Abstract

The three rivers source region is a complex ecosystem with alpine grassland characteristics. The animal husbandry is mainly based on Breeding yak. Breeding yak is the mainstay of the herdsmen's production and life. The model of this paper mainly through the yak population structure of the relevant factors, using the evolutionary algorithm, taking the maximum net monetary income as the objective function, the optimal yaks’ sales scheme is given without destroying the ecological environment. The experimental results show the validity and practicability of the model and evolutionary algorithm. This study can provide guidance for the structure adjustment and decision-making in three rivers source area.
