说明：  自抗扰算法仿真程序，算法学习使用，适合理论分析(Auto disturbance rejection algorithm simulation program, algorithm learning and use, suitable for theoretical analysis)

ev-MOGA Multiobjective Evolutionary Algorithm has been developed by the Predictive Control and Heuristic optimization Group at Universitat Politècnica de València. ev-MOGA is an elitist multi-objective evolutionary algorithm based on the concept of epsilon dominance. ev-MOGA, tries to obtain a good approximation to the Pareto Front in a smart distributed manner with limited memory resources. It also adjusts the limits of the Pareto front dynamically.
