Multi-objective PSO based on infeasibility degree and principle of endocrine

针对有约束条件的多目标优化问题,提出了一种求解带约束的基于内分泌思想的多目标粒子群算法。利用不可行度方法和约束主导原理指导进化过程中精英种群的选择操作和约束条件的处理,根据生物体激素调节机制中促激素和释放激素间的相互作用原理,考虑当前非劣解集中的个体对其最邻近的一类群体的监督控制,引入当前粒子的类全局最优位置来反映其所属类中最好位置粒子对当前粒子的影响。为验证多目标约束优化算法的有效性,对两个典型的多目标优化问题进行了仿真实验,仿真结果表明该算法能较大概率地获得多目标约束优化问题的可行Pareto最优解。

For multi-objective optimization problems with constraint,a new Particle Swarm Optimization（PSO） algorithm for multi-objective with constraint was proposed.In the method,the constraints and the selection for elite swarm were disposed by infeasibility degree and domain principle.According to the control and supervised principle between Simulation Hormone（SH） and Releasing Hormone（RH） in endocrine system,and considering the supervision and control of individual in the non-dominated set for the nearest class of swarm,the global optimization position of class was used to generate the new position for particles.In order to verify the effectiveness of the given method,two benchmark multi-objective problems were simulated by the given method,NSGA-II and MOPSO-CD.The results indicate that the given method can find feasible Pareto solutions with a large probability.
