摘要:

针对传统多目标粒子群算法容易早熟的问题,提出了一种基于多样性控制的多目标粒子群算法。该算法采用一种基于权值向量的多样性评价指标来度量算法在每一次迭代时的种群多样性,并根据评估值来自适应地控制算法的进化过程。为了保证种群的多样性,采用一种基于Steffensen方法的自适应变异策略对外部种群进行更新。通过自适应地选择粒子的全局最优位置来实现种群多样性与收敛性之间的平衡。将该算法与几种常用的多目标进化算法在一系列标准测试函数上进行了仿真实验,统计结果证明了所提算法的有效性。

Abstract:

For solving the premature in traditional multiobjective particle swarm optimization,a multi-objective particle swarm optimization based on diversity control is proposed.The proposed algorithm utilizes a diversity metric,which is based on weight vectors,to evaluate the population diversity in each generation and control the evolution process of the algorithm adaptively.To maintain population diversity,an adaptive mutation strategy based on Steffensen’s method is adopted to update the repository population.With the purpose of balancing the population diversity and convergence,the global best positions of particles areselected adaptively.This algorithm is compared with several widely used multiobjective evolutionary algorithms on a set of benchmark test problems in the experimental part.Statistical results demonstrate the effectiveness of the proposed algorithm.

Key words: multiobjective optimization, particle swarm optimization, adaptive algorithms, diversity control, Steffensen’s method
