To overcome premature searching by standard particle swarm optimization(PSO)algorithm for the great loss of population diversity,a novel adaptive PSO is proposed,which can dynamically change inertia weight coefficients by the measure of population diversity.
针对标准粒子群算法在进化过程中种群多样性降低而早熟的问题,提出了一种根据种群多样性测度动态改变惯性权重系数的自适应粒子群算法,该算法能够平衡算法的全局探索和局部开发能力,不仅有效地避免早熟,而且具有较快的收敛速度。
