摘要

针对蜻蜓算法初始种群随机性大、算法权重参数调节困难导致算法收敛精度低,后期种群收缩限制导致算法活力不足、收敛速度慢等问题,提出一种基于混沌映射和差分进化的改进蜻蜓算法.通过Tent混沌映射,使种群初始化分布均匀;改进对齐权重、聚集权重和惯性权重,提高收敛速度和精度;引入差分算法,提高最后时刻收敛速度;最终选取 9个测试函数做仿真试验对比.结果表明,相较于基础蜻蜓算法、差分进化蜻蜓算法,基于混沌映射和差分进化改进后的蜻蜓算法收敛速度和精度提升显著,避免陷入局部最优解,能获得稳定可靠的全局最优解.

Abstract

An improved dragonfly algorithm based on chaotic mapping and differential evolution was proposed to address several issues encountered in the original algorithm.The initial population's significant randomness and the difficulty in adjusting algorithmic weight parameters led to low convergence accuracy.Additionally,later-stage population contraction restrictions resulted in decreased vitality and slow convergence speed.By employing Tent chaotic mapping,the population's initial distribution was made more uniform.The alignment,clustering,and inertia weights were adjusted to enhance convergence speed and accuracy.The introduction of the differential evolution algorithm aimed to accelerate convergence at the final stages.Finally,nine test functions were selected for comparative simulation experiments.The results demonstrated that,compared to the basic dragonfly algorithm and the differential evolution dragonfly algorithm,the improved dragonfly algorithm based on chaotic mapping and differential evolution has significantly improved convergence speed and accuracy,avoiding getting stuck in local optima and obtaining stable and reliable global optimal solutions.
