基于化学模拟的鲁棒粒子群优化算法

Robust Particle Swarm Optimizer based on Chemomimicry

Casey Kneale, Karl S. Booksh

摘要:

提出了一种松散地基于结晶现象和混沌因子的粒子群优化算法。该方法具有三个阶段:扩散,定向运动,和成核。在扩散阶段,无规行走是粒子运动的唯一贡献者。随着算法的进展,混沌的贡献减少,并向全局最佳位置移动,直到收敛。该算法被发现是更强大的局部极小值的多峰测试功能比标准的粒子群算法,是专为问题的功能实验精度。

英文摘要:

A particle swarm optimizer (PSO) loosely based on the phenomena of crystallization and a chaos factor which follows the complimentary error function is described. The method features three phases: diffusion, directed motion, and nucleation. During the diffusion phase random walk is the only contributor to particle motion. As the algorithm progresses the contribution from chaos decreases and movement toward global best locations is pursued until convergence has occurred. The algorithm was found to be more robust to local minima in multimodal test functions than a standard PSO algorithm and is designed for problems which feature experimental precision.
