| 中文摘要: |
| 混合蛙跳算法是一种新兴的启发式全局优化算法。本文研究了其寻优机制,提出了一种采用小生境技术的混合蛙跳算法:运用RCS小生境技术,使各子种群动态形成了互相独立的搜索空间;在解的更新公式中,设计了一种自适应因子来调节移动步长;采用种群淘汰机制,随机初始化已陷入局部最优的子种群。实验结果表明:本文给出的算法有效提高了寻优精度和收敛速度。 |
| 英文摘要: |
| Shuffled frog leaping algorithm (SFLA) is a new heuristic global optimization algorithm.After studying the optimization mechanism of SFLA,this paper proposes a shuffled frog leaping algorithm using niche technology.The new algorithm applies the RCS niche technology to make each sub-population dynamically form search spaces independent of one another.In the update formula for the solution,an adaptive factor is designed to adjust the moving step.Furthermore,the population elimination mechanism is used in the algorithm,to randomly initialize the sub-population which falls into the local optimum.Experimental results show that the algorithm in this paper improves the optimization accuracy and convergence speed effectively. |
