So it is good at searching for the best and is easy to be programmed. It is raised formally by Eusuff and Lansey in 2003 and become gradually popular the field of academic and optimization in recent years Firstly, this paper describes the theoretical basis of shuffled frog leaping algorithm - Particle Swarm Optimization and their relationship. Then summarize the basic principle and flow of shuffled frog leaping. Next we solve problems about the application on packing bags.?Based on the above study, we raise two new shuffled frog leaping algorithm: an improved shuffled frog leaping with a charge on it and a new shuffled frog leaping algorithm based on worst disturbance. The simulations and analysis about the new algorithms are done by experiment. The subject provides a certain reference value for the further study and improvement of shuffled frog leaping algorithm Key Words: Shuffled Leaping Frog Algorithm, Sub-heuristic Algorithm, Engineering Optimization, Knapsack problem, Particle Swarm Optimization, Worst Disturbance 目 录 TOC \o 1-3 \h \u HYPERLINK \l _Toc7881 第一章 绪 论 PAGEREF _To
