An Enhanced Particle Swarm Optimization Algorithm for Design Problem
摘要
In this work, particle swarm optimization (PSO) algorithm is improved, called EnPSO, for design truss system. First, a factor is added into PSO to create two phases (local and global search). A distribution function using Lévy flights is employed to exploit the narrow search space. The results obtained from investigations of EnPSO algorithm are compared with several well-known candidates and original. Finally, a structure with multi-loading consisting of two constraints is designed to validate the accuracy of this method.
