改进粒子群优化算法及其在4G 网络基站选址中的应用
Improved Particle Swarm Optimization and Its Application in 4G Network Base Station Location
摘要
Abstract
Since the PSO search accuracy is not high and its easy falling into the disadvantage of local minimum as a whole , this article proposes an improved particle swarm optimization algorithm .On the one hand the updated velocity formula using the weighted value of individual extreme of particles in particle swarm replaces the individual extreme of particles in this algorithm .On the other hand this improvement effectively enhances the convergence speed and optimal global searching ability of the particle swarm opti -mization by adjusting the inertia weight of two non-linear decreasing function .Then , the researchers veri-fy the global convergence and optimal searching ability of the improved algorithm by simulating the four reference functions.Finally, the improved algorithm is applied to the optimized location of a 4G network base station in a city of the Pearl River Delta region .The results and applications demonstrate that the im-proved particle swarm optimization possesses greater optimized convergence speed and global searching a -bility.关键词
