摘要
粒子群优化算法是一种基于群体的自适应搜索优化算法,存在后期收敛慢、搜索精度低、容易陷入局部极小等缺点,为此提出了一种改进的粒子群优化算法,从初始解和搜索精度两个方面进行了改进,提高了算法的计算精度,改善了算法收敛性,很大程度上避免了算法陷入局部极小.对经典函数测试计算,验证了算法的有效性.
Particle Swarm Optimization Algorithm is a kind of auto-adapted search optimization based on community. But the standard particle swarm optimization is used resulting in slow after convergence, low search precision and easily leading to local minimum. A new Particle Swarm Optimization algorithm is proposed to improve from the initial solution and the search precision. The obtained results showed the algorithm computation precision and the astringency are improved, and local minimum is avoided, The experimental results of classic functions show that the improved PSO is efficient and feasible.
