| 摘 要： | 针对一种新的启发式全局优化算法类电磁机制算法,提出了一类改进的类电磁机制算法,改进了算法中局部搜索方法,搜索得到的初始种群更适宜于进化;对力的计算方法做了改进,使算法收敛速度加快;改进了粒子的更新过程,使得算法在进化后期能更有效地收敛到全局最优解.实验表明,与原算法相比,新算法性能更好、应用范围更广泛.

| Abstract: | On the basis of the Electromagnetism-like Mechanism method(EM),a new population-based stochastic global optimization algorithm,an improved electromagnetism-like mechanism method(IEM) is proposed.The new algorithm improves the local search process,and by the methods the population is more apt to be evolved.In order to speed up the convergence rapidity,the method for the calculation of each point's total force vector is modified.Finally,the point's updating mode is improved,which may cause the algorithm conve... |
