Simulation results indicate that the convergence of pattern search algorithm is nine times as fast as the hill-climbing method; it converges to the maximum coupling efficiency within 20 iterations for the five degrees of freedom alignment between the laser diode and the single mode fiber. 仿真结果表明,激光二极管与单模光纤五自由度对准时,模式搜索法只需20次迭代就可以找到最大点,收敛速度是爬山法的9倍。
The algorithm of the specific implementation is as follows: A maximum number of iterations is set, before entering some iteration, the advanced algorithm compares the number of this iteration with the maximum value. 该算法的主要思想是:设置一个最大的迭代次数,每一次进入迭代之前,将本次迭代的次数与最大值比较。
Effects of population size, initial inertia weight, acceleration constants, maximum particle velocity and maximum number of iterations on PSO are studied in detail. 详细研究了群体规模、惯性权重、加速常数、最大速度和最大代数对微粒群算法的影响。
