摘    要:本文针对混合蛙跳算法(shuffled frog leaping algorithm,SFLA)早熟收敛的问题,将云模型算法融合于SFLA算法中,形成一种云变异蛙跳算法(normal cloud mutation SFLA,NCM-SFLA),弥补混合蛙跳算法后期容易陷入局部最优的不足.同时利用算法易于并行的特点,在多核环境下基于.NET4的并行拓展库(parallel extensions)进行算法的并行优化.将其应用于梯级水库优化调度中,实例计算表明,与多维动态规划算法(MDP)相比,NCM-SFLA方法具有更好的全局寻优能力和较快的收敛速度,在现有的计算条件下该并行算法能有效缩短程序运行时间,求解梯级水库优化调度问题是合理、有效的.

关 键 词:云变异蛙跳算法  多核  并行  梯级水库  优化调度

Abstract:To improve the premature convergence problem of traditional shuffled frog leaping algorithm (SFLA), in this paper, cloud model algorithm mix together with SFLA algorithm, then a normal cloud mutation shuffled frog leaping algorithm (normal cloud mutation SFLA, NCM-SFLA) is proposed, which is to make up the shortage of shuffled frog leaping algorithm that is easy to fall into local optimal solution. At the same time, the algorithm is easy to be parallel, parallel extensions are used to parallel optimization of algorithm in multi core environment. Then the algorithms are applied to cascade reservoirs optimal operation. The test case of practical application shows that, compared with the multidimensional dynamic programming algorithm (MDP), NCM-SFLA has better global search ability and fast convergence speed, and the parallel algorithm can effectively shorten the running time of program in the calculation of existing conditions. Moreover, to solve the cascade reservoirs optimal operation is reasonable, effective by using the new algorithms.
Keywords:normal cloud mutation shuffled frog leaping algorithm  multi core  parallel optimization  cascade reservoirs  optimal operation
