基于混沌自适应遗传算法的非晶合金干式变压器优化设计

Gaoya dianqi, 2022
针对目前变压器优化设计周期长、效率低与制造成本高等问题，采用了一种改进的遗传算法（IGA,improved genetic algorithm）—混沌自适应遗传算法（CAGA,chaotic adaptive genetic algorithm）对变压器的参数进行优化。该算法结合了混沌遗传算法（CGA,chaos genetic algorithm）与自适应遗传算法（AGA,adaptive genetic algorithm）各自的优点，将混沌序列、自适应遗传算子与精英策略引入传统遗传算法（SGA ...

降低DCO-OFDM系统峰均功率比的IGA-SLM算法

Guangtongxin yanjiu, 2020
针对可见光通信中直流偏置光-正交频分复用（DCO-OFDM）系统存在的高峰均功率比（PAPR）问题,可采用选择性映射算法来降低系统的PAPR。由于选择性映射算法只能在有限组相位旋转序列里选择局部最优,因此引入遗传算法来搜索全局最优解,同时针对遗传算法容易产生过早收敛的问题,文章提出自适应调整机制、自适应多点交叉机制、最优解保护机制和立即淘汰机制来改进遗传算法,进而提出改进型遗传选择性映射算法（IGA-SLM）。仿真结果表明,该算法可显著降低可见光通信DCO-OFDM系统的PAPR。
