摘要: A hybrid genetic algorithm (GA) based on the clustering fitness sharing and elite replacement is proposed. Our proposed GA can effectively solve multimodal optimization in distributed multipump Raman amplifier (DMRA). The optimal results show that, under conditions of ON-OFF gain > 10 dB, relative flatness 100 nm be designed from DMRA with five pumps after our GA. There are four schemes to realize required setup parameters simulation.
