Abstract(in English) In this paper, we propose a new hierarchical genetic algorithm (HGA) adopting variability of individuals and fireworks algorithm (FA). The proposed method has higher and lower layers. In the higher layer, the proposed method realizes the global rough search inspired FA. In the lower layer, the proposed method realizes the local detailed search based on GA adopting variability of individuals. Furthermore, the proposed method is applied to design of a switching median filter (SMF) with signal dependent multi-thresholds. In the method, the proposed HGA tunes an optimal combination of two kinds of thresholds. One is switching thresholds to detect a noise, and the other is selecting thresholds to choose a suitable switching threshold. As a suitable selecting threshold, the variance of signals is used. The validity and effectiveness of the proposed method are verified by the experiments.
