摘要： 针对量子遗传算法存在的易陷入局部极小等问题，提出一种模糊量子遗传算法。该算法采用一种变尺度混沌优化方法，只需设 2个循环，内循环进行混沌搜索，外循环负责缩小区间，通过改进它的收敛策略，可以避免混沌优化在区间内的盲目重复搜索。利用改进的变尺度混沌优化方法，对量子遗传操作产生的种群进行混沌搜索寻优，同时模糊控制更新，加快种群的进化。仿真结果表明，该方法的寻优效果优于量子遗传算法及遗传算法。

Abstract: Aiming at the problem of Quantum Genetic Algorithm(QGA) exists easily getting into local minimum. this paper presents a fuzzy QGA. It adopts a mutative scale chaos optimization method. The method has nested iterations, the inner is used for chaos search and the outer is used to reduce the range. The blind repeated search of chaos optimization in search space can be avoided through ameliorating its constringency strategy. Chaotic search for the optimization using this chaos optimization method is implemented towards the population produced by the quantum genetic algorithm, and fuzzy control is updated the population in order to speed the evolution of the population. Simulation results show that this algorithm is more effective than QGA and genetic algorithm.

Key words: Quantum Genetic Algorithm(QGA), chaos optimization, constringency strategy, mutative scale, fuzzy control
