摘　　要：在对Log istic映射轨道概率密度深入分析的基础上,提出了基于幂函数载波的混沌优化方法,分析了幂函数载波对混沌轨道概率密度、遍历性的影响.复杂函数优化的仿真结果表明,幂函数载波方式能更为有效地发挥混沌优化的全局和局部搜索能力,证实了幂函数载波混沌优化方法的有效性.Based on the analysis of the probability density of the unstable orbits imbedded in the logistic attractor, an optimization method using power function carrier is proposed, which greatly improves the probability density and the ergodic property of the chaotic orbit. The simulation results of complex function optimization show the effectiveness of the method in function optimization , and imply that the method can enhance the global and local searching ability of the chaotic optimization.
