摘要
小波混沌神经网络已经成功地解决了函数优化和组合优化问题。研究了分段指数退火函数的Morlet小波混沌神经元模型,给出了分段小波混沌神经元的倒分岔图和Lyapunov指数图。在小波混沌神经网络的基础上,加入了分段指数退火函数,提出了一种新的改进的小波混沌神经网络,并把它应用到函数优化和组合优化问题中。仿真结果表明,改善了小波混沌神经网络的寻优能力,改进的小波混沌神经网络优于原来的小波混沌神经网络。
Wavelet chaotic neural networks have successfully solved function and combinatorial optimization problems.Morlet wavelet chaotic neural units with the annealing function of subparagraph index are studied.The reversed bifurcation and Lyapunov exponent figures are respectively given.On the basis of wavelet chaotic neural network,the annealing function of subparagraph index is introduced into network,a new reformative wavelet chaotic neural network is presented.Then it is applied to function and combinatorial optimization problems.The simulation results show that the search-optimization capacity of wavelet chaotic neural network has been improved and the reformative wavelet chaotic neural network is superior to the primary wavelet chaotic neural networks.
