Pattern search algorithm using chaos and its application. (Chinese. English summary) Zbl 1150.68455

Summary: A new pattern search algorithm using chaos, in which the ergodicity of chaos is applied to produce stochastic move direction and length in exploratory move, was proposed. Moreover, two-staged pattern move was employed for different search phases. The global search property of chaotic optimization was utilized in the proposed algorithm and it could realize global optimum, and two-staged pattern move had fast convergence velocity. The training of fuzzy neural networks was implemented by using the proposed optimization algorithm, and simulation results have demonstrated that it has efficient search ability.
