【期刊论文】Visualization and Genetic Algorithms in Minimax Theory for Nonlinear Functionals
刘希玉, Xiyu Liu, John Frazer, and Ming Xi Tang
,-0001,():
-1年11月30日
In this paper, evolution and visualization of the existence of saddle points of nonlinear functionals or multi-variable functions in finite dimensional spaces are presented. New algorithms are developed based on the mountain pass lemma and link thery in nonlinear analysis. Further more, a simple comparison of the steepest descent algorithm and the genetic algorithm is given. The process of the saddle point finding is visualised in an inteactive graphical interface.

【期刊论文】Design Optimization by Functional Neural Networks
刘希玉, Liu Xiyu, Duan Huichuan, Tang Mingxi
,-0001,():
-1年11月30日
This paper presents a new design optimization technique by artificial neural networks. Based on the theory of partial ordering and cones in Banach spaces, a new kind of neural networks with functional links is proposed. Learning algorithm lies heavily on the ordering structure of the sample space with an alternative feed-forward and backpropagation technique. Experiments are described with comparison with traditional functional link networks and wavelet networks.

【期刊论文】WEEK SOLUTIONS OF SINGULAR ELLIPTIC BOUNDARY VALUE PROBLEMS
刘希玉, Liu Xiyu, Qu Jianhua

In this paper, we give some new results on the existence and properties of solutions of singular elliptic boundary value problems of second order. We discuss the difference of weak solutions and classical solutions.
