The heuristic analysis, some concepts and theorems of constrained optimization are employed, e. g., linear feasible direction ( lfd ), and then the proof is first provided for the uniqueness, i. e., maximum nongaussianity is the sufficient and necessary condition to independent source recovery. moreover, based on the conclusion of the uniqueness of maximum nongaussianity, the paper also proposes an alternative but straightforward approach to the proof for the well known “ one - bit - matching ” conjecture presented in multi - unit approaches
和基於啟發性分析等傳統方法和結論比較，文中引入了線性化可行方向（ linearfeasibledirection ， lfd ）等約束優化概念和理論，首次給出了基於峭度的最大非高斯估計的唯一性證明，指出最大非高斯估計是獨立源提取的充分和必要條件。 -
The second chapter reveals the mathematical essence of entropy regularization method for the finite min - max problem, through exploring the relationship between entropy regularization method and exponential penalty function method. the third chapter extends maximum entropy method to a general inequality constrained optimization problem and establishes the lagrangian regularization approach. the fourth chapter presents a unified framework for constructing penalty functions by virtue of the lagrangian regularization approach, and illustrates it by some specific penalty and barrier function examples
第一章為緒論，簡單描述了熵正則化方法與罰函數法的研究現狀；第二章，針對有限極大極小問題，通過研究熵正則化方法與指數（乘子）罰函數方法之間的關系，揭示熵正則方法的數學本質；第三章將極大熵方法推廣到一般不等式約束優化問題上，建立了拉格朗日正則化方法；第四章利用第三章建立的拉格朗日正則化方法，給出一種構造罰函數的統一框架，並通過具體的罰和障礙函數例子加以說明。 -
Secondly, a non - linear mapping function from multiple inputs ( design variables ) to output ( maximum dynamic stress ) is constructed within bp neural networks, in order to obtain the constraint function values that are necessary in optimum design of structures using genetic algorithms and get the optimum solutions. the generation ability of the bp network after training can be used to replace the calculation of fem, which makes the constrained optimization to be possible
其次，由於動應力的有限元法計算過程復雜，計算量巨大，在應用優化演算法時，需要反復計算，為了使優化過程可行，設計了bp神經網路，利用有限元計算的樣本數據建立起結構設計參數（輸入）與動應力（輸出）的非線性映射關系，從而代替有限元法，快速計算結構動應力。 -
Taking all the interval number s in the equations as optimal design variables and representing the lower and th e upper bounds of each interval number as the boundary constrain of the variable respectively, the maximum and the minimum of various components of the solution are achieved by using the constrained optimization method
將方程組中的所有區間數都作為設計變量，區間量的變化區間作為相應的設計變量的邊界約束，運用約束優化法求出方程組解的各元素的最大值和最小值。
