| 摘 要： | 首先对一类集合,从两个不同的侧面刻画了集合沿某个方向的极小极大问题,并阐述了极小值与极大值相等的条件.对应于经典的优化问题,借助于目标函数的上图,将原问题与对偶问题对应于某个集合的极小极大问题,得到强对偶定理.最后,对Hilbert空间上的一类约束优化问题进行了刻画,得到了这一类约束优化问题的强对偶定理,进而可以通过对偶问题求解原问题.

| Abstract: | For a nonempty subset in Rn+1,two simple optimization problems are firstly constructed from the necessary and sufficient conditions for the attainments and equality of the optimal values in Duality Theorems.These problems will be used as an analytical framework for constrained optimization duality.Corresponding to the classical optimization problem,by means of the epigraph of the objective function,the original problem and its dual problem as the minimax problems of a set,the strong duality theorem is obtai... |
