Sensitivity analysis of the maximal value function with applications in nonconvex minimax programs

L. Guo, J. J. Ye, J. Zhang

摘要:

在本文中,我们进行灵敏度分析的最大值函数,这是最优值函数的参数最大化问题。我们的目的是研究最大值函数的各种次微分。利用一些灵敏度分析技巧,我们详细地得到了最大值函数的Fréchet次微分、极限次微分和水平次微分的上估计.导出的上估计只依赖于所有解的并集,而不依赖于其凸包或解集中的一个解。最后,我们将所得结果应用于非凸极大极小问题的一些新的最优性必要条件最优性条件。在非凹凸条件下,我们的Wolfe对偶方法与一阶方法相比,其必要条件更尖锐,约束规格更弱。

英文摘要:

In this paper, we perform sensitivity analysis for the maximal value function which is the optimal value function for a parametric maximization problem. Our aim is to study various subdifferentials for the maximal value function. We obtain upper estimates of Fréchet, limiting, and horizon subdifferentials of the maximal value function by using some sensitivity analysis techniques sophisticatedly. The derived upper estimates depend only on the union of all solutions and not on its convex hull or only one solution from the solution set. Finally, we apply the derived results to develop some new necessary optimality conditions for nonconvex minimax problems. In the nonconvex-concave setting, our Wolfe duality approach compare favourably with the first order approach in that the necessary condition is sharper and the constraint qualification is weaker.
