The second derivative of an envelope cannot be expressed only by second derivatives of the constituent functions. By taking account of this fact, we derive new second order necessary optimality conditions for minimization of a sup-type function. The conditions involve an extra term besides the second derivative of the Lagrange function. Furthermore, we will comment on the relationship between the extra term and a kind of second order directional derivative of the sup-type function. 相似文献

本文考虑一类均衡约束为二阶锥约束广义方程的数学规划问题.
我们通过一个非光滑映射的方向导数, 给出了临界锥的定义,
并建立它在可行点处的等价形式. 基于此临界锥,
我们提出了均衡约束为二阶锥约束广义方程的数学规划问题的二阶充分性条件,
并且验证了在适当的条件下, M-稳定点处的二阶充分性条件是二阶增长条件成立的充分条件. 相似文献

本文讨论一类具非线性二阶导数项的Schrodinger方程,它在物理上描述了上混合振荡传播.根据基态的变分特征,运用势井方法和凹方法,我们获得了其初值问题整体解存在的一个最佳条件,另外还证明了当初值多小时,初值问题的整体解存在. 相似文献

A group of curves generates a new curve which is called an envelope. When one deals with a minimization problem with infinitely many inequality constraints, one must encounter an envelopelike effect caused by the constraints. In this paper we present second-order necessary conditions, which involve a new term besides the second derivative of the Lagrange function.We apply our results to minimizing problems of sup-type functions. One will observe in examples that the new term given in this paper explains well the behavior of the second directional derivative of the sup-type function. 相似文献

1. IntroductionThe LCI optimization problems exist extensively in various optimization problems.FOr example, the problems from nonlinear complementarity) variational inequality andCd nonlinear programming can be formed as LCI optimization problems. In addition,LCI optimization problems also arise from the extended linear-quadratic programmingproblems, nonlinear minimax problems, stochastic optimization problems and somesemi-infinite programs.

In this paper we establish necessary and sufficient second order optimality conditions for theL
1-problem. The approach is based on optimality criteria in terms of a curved second directional derivative, discussed in [3]. Our conditions generalize conditions for theL
1-problem given in [6]. An example demonstrates the usefulness of our criteria.This research was supported by NSF Grant No. ECS-8214081 and the Fund for Promotion of Research at the Technion, andDeutsche Forschungsgemeinschaft. 相似文献
