摘要:

我们研究了由图诱导结构的非线性规划(NLP)的解灵敏度。这些NLP出现在动态优化、随机优化、包含偏微分方程的优化和网络优化等应用中。我们证明,对于给定的两个节点,一个节点的对偶解灵敏度对另一个节点的数据扰动的灵敏度随图上这两个节点之间的距离呈指数衰减。换句话说,随着远离扰动点,解灵敏度逐渐减小。该结果称为灵敏度的指数衰减,成立于强二阶充分条件和线性独立约束资格之下。我们还提出了衰减率保持一致有界的条件,这允许我们表征无限图子图上NLP的灵敏度行为。理论发展通过数值示例加以说明。

英文摘要:

We study solution sensitivity for nonlinear programs (NLPs) whose structures are induced by graphs. These NLPs arise in many applications such as dynamic optimization, stochastic optimization, optimization with partial differential equations, and network optimization. We show that for a given pair of nodes, the sensitivity of the primal-dual solution at one node against a data perturbation at the other node decays exponentially with respect to the distance between these two nodes on the graph. In other words, the solution sensitivity decays as one moves away from the perturbation point. This result, which we call exponential decay of sensitivity, holds under the strong second-order sufficiency condition and the linear independence constraint qualification. We also present conditions under which the decay rate remains uniformly bounded; this allows us to characterize the sensitivity behavior of NLPs defined over subgraphs of infinite graphs. The theoretical developments are illustrated with numerical examples.
