非线性半定规划的弱非退化概念

Weak notions of nondegeneracy in nonlinear semidefinite programming

Roberto Andreani, Gabriel Haeser, Leonardo M. Mito, Héctor Ramírez

摘要:

约束非退化条件是非线性半定规划中最重要和最有用的约束规格之一。它的特点是在任何固定的规范正交基,让我们说,$\ell$维内核的约束矩阵,由线性独立的一组$\ell(\ell+1)/2$衍生向量。我们表明,这种线性独立的要求,可以等价地制定在一个较小的集合,$\ell$衍生向量,考虑所有的规范正交基的内核。这使我们能够确定,并不是所有的基地是相关的一个约束规格被定义,从而产生一个严格的较弱的变种nondegeneracy相关的整体收敛的外部惩罚方法。我们使用其中的一些想法,重新审视的方法Forsgren [数学。88,105- 128,2000]用于利用约束的变换的稀疏结构来定义约束规格,这使我们使用更简单的变换来开发非简并性的另一个放松的概念。如果考虑约束函数在给定点处的导数的零点,而不是函数本身在该点的邻域中的零点,则我们得到连接Forsgren条件和我们的条件的更弱的约束规格。

英文摘要:

The constraint nondegeneracy condition is one of the most relevant and useful constraint qualifications in nonlinear semidefinite programming. It can be characterized in terms of any fixed orthonormal basis of the, let us say, $\ell$-dimensional kernel of the constraint matrix, by the linear independence of a set of $\ell(\ell+1)/2$ derivative vectors. We show that this linear independence requirement can be equivalently formulated in a smaller set, of $\ell$ derivative vectors, by considering all orthonormal bases of the kernel instead. This allows us to identify that not all bases are relevant for a constraint qualification to be defined, giving rise to a strictly weaker variant of nondegeneracy related to the global convergence of an external penalty method. We use some of these ideas to revisit an approach of Forsgren [Math. Prog. 88, 105--128, 2000] for exploiting the sparsity structure of a transformation of the constraints to define a constraint qualification, which led us to develop another relaxed notion of nondegeneracy using a simpler transformation. If the zeros of the derivatives of the constraint function at a given point are considered, instead of the zeros of the function itself in a neighborhood of that point, we obtain an even weaker constraint qualification that connects Forsgren's condition and ours.
