ABSTRACT

In this paper, we first extend the diminishing stepsize method for nonconvex constrained problems presented in F. Facchinei, V. Kungurtsev, L. Lampariello and G. Scutari [Ghost penalties in nonconvex constrained optimization: Diminishing stepsizes and iteration complexity, To appear on Math. Oper. Res. 2020. Available at https://arxiv.org/abs/1709.03384.] to deal with equality constraints and a nonsmooth objective function of composite type. We then consider the particular case in which the constraints are convex and satisfy a standard constraint qualification and show that in this setting the algorithm can be considerably simplified, reducing the computational burden of each iteration.

通过幻影罚分逐步减小非凸复合问题的方法:从一般到凸正则约束情况

摘要

在本文中,我们首先针对F. Facchinei,V。Kungurtsev,L.Lampariello和G. Scutari [非凸约束优化中的幽灵罚分:递减步长和迭代复杂度,在数学上出现。歌剧 Res。2020年。可在https://arxiv.org/abs/1709.03384。]处理等式约束和复合类型的不平滑目标函数。然后,我们考虑约束为凸且满足标准约束条件的特殊情况,并表明在这种设置下,可以大大简化算法,从而减少每次迭代的计算负担。
