	6	On the local convergence of a stochastic semismooth Newton method for nonsmooth nonconvex optimization显示文摘In this work,we present probabilistic local convergence results for a stochastic semismooth Newton method for a class of stochastic composite optimization problems involving the sum of smooth nonconvex and nonsmooth convex terms in the objective function.We assume that the gradient and Hessian information of the smooth part of the objective function can only be approximated and accessed via calling stochastic firstand second-order oracles.The approach combines stochastic semismooth Newton steps,stochastic proximal gradient steps and a globalization strategy based on growth conditions.We present tail bounds and matrix concentration inequalities for the stochastic oracles that can be utilized to control the approximation errors via appropriately adjusting or increasing the sampling rates.Under standard local assumptions,we prove that the proposed algorithm locally turns into a pure stochastic semismooth Newton method and converges r-linearly or r-superlinearly with high probability.

	7	A MULTIGRID SEMISMOOTH NEWTON METHOD FOR SEMILINEAR CONTACT PROBLEMS显示文摘这份报纸在被激发由并且包括 Signorini 的问题打的线性有弹性的接触的函数空格为抑制不平等的优化问题的一个类开发并且分析 multigrid semismooth 牛顿方法。在问题 superlinear 本地人集中的合适的 Moreau-Yosida 类型规则化为 semismooth 牛顿方法的一个班被获得以后,我们显示出那。另外,为规则化介绍的错误的顺序的估计被导出。纸的主要部分为 semismooth 牛顿系统被奉献给 multilevel preconditioner 的分析。我们为关于足够地小的规则化参数和格子层次的数字柔韧的 multigrid 周期的收缩率证明严密界限。而且,它适用于适应地精制的格子。纸与数字结果得出结论。	Michael Ulbrich Stefan Ulbrich Daniela Bratzke	2017	Journal of Computational Mathematics2017，35，4：	0
