Convergent nested Alternating Minimization algorithms for Nonconvex Optimization Problems
收藏 引用
MATHEMATICS OF OPERATIONS RESEARCH 2023年 第1期48卷 53-77页
作者: Gur, Eyal Sabach, Shoham Shtern, Shimrit Technion Israel Inst Technol Fac Ind Engn & Management IL-3200003 Haifa Israel
We introduce a new algorithmic framework for solving nonconvex optimization problems, that is called nested alternating minimization, which aims at combining the classical alternating minimization technique with inner... 详细信息

nested Alternating Minimization with FISTA for Non-convex and Non-smooth Optimization Problems
收藏 引用
JOURNAL OF OPTIMIZATION THEORY AND APPLICATIONS 2023年 第3期199卷 1130-1157页
作者: Gur, Eyal Sabach, Shoham Shtern, Shimrit Technion Israel Inst Technol Fac Data & Decis Sci IL-320003 Hefa Israel
Motivated by a recent framework for proving global convergence to critical points of nested alternating minimization algorithms, which was proposed for the case of smooth subproblems, we first show here that non-smoot... 详细信息

Inexact first-order primal-dual algorithms
收藏 引用
COMPUTATIONAL OPTIMIZATION AND APPLICATIONS 2020年 第2期76卷 381-430页
作者: Rasch, Julian Chambolle, Antonin Westfalische Wilhelms Univ WWU Munster Appl Math Munster Inst Anal & Computat Math Munster Germany CNRS Ecole Polytech CMAP Paris France
We investigate the convergence of a recently popular class of first-order primal-dual algorithms for saddle point problems under the presence of errors in the proximal maps and gradients. We study several types of err... 详细信息

Force-gradient nested multirate methods for Hamiltonian systems
收藏 引用
COMPUTER PHYSICS COMMUNICATIONS 2015年 187卷 91-97页
作者: Shcherbakov, Dmitry Ehrhardt, Matthias Guenther, Michael Peardon, Michael Berg Univ Wuppertal Lehrstuhl Angew Math & Numer Anal D-42119 Wuppertal Germany Trinity Coll Dublin Sch Math Dublin 2 Ireland
Force-gradient decomposition methods are used to improve the energy preservation of symplectic schemes applied to Hamiltonian systems. If the potential is composed of different parts with strongly varying dynamics, th... 详细信息

Swapping the nested fixed point algorithm: A class of estimators for discrete Markov decision models
收藏 引用
ECONOMETRICA 2002年 第4期70卷 1519-1543页
作者: Aguirregabiria, V Mira, P Boston University MA U.S.A.vaguirre@bu.edu CEMFI Casado del Alisal Madrid Spainmira@cemfi.es
This paper proposes a new nested algorithm (NPL) for the estimation of a class of discrete Markov decision models and studies its statistical and computational properties. Our method is based on a representation of th... 详细信息
