A boosted dc algorithm for non-differentiable dc components with non-monotone line search
收藏 引用
COMPUTATIONAL OPTIMIZATION AND APPLICATIONS 2024年 第3期88卷 783-818页
作者: Ferreira, O. P. Santos, E. M. Souza, J. C. O. Univ Fed Goias Inst Matemat & Estat BR-74001970 Goiania GO Brazil Inst Fed Educ Ciencia & Tecnol Maranhao IFMA BR-65930000 Acailandia MA Brazil Aix Marseille Univ AMSE CNRS Marseille France Univ Fed Piaui Dept Math UFPI Teresina PI Brazil
We introduce a new approach to apply the boosted difference of convex functions algorithm (BdcA) for solving non-convex and non-differentiable problems involving difference of two convex functions (dc functions). Supp... 详细信息

MATHEMATICAL PROGRAMMING 2018年 第1期169卷 95-118页
作者: Aragon Artacho, Francisco J. Fleming, Ronan M. T. Vuong, Phan T. Univ Alicante Dept Math Alicante Spain Univ Luxembourg Luxembourg Ctr Syst Biomed Syst Biochem Grp Campus Belval L-4362 Esch Sur Alzette Luxembourg
We introduce two new algorithms to minimise smooth difference of convex (dc) functions that accelerate the convergence of the classical dc algorithm (dcA). We prove that the point computed by dcA can be used to define... 详细信息

OPTIMIZATION LETTERS 2023年 第1期17卷 75-87页
作者: Zuo, Xinyi Jiang, Yi Sichuan Normal Univ Sch Math Sci Visual Comp & Virtual Real Key Lab Chengdu 610066 Sichuan Peoples R China
In this paper, an NP-hard problem of minimizing a sum of pointwise minima of two functions is considered. Using a new equivalent formula, we propose a smooth approximation and an ADMM algorithm for solving the problem... 详细信息
