Variable smoothing incremental aggregated gradient method for nonsmooth nonconvex regularized optimization

期刊: OPTIMIZATION LETTERS, 2021; 15 (6)

In this paper, we focus on the problem of minimizing the sum of nonconvex smooth component functions and a nonsmooth weakly convex function composed w......

Study on proportionate flowshop scheduling with due-date assignment and position-dependent weights

期刊: OPTIMIZATION LETTERS, 2021; 15 (6)

In a recent paper, Jiang et al. (EngOptim 52(1):37-52, 2020) considered proportionate flowshop scheduling with position-dependent weights. For common ......

Approximation algorithms for the multiprocessor scheduling with submodular penalties

期刊: OPTIMIZATION LETTERS, ; ()

In this paper, we consider multiprocessor scheduling with submodular penalties to extend multiprocessor scheduling with rejection to submodular functi......

A covering traveling salesman problem with profit in the last mile delivery

期刊: OPTIMIZATION LETTERS, ; ()

This paper introduces and formulates a covering traveling salesman problem with profit arose in the last mile delivery. In this problem, a set of vert......

An approximation algorithm for the k-generalized Steiner forest problem

期刊: OPTIMIZATION LETTERS, ; ()

In this paper, we introduce the k-generalized Steiner forest (k-GSF) problem, which is a natural generalization of the k-Steiner forest problem and th......

Explicit extragradient-like method with adaptive stepsizes for pseudomonotone variational inequalities

期刊: OPTIMIZATION LETTERS, ; ()

The purpose of this paper is to introduce a new modified subgradient extragradient method for finding an element in the set of solutions of the variat......

A variable neighborhood search for the last-mile delivery problem during major infectious disease outbreak

期刊: OPTIMIZATION LETTERS, ; ()

During major infectious disease outbreak, such as COVID-19, the goods and parcels supply and distribution for the isolated personnel has become a key ......

Maximum shortest path interdiction problem by upgrading edges on trees under hamming distance

期刊: OPTIMIZATION LETTERS, ; ()

We consider the maximum shortest path interdiction problem by upgrading edges on trees under Hamming distance (denoted by (MSPITH)), which has wide ap......

A difference-of-convex programming approach with parallel branch-and-bound for sentence compression via a hybrid extractive model

期刊: OPTIMIZATION LETTERS, ; ()

Sentence compression is an important problem in natural language processing with wide applications in text summarization, search engine and human-AI i......

Bounds of the solution set of the tensor complementarity problem

期刊: OPTIMIZATION LETTERS, ; ()

Recently, the estimation problem of upper and lower bounds of the solution set of the tensor complementarity problem has been studied when the tensor ......

An approximation algorithm for the k-level facility location problem with outliers

期刊: OPTIMIZATION LETTERS, ; ()

In this paper, we study the k-level facility location problem with outliers (k-LFLPWO), which is an extension of the well-known k-level facility locat......

Relating l(p) regularization and reweighted l(1) regularization

期刊: OPTIMIZATION LETTERS, ; ()

We propose a general framework of iteratively reweighted l(1) algorithms for solving l(p) regularization problems. We show that all the limit points o......

An adaptive agent-based process model for optimizing innovative design

期刊: OPTIMIZATION LETTERS, 2021; 15 (2)

The purpose of this paper is to dynamically optimize the process architecture of innovative design. We introduce an adaptive agent-based process model......

Event-based optimization approach for solving stochastic decision problems with probabilistic constraint

期刊: OPTIMIZATION LETTERS, 2021; 15 (2)
