In Chile, due to the explosive increase of new Coronavirus disease 2019 (COVID-19) cases during the first part of 2021, the ability of health services to accommodate new incoming cases was jeopardized. It has become necessary to be able to ...
Dynamic string-averaging CQ-methods for the split feasibility problem with percentage violation constraints arising in radiation therapy treatment planning [0.03%]
求解放射治疗计划中带有违反约束百分比的分裂可行性问题的动力字符串平均CQ方法
Mark Brooke,Yair Censor,Aviv Gibali
Mark Brooke
We study a feasibility-seeking problem with percentage violation constraints (PVCs). These are additional constraints that are appended to an existing family of constraints, which single out certain subsets of the existing constraints and d...
Managing bank performance under COVID-19: A novel inverse DEA efficiency approach [0.03%]

The evolution of the COVID-19 pandemic is highly unpredictable; however, its impacts are limited to neither a single sector nor a single country. This study evaluates the performance and efficiency of 49 Islamic banks across 10 countries du...
On the optimal layout of a dining room in the era of COVID-19 using mathematical optimization [0.03%]
基于数学优化的新冠肺炎疫情下的餐厅就餐座位最优布局研究
Claudio Contardo,Luciano Costa
Claudio Contardo
We consider the problem of maximizing the number of people that a dining room can accommodate provided that the chairs belonging to different tables are socially distant. We introduce an optimization model that incorporates several characte...
Modeling of Covid-19 trade measures on essential products: a multiproduct, multicountry spatial price equilibrium framework [0.03%]
新冠疫情下医药产品贸易模型——多产品、多国家空间价格均衡框架

This paper presents an applied study of scheduling buses and drivers for the Beijing Bus Group (BJBUS), the largest bus company in China. This is pioneering research in China for bus transit scheduling using computers based on a unified mod...
Perturbation-resilient block-iterative projection methods with application to image reconstruction from projections [0.03%]
具有抵抗扰动的块迭代投影方法及其在从投影重建图像中的应用
R Davidi,G T Herman,Y Censor
R Davidi
A block-iterative projection algorithm for solving the consistent convex feasibility problem in a finite-dimensional Euclidean space that is resilient to bounded and summable perturbations (in the sense that convergence to a feasible point ...

Yair Censor
We study the common fixed point problem for the class of directed operators. This class is important because many commonly used nonlinear operators in convex optimization belong to it. We propose a definition of sparseness of a family of op...
