This proposal concerns the investigation, analysis and implementation of numerical solution methods for a family of linear systems that arise from problems that can be generally posed as minimization problems with constraints. Such problems are extremely important, and they frequently appear in a surprisingly large scope of scientific models. Examples of relevant applications include computer graphics, data mining, image processing, medical imaging, fluid flow, electromagnetics, and many more instances.

这个建议涉及的调查，分析和实施的数值求解方法的一个家庭的线性系统所产生的问题，一般可以构成为最小化问题的约束。这类问题极其重要，而且它们经常出现在范围大得惊人的科学模型中。相关应用的示例包括计算机图形学、数据挖掘、图像处理、医学成像、流体流动、电磁学以及更多实例。
