This is an important project which requests time on the Cornell supercomputer to study the relative computational efficiencies of parallel and serial processors in solving very large economic optimization problems. The supercomputer is becoming a very important research tool in economic analysis. Many economic models which are realistic from a behavioral standpoint are not computationally tractable on standard mainframe computers. They are, however, solvable with the aid of a supercomputer. This project develops efficient vector algorithms for the solution of large economic optimization models. Technically, the research models large-scale equilibrium economies as variational inequality problems. This general set of problems encompasses a wide variety of economic frameworks, such as oligopolistic markets, inventory and investment optimization for firms, allocation and management of non-renewable resources, and traffic networks. Professor Nagurney is an experienced researcher in the areas of mathematical programming and economic optimization.

这是一个重要的项目，需要康奈尔超级计算机的时间来研究并行和串行处理器在解决非常大的经济优化问题时的相对计算效率。超级计算机正在成为经济分析中一个非常重要的研究工具。从行为的角度来看，许多经济模型是现实的，但在标准的大型计算机上无法进行计算处理。然而，在超级计算机的帮助下，它们是可以解决的。本项目开发了求解大型经济优化模型的有效向量算法。从技术上讲，该研究将大规模均衡经济建模为变分不等式问题。这一系列问题包括各种各样的经济框架，如寡头垄断市场、企业库存和投资优化、不可再生资源的分配和管理以及交通网络。Nagurney教授是数学规划和经济优化领域的资深研究员。
