This grant supports travel of US researchers to attend the workshop on "Mutilevel methods and Optimization" from April 29 to May 2, 2013, at the Weizmann Institute of Science in Rehovot, Israel. The planned talks and panel discussions will cover classical problems such as partial differential equations, together with modern tasks such as web search and data mining. Speakers and participants in the workshop come from a variety of disciplines, including physics, biology, chemistry, economics, environment and earth sciences, computer science and engineering. A special two-hour panel "Challenges in Multilevel Computation: where should we be directing our efforts and our graduate students?" is planned for the second day. Multilevel solution methods for simulation and optimization problems over very large number of variables is central and important to virtually all disciplines in the sciences and engineering. These methodologies are very powerful because they exploit the fact that most computational problems have multiple scales. This notion of multiple scales may take on many different guises, including time and space, pixels, particles, proteins, or web-pages. This multiplicity and disparity of scales is an essential source of computational complexity. The multilevel algorithms address the problem under consideration at a hierarchy of scales, typically treating each with a method that is local to that particular scale. The proposed workshop will bring together junior researchers and world-class experts, mainly from North America, Western Europe, and Israel, to exhibit and discuss their recent research on multilevel computational methods for simulation and optimization in a wide variety of topics and applications. Together, the diverse backgrounds of the participants in the workshop and the planned activities are expected to expose new research directions in multilevel computational methods and to identify the most pressing challenges in this diverse field.

这笔赠款支持美国研究人员参加2013年4月29日至5月2日在以色列Rehospital魏茨曼科学研究所举行的“多级方法和优化”研讨会。计划中的讲座和小组讨论将涵盖偏微分方程等经典问题，以及网络搜索和数据挖掘等现代任务。 研讨会的演讲者和参与者来自各个学科，包括物理学、生物学、化学、经济学、环境和地球科学、计算机科学和工程。一个特别的两小时小组“多级计算的挑战：我们应该把我们的努力和我们的研究生？“计划在第二天举行。 大量变量的模拟和优化问题的多级求解方法是科学和工程中几乎所有学科的核心和重要问题。这些方法非常强大，因为它们利用了大多数计算问题具有多个尺度的事实。这种多尺度的概念可能有许多不同的伪装，包括时间和空间，像素，粒子，蛋白质或网页。这种尺度的多样性和不一致性是计算复杂性的重要来源。多层次算法解决的问题，考虑在一个层次的规模，通常处理每一个方法，是本地的特定规模。 拟议的研讨会将汇集初级研究人员和世界级的专家，主要来自北美，西欧和以色列，展示和讨论他们最近的研究多级计算方法的模拟和优化在各种各样的主题和应用。 总之，讲习班和计划中的活动的参与者的不同背景，预计将暴露在多级计算方法的新的研究方向，并确定在这个不同的领域最紧迫的挑战。
