Engineering Research Equipment: Equipment for Research in Applied and Computational Optimization

小行星9622200 将购买一个带有Solaris用户环境和两个75 Mhz处理器的20多处理器工作站，以支持应用优化中心的研究，该中心将进行应用和基础项目的混合。 研究将集中在应用优化和算法研究的主要领域。 重点研究的具体项目有：（1）水资源管理的决策模型，包括确定最佳替代供水策略的模型和算法的开发;（2）拥挤定价的有界流方法，使用新的非线性规划和变分不等式方法来确定控制城市街道网络拥挤的系统最佳收费;（3）新的下界算法和精确算法的计算算法开发，以解决NP难的组合优化问题;（4）分子构象和蛋白质折叠算法的开发和实现，以实现非凸能量函数的全局最小化。 这些设备将改善上述重要项目的研究环境。 这些设备将使一个已经生产力很高的中心更加如此。 基础设施的改善应该导致新的发现或根本性的进步。

9622200 Hearn A SPARC station 20 Multiprocessor Workstation with Solaris User Environment and two 75 Mhz Processors will be acquired to support research in the Center for Applied Optimization where a mix of applied and fundamental projects are conducted. The research will focus on the major areas of applied optimization and algorithm research. The particular projects to be focused upon are: (1) decision modeling for water management, involving development of models and algorithms for determining optimal alternative water supply strategies; (2) bounded flow approach to congestion pricing using new nonlinear programming and variational inequality methods to determine system optimal tolls for controlling congestion in urban street networks; (3) computational algorithm development for new lower bound heuristics and exact algorithms to solve classes of NP-hard combinatorial optimization problems; and (4) molecular conformation and protein folding algorithm development and implementation for global minimization of nonconvex energy functions. The equipment will improve the research environment of the important projects identified above. The equipment will make an already productive center even more so. The improvements to the infrastructure should lead to new discoveries or fundamental advances.
