Two-stage stochastic optimization for optimal power flow under renewable generation uncertainty
Dzung Phan, Soumyadip Ghosh
Article No.: 2
DOI: 10.1145/2553084

We propose a two-stage stochastic version of the classical economic dispatch problem with alternating-current power flow constraints, a nonconvex optimization formulation that is central to power transmission and distribution over an electricity...

GDCSim: A simulator for green data center design and analysis
Sandeep K. S. Gupta, Ayan Banerjee, Zahra Abbasi, Georgios Varsamopoulos, Michael Jonas, Joshua Ferguson, Rose Robin Gilbert, Tridib Mukherjee
Article No.: 3
DOI: 10.1145/2553083

Energy-efficient data center design and management has been a challenge of increasing importance in the past decade due to its potential to save billions of dollars in energy costs. However, the state of the art in design and evaluation of data...

Indemics: An interactive high-performance computing framework for data-intensive epidemic modeling
Keith R. Bisset, Jiangzhuo Chen, Suruchi Deodhar, Xizhou Feng, Yifei Ma, Madhav V. Marathe
Article No.: 4
DOI: 10.1145/2501602

We describe the design and prototype implementation of Indemics (_Interactive; Epi_demic; _Simulation;)—a modeling environment utilizing high-performance computing technologies for supporting complex epidemic...

Data-driven simulation of complex multidimensional time series
Lee W. Schruben, Dashi I. Singham
Article No.: 5
DOI: 10.1145/2553082

This article introduces a new framework for resampling general time series data. The approach, inspired by computer agent flocking algorithms, can be used to generate inputs to complex simulation models or for generating pseudo-replications of...

Multidimensional stochastic approximation: Adaptive algorithms and applications
Mark Broadie, Deniz M. Cicek, Assaf Zeevi
Article No.: 6
DOI: 10.1145/2553085

We consider prototypical sequential stochastic optimization methods of Robbins-Monro (RM), Kiefer-Wolfowitz (KW), and Simultaneous Perturbations Stochastic Approximation (SPSA) varieties and propose adaptive modifications for multidimensional...
