Heuristic Algorithms for Placing Geomagnetically Induced Current Blocking Devices
Minseok Ryu, Ahmed Attia, Arthur Barnes +3
We propose a new heuristic approach for solving the challenge of determining optimal placements for geomagnetically induced current blocking devices on electrical grids. Traditiona…
Robust A-Optimal Experimental Design for Bayesian Inverse Problems
Ahmed Attia, Sven Leyffer, Todd Munson
Optimal design of experiments for Bayesian inverse problems has recently gained wide popularity and attracted much attention, especially in the computational science and Bayesian i…
Polytopic Superset Algorithm for Nonlinear Robust Optimization
Bowen Li, Kibaek Kim, Sven Leyffer
Nonlinear robust optimization (NRO) is widely used in different applications, including energy, control, and economics, to make robust decisions under uncertainty. One of the class…
Compact representations of structured BFGS matrices
Johannes J. Brust, Zichao, Di +2
For general large-scale optimization problems compact representations exist in which recursive quasi-Newton update formulas are represented as compact matrix factorizations. For pr…
Doing Moore with Less -- Leapfrogging Moore's Law with Inexactness for Supercomputing
Sven Leyffer, Stefan M. Wild, Mike Fagan +4
Energy and power consumption are major limitations to continued scaling of computing systems. Inexactness, where the quality of the solution can be traded for energy savings, has b…
