Complexity analysis of second-order line-search algorithms for smooth nonconvex optimization
Clément W. Royer, Stephen J. Wright
There has been much recent interest in finding unconstrained local minima of smooth functions, due in part of the prevalence of such problems in machine learning and robust statist…
Vulnerability Analysis of Power Systems
Taedong Kim, Stephen J. Wright, Daniel Bienstock +1
Potential vulnerabilities in a power grid can be exposed by identifying those transmission lines on which attacks (in the form of interference with their transmission capabilities)…
Coordinate Descent Algorithms
Stephen J. Wright
Coordinate descent algorithms solve optimization problems by successively performing approximate minimization along coordinate directions or coordinate hyperplanes. They have been…
PMU Placement for Line Outage Identification via Multiclass Logistic Regression
Taedong Kim, Stephen J. Wright
We consider the problem of identifying a single line outage in a power grid by using data from phasor measurement units (PMUs). When a line outage occurs, the voltage phasor of eac…
An SLP-Active Set Approach for Feasibility Restoration in Power Systems
Taedong Kim, Stephen J. Wright
We consider power networks in which it is not possible to satisfy all loads at the demand nodes, due to some attack or disturbance to the network. We formulate a model, based on AC…
Packing ellipsoids with overlap
Caroline Uhler, Stephen J. Wright
The problem of packing ellipsoids of different sizes and shapes into an ellipsoidal container so as to minimize a measure of overlap between ellipsoids is considered. A bilevel opt…
