A Hybrid Direct-Iterative Method for Solving KKT Linear Systems
Shaked Regev, Nai-Yuan Chiang, Eric Darve +4
We propose a solution strategy for linear systems arising in interior method optimization, which is suitable for implementation on hardware accelerators such as graphical processin…
Solving realistic security-constrained optimal power flow problems
Cosmin G. Petra, Ignacio Aravena
We present a decomposition approach for obtaining good feasible solutions for the security-constrained alternating-current optimal power flow (SCACOPF) problem at an industrial sca…
Another source of mesh dependence in topology optimization
Miguel A. Salazar de Troya, Geoffrey M. Oxberry, Cosmin G. Petra +1
The topology optimization community has regularly employed nonlinear programming (NLP) algorithms from the operations research community. However, these algorithms are implemented…
Large-scale Optimization with Linear Equality Constraints using Reduced Compact Representation
Johannes J. Brust, Roummel F. Marcia, Cosmin G. Petra +1
For optimization problems with linear equality constraints, we prove that the (1,1) block of the inverse KKT matrix remains unchanged when projected onto the nullspace of the const…
