Active-set prediction for interior point methods using controlled perturbations

1 code implementation27 Apr 2014 Coralia Cartis, Yiming Yan

We also find that a primal-dual path-following algorithm applied to the perturbed problem is able to accurately predict the optimal active set of the original problem when the duality gap for the perturbed problem is not too small; furthermore, depending on problem conditioning, this prediction can happen sooner than predicting the active set for the perturbed problem or when the original one is solved.
