Abstract

Interior-point approach is one kind of most important and effective methods for nonlinear inequality-constrained optimization, whereas classic augmented Lagrangian methods are very efficient in solving nonlinear equality-constrained optimization and convex optimization. The newly research has shown that the interior-point augmented Lagrangian function can be of higher-order smoothness, and is convex when the original optimization problem is convex. These nice properties make the novel augmented Lagrangian applicable and effective not only for convex optimization but also for non-convex optimization problems. We summarize our interior-point augmented Lagrangian methods on non-convex and convex optimization, and point out some next research topics.
