WebWe first establish an ergodic convergence rate result of inexact ALM that uses constant penalty pa-rameters or geometrically increasing penalty parameters. Based on the convergence rate result, we apply Nesterov’s optimal first-order method on each primal subproblem and estimate the iteration complexity of the inexact ALM. WebIn this paper, we present novel algorithms for matrix recovery which utilize tech- niques of augmented Lagrange multipliers (ALM). The exact ALM (EALM) method to be proposed …

WebAbstract. First-order methods have been studied for nonlinear constrained optimization within the framework of the augmented Lagrangian method (ALM) or penalty method. We propose an improved inexact ALM (iALM) and conduct a unified analysis for nonconvex problems with either convex or nonconvex constraints. Under certain regularity conditions ...
