An augmented Lagrangian method for distributed optimization
We propose a novel distributed method for convex optimization problems with a certain separability structure. The method is based on the augmented Lagrangian framework. We analyze its convergence and provide an application to two network models, as well as to a two-stage stochastic optimization problem. The proposed method compares favorably to two augmented Lagrangian decomposition methods kno...
متن کاملShape Analysis for Augmented Topological Shape Descriptor
In this work we propose a scheme for analysis of the shape of a 3D model. We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes of the graph represent different components of the model, and we propose to analyze their shape separately. Shape characteristics such as taper/enlargement, average curvature...

15 صفحه اولAn augmented Lagrangian optimization method for inflatable structures analysis problems
1. Abstract This paper describes the development of an augmented Lagrangian optimization method for the numerical simulation of the inflation process in the design of inflated space structures. Although the Newton-Raphson scheme has proved to be efficient for solving many non linear problems, it can lead to lacks of convergence when it is applied to the simulation of the inflation process. As a...
متن کاملSmoothing augmented Lagrangian method for nonsmooth constrained optimization problems
In this paper, we propose a smoothing augmented Lagrangian method for finding a stationary point of a nonsmooth and nonconvex optimization problem. We show that any accumulation point of the iteration sequence generated by the algorithm is a stationary point provided that the penalty parameters are bounded. Furthermore, we show that a weak version of the generalized Mangasarian Fromovitz constr...
