Nonlinear Averages and Convergence of Penalty Trajectories in Convex Programming,h conditions ensuring existence and uniqueness of such trajectories, as well as their convergence towards a particular solution of the convex program. This particular limit point is characterized as the unique solution of a nested hierarchy of optimization problems. The construction leading to this

Case Studies in Complementarity: Improving Model Formulation,ling languages such as GAMS and AMPL. Sometimes the models generated are poorly specified, either because the function is undefined near the solution or the problem is ill-conditioned or singular. In this paper, we look at information provided by the PATH solver about the model that can be used to i

Convergence of a Smoothing Continuation Method for Mathematical Progams with Complementarity Constrticular, we show that under the linear independence constraint qualification and an additional condition called the asymptotic weak nondegeneracy, the limit of KKT points satisfying the second-order necessary conditions for the perturbed problems is a B-stationary point of the original MPEC. The not

Stable Solution of Variational Inequalities with Composed Monotone Operators,tinuous and monotone operator and ∂. is the subdifferential of a proper convex lower semicontinuous functional. The analysis is oriented to methods coupling successive approximation of the variational inequality with the proximal point algorithm as well as to related methods using regularization on

A Projection-Proximal Bundle Method for Convex Nondifferentiable Minimization, Hilbert space. We study an inexact proximal point algorithm under mild conditions on accuracy tolerances that ensure weak convergence of its iterates to a solution, or strong convergence when . is boundedly well-set. We also give a bundle method for minimizing . At each iteration, it finds a trial

Proximal and Dynamical Approaches to Equilibrium Problems,mber of problems arising in mathematical economics, optimization and operations research. Inspired by numerical methods developed for variational inequalities and motivated by recent advances in this field, we propose several ways (including an auxiliary problem principle, a selection method, as wel

Error Bounds for Regularized Complementarity Problems, by a small positive parameter. We study properties of the limit point of the solution to the regularized problem. We also derive local error bounds on the distance from the solution to its limit point, expressed in terms of the regularization parameter.
