Hoffman constant of the argmin mapping in linear optimization
J. Camacho, M. J. Cánovas, H. Gfrerer +1
The main goal of this paper is to provide a point-based expression for the Hoffman constant of the argmin mapping in linear optimization, understood as the sharp Lipschitz constant…

Subdifferentials and Stability Analysis of Feasible Set and Pareto Front Mappings in Linear Multiobjective Optimization
María J. Cánovas, Marco A. López, Boris Mordukhovich +1
The paper concerns multiobjective linear optimization problems in R^n that are parameterized with respect to the right-hand side perturbations of inequality constraints. Our focus…

Lipschitz modulus of linear and convex systems with the Hausdorff metric
Gerald Beer, María J. Cánovas, Marco A. López +1
This paper analyzes the Lipschitz behavior of the feasible set in two parametric settings, associated with linear and convex systems in R^n. To start with, we deal with the paramet…
