Stability properties of the problem of minimizing a (nonconvex) linear-quad-ratic function over an Euclidean ball, known as the trust-region subproblem, are studied in this paper. We investigate in detail the case where the linear part of the objective function is perturbed and obtain necessary and sufficient conditions for the upper/lower semicontinuity of(More)
In this talk, we apply some tools of nonsmooth analysis and generalized differentiation to establish necessary condition for Pareto optimal solutions of a non-smooth semi-infinite multiobjective optimization problem (SIMOP for brevity) via Chankong-Haimes method. Sufficient condition for Pareto optimal solutions of a SIMOP are presented by means of(More)
