Stability for trust-region methods via generalized differentiation

Qui, Nguyen - In: Journal of Global Optimization 59 (2014) 1, pp. 139-164

We obtain necessary and sufficient conditions for local Lipschitz-like property and sufficient conditions for local metric regularity in Robinson’s sense of Karush–Kuhn–Tucker point set maps of trust-region subproblems in trust-region methods. The main tools being used in our investigation...
