An alternating structured trust region algorithm for separable optimization problems with nonconvex constraints

Xue, Dan; Sun, Wenyu; Qi, Liqun - In: Computational Optimization and Applications 57 (2014) 2, pp. 365-386

In this paper, we propose a structured trust-region algorithm combining with filter technique to minimize the sum of two general functions with general constraints. Specifically, the new iterates are generated in the Gauss-Seidel type iterative procedure, whose sizes are controlled by a...
