Abstract
A trust-region SQP method for general nonlinear constrained optimization without derivatives is proposed. The trust-region step is computed by a Byrd-Omojokun-like approach. An active-set strategy is used to handle bound constraints and inequality constraints. The objective and constraint functions are approximated by local linear or quadratic interpolation. In this work, we want to examine different approximation techniques.
