A Globally Convergent Linearly Constrained Lagrangian Method for Nonlinear Optimization

For optimization problems with nonlinear constraints, linearly constrained Lagrangian (LCL) methods sequentially minimize a Lagrangian function subject to linearized constraints. These methods converge rapidly near a solution but may not be reliable from arbitrary starting points. The well known example MINOS has proven effective on many large problems. Its success motivates us to propose a glo...

Inversion of Gravity Data by Constrained Nonlinear Optimization based on nonlinear Programming Techniques for Mapping Bedrock Topography

A constrained nonlinear optimization method based on nonlinear programming techniques has been applied to map geometry of bedrock of sedimentary basins by inversion of gravity anomaly data. In the inversion, the applying model is a 2-D model that is composed of a set of juxtaposed prisms whose lower depths have been considered as unknown model parameters. The applied inversion method is a nonli...

A REDUCED HESSIAN METHOD FOR LARGE SCALE CONSTRAINED OPTIMIZATION by

We propose a quasi Newton algorithm for solving large optimization problems with nonlinear equality constraints It is designed for problems with few degrees of freedom and is motivated by the need to use sparse matrix factorizations The algorithm incorporates a correction vector that approximates the cross term ZWY pY in order to estimate the curvature in both the range and null spaces of the c...
