Implementation of multiple-corrections and presolve enhancement in the interior-point linear programming code LIPSOL
Multiple correction was introduced by Gondzio (5) to accelerate the convergence of iterates generated by primal-dual interior-point algorithms for linear programming. In this work, we implement the multiple correction ...
A framework for managing models in nonlinear optimization of computationally expensive functions
One of the most significant problems in the application of standard optimization methods to real-world engineering design problems is that the computation of the objective function often takes so much computer time (sometimes ...
A large-scale trust-region approach to the regularization of discrete ill-posed problems
We consider the problem of computing the solution of large-scale discrete ill-posed problems when there is noise in the data. These problems arise in important areas such as seismic inversion, medical imaging and signal ...
