AMPL /MINOS
The AMPL /MINOS toolbox efficiently integrates the two well-known solvers MINOS and QPOPT, developed by the Stanford Systems Optimization Laboratory (SOL), with AMPL.
MINOS is a large-scale sparse general nonlinear solver, but solves also sparse linear and quadratic problems efficiently.
QPOPT is a dense convex quadratic solver that also solves non-convex quadratic programs.
Features and capabilities
-
AMPL can use MINOS and QPOPT as subproblem solvers resulting in faster and more robust code.
-
The dense QPOPT code is implemented to efficiently handle dense arrays.
-
All solver parameters and features are selectable.
-
It is possible to use warm starts for the SOL solvers, and further speed up sequences of optimization solutions.
-
The SPECS file input format is also possible to use.
