MINOS 5.5

MINOS 5.5

Description

MINOS (invented by Bruce Murtagh and Michael Saunders) is a software package for solving large-scale optimization problems (linear and nonlinear programs).

It is especially effective for linear programs and for problems with a nonlinear objective function and sparse linear constraints (e.g., quadratic programs). MINOS can also process large numbers of nonlinear constraints. The nonlinear functions should be smooth but need not be convex.

Hardware / Software / Interface

MINOS is implemented in Fortran 77 and distributed as source code. It is intended for any machine with a reasonable amount of memory and a Fortran compiler. It may be called from a driver program (typically in Fortran, C or MATLAB). MINOS may also be used as a stand-alone package, reading data in the MPS format used by commercial mathematical programming systems.

Key Benefits


	Numerical stable algorithms; for example, a reliable sparse LU basis package.
	Warm start capability.
	Needs only first derivatives.
	Optional data input from industry standard MPS files.
	A practical anti-degeneracy procedure.
	Efficient handling of linear constraints and bounds.
	Automatic scaling of linear and nonlinear constraints.
	Provision for internal problem modifications.

Application


	General-purpose linear programming and nonlinear programming where functions and gradients are not excessively expensive.
	Engineering, Economics, Finance, Agricultural Economics.
	Optimal control, Nonlinear networks, Trade models, Portfolio analysis, Spatial equilibrium.
	MINOS is heavily used as a nonlinear solver for the algebraic modeling systems GAMS and AMPL.
