LAMPS

From NEOS

LAMPS = Linear programming, mixed integer programming

LAMPS (Linear and Mathematical Programming System) offers a primal and a dual simplex algorithm for the solution of linear programs, and a branch-and-bound algorithm for mixed integer programs. The linear programming method used for solution of nodes in the branch-and-bound tree is user selectable.

LAMPS also provides sensitivity analysis in terms of parametric variation of the right-hand side or objective function, and ranging.

LAMPS is designed for the solution of large problems, although it will operate efficiently on small- and medium-sized problems. Most standard input formats are acceptable, and output (solution) reporting is very flexible.

Mixed integer problems may define data in terms of S1 or S2 sets, general integer, binary, and semi-continuous variables.

Algorithms of LAMPS are also available for direct use with MAGIC (a matrix generation and reporting system) and [gams.html GAMS.]

Software is normally supplied only in object code and executable form. Versions are available for 80386/486 MS-DOS machines, most Unix workstations, VAX, Prime, Convex, and Cray. Algorithms and data/matrix manipulation functions of LAMPS are available as a subroutine library.
