The GLPK (GNU Linear Programming Kit) package is intended for solving large-scale linear programming (LP), mixed integer programming (MIP), and other related problems.
GUSEK provide an open source LP/MILP IDE for Win32, packing a custom version of the SciTE editor linked to the GLPK standalone solver.




Classic LINDO's simple interface and straightforward model expression style make it easy to learn and use. Classic LINDO is appropriate for building and solving moderately sized linear and integer models.


An optimization package oriented on solving linear, integer and goal programming problems.

GNU MathProg is a high-level language for creating mathematical programming models. MathProg is specific to GLPK, but resembles a subset of AMPL.
The FICO Xpress Optimizer is a commercial optimization solver for linear programming, mixed integer linear programming, convex quadratic programming, convex quadratically constrained quadratic programming, and other problems.
