glpk

The GLPK (GNU Linear Programming Kit) package is intended for solving large-scale linear programming (LP), mixed integer programming (MIP), and other related problems. It is a set of routines written in ANSI C and organized in the form of a callable library.

GLPK supports the GNU MathProg language, which is a subset of the AMPL language.

The GLPK package includes the following main components: - Revised simplex method. - Primal-dual interior point method. - Branch-and-bound method. - Translator for GNU MathProg. - Application program interface (API). - Stand-alone LP/MIP solver.
