2002-06-26import of glpk-3.0.7 provided in PR pkg/16691 by Kent Polk ↵dmcmahill1-0/+21
<kent@tiamat.goathill.org> with some changes and finishing of the package by me. GLPK is a set of routines written in ANSI C and organized in the form of a callable library. This package is intended for solving large-scale linear programming (LP), mixed integer linear programming (MIP), and other related problems. GLPK includes the following main components: * implementation of the primal/dual simplex method; * implementation of the primal-dual interior point method; * implementation of the branch-and-bound procedure (based on the dual simplex method); * application program interface (API); * GLPK/L, a modeling language intended for writing LP/MIP models; * GLPSOL, a stand-alone program intended for solving LP/MIP problems either prepared in the MPS format or written in the GLPK/L modeling language.
