Introduction

The GLPK package supplies a solver for large scale linear programming (LP) and mixed integer programming (MIP). The GLPK project is hosted at http://www.gnu.org/software/glpk.

It has two mailing lists: help-glpk@gnu.org and bug-glpk@gnu.org. To subscribe to one of these lists, please, send an empty mail with a Subject: header line of just "subscribe" to the list.

Project GLPK for Windows delivers executables for Windows.

Download

The latest source release of GLPK is available at ftp://ftp.gnu.org/gnu/glpk/.

The executables supplied by GLPK for Windows are available at http://sourceforge.net/projects/winglpk/

Installation

Download and unzip the distribution zip file. The executables and dynamic link libraries for 32 bit Windows can be found in directory w32, those for 64 bit Windows can be found in directory w64.

The libraries have to be in the search path for binaries when executing the standalone solver glpsol.exe. Therefore it is suggested to copy the DLLs to %SystemRoot%nsystem32 (e.g. c:\windows\system32).

The documentation can be found in directory doc. If you want to use the GNU Math Programming Language (GMPL), please read gmpl.pdf. If you want to use the library in your own coding, please, refer to glpk.pdf.

Quick Guide

Glpsol is a console application. To use it you have to open a console window. Under Windows this is done by starting the program cmd.exe.

Glpsol has a lot of command line parameters. You can enumerate them with

glpsol.exe --help

The problem data is specified in a model file and optional data files. You can find examples in the examples directory of the distribution tar ball.

To solve a model (e.g. examples/tsp.mod) pass the model file name as a parameter to glpsol:

glpsol -m examples/tsp.mod
