GLPK comes with the option to use an exact simplex implementation using rationals, i.e., no rounding errors etc. There are many interfaces for GLPK available including Matlab, Octave, R, Java, Python (see below).

The GUSEK GUI (see below) provides a nice user interface to use GLPK on Windows, Mac OS X, and Linux (for the latter two using Wine). GUI for Windows, Mac OS X, and Linux available.If you have the feeling at some point that GNU MathProg is a cool modeling language (afterall it is almost AMPL but free) but you need to use a different (maybe more powerful) solver like cplex or CBC you can still continue using your old models written in GNU MathProg or even write new ones as you can use the modeling language and the solver separately: Using glpsol (the standalone solver) with the appropriate parameter set, you can write cplex-lp or mps files for example that you can use as input for e.g., cplex.Ĭonsider the example below - nothing more to say. Modeling language and solver can be used independently.

Also, GLPK comes with a lot of examples that give a pretty good overview on how to formulate optimization problems in GNU MathProg. This language is very versatile and modeling with it is extremely easy. GLPK comes with its own modeling language, the GNU MathProg Language (GMPL) which is a subset of AMPL. GLPK comes with the modeling language GMPL which is compatible with AMPL.
The solver is a branch-and-cut solver generating Gomory’s mixed integer cuts, mir cuts, mixed cover cuts, and clique cuts. The latter format are the models generated by the modeling language GMPL that comes with GLPK. This solver can read either mps, cplex-lp, or GNU MathProg files. GLPK can be either used as a library, or as a stand-alone solver which is called glpsol.

No hassle with compilation problems such as missing libraries etc nothing is more frustrating than wanting to go ahead full speed and software problems jeopardize that. On Mac OS X, GLPK can be compiled and installed used the typical “./configure”, “make”, “make install” or alternatively the GUSEK Gui can be used via Wine (see below). Most linux distributions come either with a copy of GLPK installed or GLPK can be installed via the respective package manager.
#Textadept wiki download#
Beware, the “ glpk for windows” binaries seems to be outdated so do not use those and rather download GUSEK or get the latest binaries from the here. For Windows, glpk binaries can be obtained as part of the GUSEK GUI (see below). The installation of GLPK is really simple on almost all platforms. GLPK is released under the GPL and thus comes with the full source code. 10 reasons why you might want to use GLPK in class. If you encounter any problems using GLPK this is also the right place to seek help. There is also an official help-archive / mailing list with news and discussions. If you have other resources that you would like to see added here, just drop me a line! The GLPK package includes the following main components:
GLPK supports the GNU MathProg modeling language, which is a subset of the AMPL language. It is a set of routines written in ANSI C and organized in the form of a callable library. The GLPK ( GNU Linear Programming Kit) package is intended for solving large-scale linear programming (LP), mixed integer programming (MIP), and other related problems. Although the performance of the solver cannot match the performance of cplex, Gurobi, scip, or CBC, it has a lot of unique features on the one hand and glpk can be used as a modeling language for the mentioned solvers on the other hand. The GNU Linear Programming Kit (glpk) is a very versatile Mixed Integer Linear Programming solver that is especially well suited for teaching and research purposes.
