Although the manuak of the solver cannot match the performance of cplexGurobiscipor CBCit 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.

From the project homepage:. If you have other resources that you would like to see added here, just drop me a line!
If you encounter any problems using GLPK this is also the right place to seek help. Several examples and well-known optimization problems are discussed, modeled, and solved using glpk.

There are several other tools available for GLPK. It can also be used with Octave.
GLPK-java is an interface for Java. Using the text output capabilities of GMPL almost any text-based output format can be generated that can be then used later in other programs. You can, for gkpk, use the output formatting to generate.
Also, using the table driver, you can generate output that you feed directly into Excel, g-docs, or Open Office either via copy-and-paste or by importing. Similarly you can access an sqlite3 database.

Sebastian Pokutta’s Blog Mathematics and related topics. From the project homepage: The GLPK package includes the following main components: 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.
GLPK comes with a stand-alone solver and a callable library GLPK can be either used as a library, or as a stand-alone solver which is called glpsol. It also has a feasibility pump. This language is very versatile and modeling with it is extremely easy. Modeling language and solver can be used independently 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.
GMPL is extremely easy to learn Consider the example below — nothing more to say. It comes with an integrated editor from which you can solve your models right away.

Also most of the parameters of the glpsol standalone solver can be controlled via the GUI. It can also write the result to back into the database. Further the output of glpsol can be formatted using c-style printf statements combined with if and for statements.
Exact simplex algorithm integrated GLPK comes with the option to use an exact simplex implementation using rationals, i. This is very helpful when using GLPK for research purposes and an exact solution is important e. Also there are a variety of interfaces available for GLPK: Possibility to use GLPK through a simple matlab command, namely glpk.
An automatic script to compile your own mex interface. A few examples are included in the distribution. There are several interfaces for Python: Reading data from a sheet e. Reading data from mdb table. Google Reddit Facebook Twitter. Written by Sebastian January 24, at 2: Sebastian nice write up! Noli February 12, at 9: I will merge your comment with the main article.
