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 manuao 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 manuall write new ones as you can use the modeling language and the solver separately: You are commenting using your Twitter account. An automatic script to compile your own mex interface.


Several examples and well-known optimization problems are discussed, modeled, and solved using glpk. The GLPK package includes the following main components: If you have other resources that you would like to see added here, just drop me a line!

There is now an evolving wikibook on GLPK: Further the output of glpsol can be formatted using c-style printf statements combined with if and for statements. I will merge your comment with the main article. This file should be edited according to the users requirements.


Although the performance 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. GMPL is extremely easy to learn Consider the example below — nothing more to say.

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.

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. There are also other ways to contact the FSF.
