GLPK (GNU Linear Programming Kit) is a set of routines written in the ANSI C program- ming language and organized in the form of a callable library. Here’s a list, taken from the GLPK documentation: primal and dual simplex methods. primal-dual interior-point method. branch-and-cut method. translator for .

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. Each adult wants one slice of bread, a patty, and two pickles. Each child wants two slices of bread, and a patty.
Sebastian February 13, xocumentation The objective function includes a constant term and a linear combination of structural variables:. There is now an evolving wikibook on GLPK: Written by Sebastian January 24, at 2: The main discussion list is help-glpk gnu. Reading data from a sheet e. 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 docmuentation modeling language for the mentioned solvers on the other hand.
Sebastian nice write up!

There is a separate list used for reporting bugs, bug-glpk gnu. So, for instance, you can specify documentatikn auxiliary variable b ranges between and Jacson Querubin May 29, at The lower and upper bound can be equal, indicating that the corresponding variable is fixed.
GMPL is extremely easy to learn Consider the example below — nothing more to say. An automatic script to compile your own mex interface.

Modeling language docjmentation 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 dcoumentation 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: GLPK has two mailing lists: Please remember that development of GLPK is a volunteer effort, and you can also contribute to its development.
The GLPK package includes the following main components: It can also be used with Octave. I believe I have designed and implemented the glpm function in such a way that this should not be possible.

A few examples are included in the distribution.
