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 . Version; Authorized Users; Platforms; Modules. 2 Running GLPK on CIRCE/SC; 3 Documentation. Home Page, User Guides.

Along with these constraints, each variable, both structural dcoumentation auxiliary, comes with a pair of possibly infinite bounds. Another way to subscribe is to use the mailing list interface; see Help-glpk and Bug-glpk.

Noli February 13, at Right now, this library does not support any of those bells and whistles; it just allows basic primal simplex solving. Subscribe to comments with RSS. If you have other resources that you would like to see added here, just drop me a line!


Several examples and well-known optimization problems are discussed, modeled, and solved using glpk. The constraints each include the name of an auxiliary variable and a linear combination of structural variables:. Each bound contains the name of a variable, and a low and high boundary. Sebastian nice write up! If that command fails because you do not have the required public key, run the following command to import it:.

To subscribe to these or any GNU mailing lists, please send an empty mail with a Documentahion Sebastian Pokutta’s Blog Mathematics and related topics. If you think you have found a bug in GLPK, then please send as complete a report as possible to bug-glpk gnu. There is a separate list used for reporting bugs, bug-glpk gnu.


Also there are a variety of interfaces available for GLPK: Enter your email address to subscribe to this blog and receive notifications of new posts by email.

To model this, we divide adults into adults chaperoning kinds ak and adults chaperoning chickens ac. GLPK has two mailing lists: 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. From the project homepage: If I understand the internals of Racket correctly, making use of this would require separately compiling a C stub that establishes a jump buffer and uses setjmp before calling into each GLPK library function.

Exact simplex algorithm integrated GLPK comes with the option to use an exact simplex implementation using rationals, i. You have three kinds of guests: The GLPK package includes the following main components: It can also be found on one of our FTP mirrors ; please use a mirror if possible.

Makhorin, allowing you to solve linear optimization problems. 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. Noli February 22, at The result is a list containing the maximal or minimal value of the objective function, along with a list of lists mapping structural variables to the values that produce that optimal value, unless no solution is possible.

Finally, the set of bounds provides bounds for both the auxiliary and structural variables. Email required Address never made public. I merged the links back into the main article. Okay, so what kind of constraints are possible?


Children, Adults, and Chickens. Each adult wants one slice of bread, a patty, and two pickles. Sebastian February 13, at Also most of the parameters of docmentation glpsol standalone solver can be controlled via the GUI.

It can also be used with Octave. The linear programming problem can be formulated as follows: Noli February 12, at 9: GMPL is extremely easy to learn Consider the example below — nothing more to say. Possibility to use GLPK through a simple matlab command, namely glpk.

For details on submitting a bug report, please see the section Report a Bug below. GLPK is currently being maintained by mao gnu.

There are also other ways to contact the FSF. There are several interfaces for Python: An automatic script to compile your own mex interface. 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 docmuentation free but you need to use a different maybe more powerful solver like cplex or CBC you can dochmentation 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: Leave a Reply Cancel reply Enter your comment here 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.
