What is Zimpl

Zimpl is a little language to translate the mathematical model of a problem into a linear or (mixed-) integer mathematical program expressed in .lp or .mps file format which can be read and (hopefully) solved by a LP or MIP solver.

Where does is run?

Zimpl is a command line program written in plain C and released under GNU GPL. It has been tested to compile under Linux/Intel, Solaris, Tru64, HPUX, IRIX, AIX and MacOS-X. Probably it will compile and run wherever GMP is available. Zimpl has even been successfully compiled for Windows using MinGW and the GCC as a cross compiler.

What's new in 2.05


The latest Version is 2.05. Download complete source code and documentation.
There is also a Debian package maintained by Joachim Reichel.
Differences to the older versions are described in the Changelog.
Precompiled binaries are also available.


If you find one (shouldn't be too difficult), it would be nice if you send a description or even better a working fix with a runnable example .zpl file to kochKlammeraffezib.de.


You need a solver for the problems generated by Zimpl. SCIP is a solver for mixed integer programs which can be linked directly with Zimpl. lp_solve is another solver which has an experimental integration of Zimpl. SoPlex is a good simplex solver for pure linear programs (LP).
For other available solvers, see the Decision Tree for Optimization Software / LP-Software.
