INTRODUCTION ------------ 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 by a LP or MIP solver. If you use Zimpl for research and publish results, the best way to refer to Zimpl is to cite my Ph.d. thesis: @PHDTHESIS{Koch2004, author = "Thorsten Koch", title = "Rapid Mathematical Programming", year = "2004", school = "Technische {Universit\"at} Berlin", url = "http://www.zib.de/Publications/abstracts/ZR-04-58/", note = "ZIB-Report 04-58", } COMPILING --------- To compile Zimpl you need two additional librarys: - GNU Multiple Precision Arithmetic Library Version 4.2.2 or newer at http://www.swox.com/gmp - zlib Version 1.2.5 or newer at http://www.gzip.org/zlib/ Zimpl has not been tested with older versions of above librarys. GMP Version 3.x will not work for sure. If zlib.h and gmp.h and libgmp.a and libz.a are not at the usual places you have to adapt the Makefile, see below. On a Linux system you might succeed with just saying: make Otherwise: Whatever with GNU C : gmake Linux/x86 with Intel C : gmake COMP=intel Tru64 with Compaq C : gmake COMP=compaq Solaris with SUN Forte C : gmake COMP=sun AIX with VisualAge C : gmake COMP=ibm Windows with Cygwin/GCC : gmake COMP=gnu HPUX with HP C : gmake COMP=hp IRIX with SGI C : gmake COMP=sgi If your configuration is not in the list or does not work, you have to change the Makefile. Go to make/local an add a file make.<hostname_of_your_computer> There you can set the usual suspects like CC, CFLAGS, LDFLAG, and so on. The most likely reason that you can't compile, is that gmp.h or zlib.h are not in your include path (-I) or that libgmp.a oder libz.a are not in your library path (-L). Example: CPPFLAGS += -I/tmp/gmp/include LDFLAGS += -L/tmp/gmp/lib Have a look at Makefile and make/make.* to get an idea. On some MAC systems, GMP is installed under /sw/include and /sw/lib. If these are not contained in the library and include paths, you have to add them explicitly, as shown above. WINDOWS ------- You can just the through the source files into Visual Studio 2010. Please add the contents of the src/WIN directory to the files to be compiled. Make sure to set the following defines: WIN32 or WIN64 and INLINE= As for the libraries we recommend to replace gmp by MPIR - Multiple Precision Integers and Rationals version 2.4.0 or newer from http://mpir.org Furthermore, you need PCRE - Perl Compatible Regular Expressions version 8.12 or newer from http://www.pcre.org which should be compiled using the following two defines -DWITH_PCRE -DPCRE_STATIC CHECKING -------- Do a "make check" and look if it works. If not, compile again with an added "OPT=dbg" to the gmake invocation. If a failure in the 'subto' test is reported, this is to a difference in the behaviour of printf() and not a problem. INSTALLATION ------------ Copy bin/zimpl.*.opt to wherever you like. ALL GNULESS ----------- if you don't have gcc and gmake etc. You can try the following. Go to src and say "cc -O *.c -o zimpl". LICENSE ------- ZIMPL is under the GNU Lesser General Public License Version 3. See the file LICENSE for details. LATEST VERSION -------------- Can be found at http://zimpl.zib.de BUGS ---- Probably several. If you find one, send a description with runnable example .zpl file to [email protected] (Better even, send a working fix ;-) REMARK ------ If anything is changed in the code I would recommend recompiling without NDEBUG and NO_MSHELL defined. This will slow down the code considerably but will do a lot of consistency checking. In the source code are a lot of comments starting with /*lint ... and also a target in the Makefile. These are for flexelint (see http://www.gimpel.com) a very good version of lint. If you are interested in my settings used for this project, send me an email. THANKS ------ To Tuomo Takkula, Armin Fuegenschuh, Marc Pfetsch, Daniel Junglas, Joerg Rambau, Tobias Achterberg, Andreas Bley, Sebastian Orlowski, Bejamin Hiller, Ralf Borndoerfer, Martin Assmann, Nicolas Weber, Marc Moerig, Jens Hillmann, Dimitri Sverdlov, Joachim Reichel, Maciej Warszawski and all I forgot for their comments and bug reports. COMPLAINTS ---------- >/dev/null Have fun!
