MiniZinc constraint programming system
MiniZinc is a very interesting constraint programming system/modeling language with a high level syntax. From the MiniZinc page:
MiniZinc is a medium-level constraint modelling language. It is high-level enough to
express most constraint problems easily, but low-level enough that it can be mapped
onto existing solvers easily and consistently. It is a subset of the
higher-level language Zinc. We hope it will be adopted as a standard by the
Constraint Programming community.
FlatZinc is a low-level solver input language that is the target language for
MiniZinc. It is designed to be easy to translate into the form required by a
solver.
Some important links:
Solvers
In order to solve a problem stated in the MiniZinc modeling language, a FlatZinc solver must be used. Here is a listing of some FlatZinc solvers.
- The MiniZinc distribution contains the following solvers:
- Gecode/FlatZinc. Requires that Gecode is installed.
- The ECLiPSe Constraint Programming System
library(minizinc) (and library(flatzinc) provides 3 different solvers which corresponds to ECLiPSe's "normal" solvers:
* fzn_ic, see library(ic)
* fzn_fd, see library(fd)
* fzn_eplex, see library(eplex), which in turn can use different solvers, e.g. the commercial Cplex, XPress-MP, or the open source COIN solvers symclp, clpcbc.
- SICStus Prolog (from version 4.0.5 and onward): Zinc interface - library(zinc)
- JaCoP (Java Constraint Programming solver): Fz2jacop
- Google or-tools
- SCIP (Solving Constraint Integer Programs)
- fzntini. A SAT solver based on Tinisat.
- fzn2smt: Using SMT/SAT.
- Neng-Fa Zhou's BProlog solver, newer version for MiniZinc Challenge 2012: flatzinc2012.pl
- Picat, section "MiniZinc Challenge" (this was the version we submitted to MiniZinc Challenge 2013)
- Mistral 2.0
- Numberjack
- MiniCSP clause learning CSP solver (based on MiniSAT)
- fz_izplus (note: the web page is in Japanese)
- MinisatID: SAT/Lazy solver
- Opturion CPX Optimizer: CP/SAT solver
Utilities
mzn_show.pl
Perl program mzn_show.pl
Since version 1.0 MiniZinc don't support the output []
anymore in the external solvers (e.g. all except the minizinc
solver), and
it can be hard to see structured output, e.g. matrices. This program gives the result somewhat nicer output. I blogged about the program (first version) here: Miscellaneous news.
Usage: solver problem.mzn | mzn_show.pl "{parameter}"
The parameters are:
- {tr:from:to:}
: translate digit to another digit/character
- {trvar:var:from:to:}
: translate digit to another digit/character for a specific variable var
- {trtr:from_string:replacement_string:}
: translates all digits in from_string
to the corresponding digit/character in replacement_string
(inspired from the Unix tr command)
- {trtrvar:var:from_string:replacement_string:}
: as trtr
but for a specific variable var
- {nospaces}
: don't show space after character
- {noprintf}
: don't try to be clever with printf stuff
- {noresult}
: don't print the numerical result (just the translations)
- {nonogram}
: shortcut for {trtr:12: #} {nospace} {noresult}
Example: for showing a nicer picture of a Nonogram:
flatzinc nonogram_create_automaton2.fzn | mzn_show.pl "{tr:1: :} {tr:2:#:} {nospace}"
Where the {tr:from:to:} means translate digit from
to character to
, and {nospace}
means that no spaces are shown after each digit/character.
This is now probably better written with trtr
:
flatzinc nonogram_create_automaton2.fzn | mzn_show.pl "{trtr:12: #:} {nospace}"
mzn.pl
I have also created a Perl program for handling all the different solvers from the command line, as well as changing the model parameters etc. The program may be obtained upon request by mailing me (hakank@gmail.com).
Emacs mode
minizinc.el is a simple MiniZinc (major) mode for Emacs, heavily based on the Prolog model prolog.el (written by Masanobu UMEDA); to be honest I mostly replaced "Prolog" with "MiniZinc" and some other adjustments. The file still have the interactive mode etc but that will (of course) not work for MiniZinc since it don't work like Prolog. I mostly use it for syntax highlightning and commenting.
My MiniZinc models
The following is a list of (some of) my models: simple puzzles and not so simple puzzles, standard operation research / integer programming examples, and some global constraints (that are not in the MiniZinc globals.mzn). Some are just examples of modelling in MiniZinc.
Almost all models are commented with sources or inspirations, and quite a few have the main constraints generalized as a predicate.
All files (models, datafiles, etc) are (or will be) available at the Github repository: github.com/hakank/hakank/tree/master/minizinc.

Global constraints (mostly decompositions)
Here are some implementations of the global constraints (mostly as decompositions) which are not already implemented in the MiniZinc globals.mzn, described in the great collection Global Constraint Catalog. Here are also some decompositions not in the catalogue or test of built-in constraints.
Name clashes: If there exists a file in default directory with the same name as one of the global constraints defined in "global.mzn", there will be a name clash. If that happens, just rename the file in the default directory to something else, e.g. constraint_me.mzn.
