This page contains a collection of Mixed Integer Nonlinear Programming (MINLP) test problems in AMPL. A student version of AMPL is available for free which can handle problems with up to 300 variables or constraints.

The integer variables, Special Ordered Sets and priorities are specified through an int file. Note that the int file is not required by default as AMPL allows the definition of integer variables.

In the Table below, the following column headings are used:

heading meaning
NAME the name of the problem, click for a short reference
mod file the corresponding ampl model file
dat file the corresponding ampl data file
int file the corresponding [int_format integer file]
CUTE classification Classification as Nonlinear Program (NLP)
#int the number of integer variables
convex (Y/N) depending on whether the problem is convex or not; (Y*=pseudo-convex)
f(x) objective value of NLP relaxation
f(x*) optimal objective value or best solution found

The collection is available as a single [MacMINLP.tar.gz tar file] (simply gunzip and tar xf the file) or as individual problems below or as a collection of stub.nl files which can be interpreted by an AMPL solver interface and do not require the AMPL itself. You can also get all models and data files as a gzip'ed tar ball of the mod/dat files and a file with the MINLP AMPL commands used to run the problems is also available.

Click on the NAME of the problem for a short description. The complete list of descriptions can be found in the MINLP Comments. Finally, a list of updates and changes to the AMPL files and the int files is MINLP Updates.
