MacMINLP : ampl collection of Mixed Integer Nonlinear ProgramsThis directory 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:
The collection is available as a single 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. A file with the 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 here. Finally, a list of updates and changes to the AMPL files and the int files is here.
