Solving Constraint Integer Programs
file reader for polynomial mixed-integer programs in PIP format
This reader allows to parse and write PIP files with linear and polynomial constraints and objective. For writing, linear (general and specialized), quadratic, and "and" constraints are supported. Also abspower, bivariate, and nonlinear constraints may be written, if they are representable as polynomials.
The PIP format is similar to the LP format and defined at http://polip.zib.de/pipformat.php .
