MINLPLib - A Collection of Test Models for Mixed-Integer Nonlinear Programming

The paper describes a new computerized collection of test models for mixed-integer nonlinear programming. Since there is no standard format for nonlinear models, the model collection is augmented with a translation server that can transform the models from their basic GAMS format into a number of other formats such as AMPL, BARON, LINGO, and MINOPT. The translation server can also be used to transform industrial models with confidential information in a way that allows many of these models to be distributed to the research community as highly relevant algorithmic test models.
