Example Code and Optimization Models Overview. This page contains links to dozens of examples across a range of APIs that you can review to help you jump start your work with Gurobi by exploring the three tabs below In addition to the examples listed here, if you are switching from another solver, you may be interested in the helpful information contained on the following pages to help make your migration even easier Functional Examples. The Gurobi distribution includes an extensive set of examples that illustrate commonly used features of the Gurobi libraries. Most examples have versions for C, C, C, Java, Visual Basic and Python. A few, however, illustrate features that are specific to the Python interface. A brief note for users of the Gurobi MATLAB and R interfaces our interfaces to these languages are built around the assumption that you will use the rich matrix oriented capabilities of the underlying languages to build your optimization models. Thus, our examples for these languages dont attempt to show you how to build models. We have instead chosen to provide a few simple examples that demonstrate how to pass matrices into our interface. We recommend that you begin by reading the overview of the examples. However, if youd like to dive directly into specific examples, the. Gurobi. distribution, organized by basic function.

We know many people like to start out by looking for examples of models that, even though not exact to their situation, give them a starting point that they can work from to build their own model. One of the best books weve come across to help people think about how to model is the fifth edition of Model Building in Mathematical Programming, by H. P. Williams. You can find it on Amazon. However, the book does not actually show you the code required to build the example models. As a result, we have created implementations in Python using Gurobi for many of the examples. Our goal is to have you use the H.
