Choosing a Math Programming Solver

In this eBook, we guide you through the step-by-step process of choosing a mathematical programming solver – so that you can find the best solver for your business requirements.

In this “Choosing a Math Programming Solver” eBook, you will learn:

  • The key criteria to consider when choosing a commercial or open-source solver – whether you’re starting a mathematical optimization project or already involved in one – including Budget and Licensing, Performance and Scalability, Professional Support, Active Development, Deployment, Ease of Use, and the Complexity of Switching.
  • The common scenarios that indicate it’s time to switch to a more robust solver like Gurobi.
  • How to successfully switch to Gurobi from your current solution.

New Directions for Optimization


In this video, Gurobi CEO and Co-founder Ed Rothberg discusses our motivations for some of the recent features we’ve added to the Gurobi Optimizer. We’ll then look at recent developments in the field and talk about how they are influencing our thinking about potential future directions.



 
  • Switching to Gurobi
  • Switching to Gurobi from CPLEX
  • Switching to Gurobi from Open Source Solvers

Switching to Gurobi

Switching solvers may seem like a daunting task, but it’s typically straightforward. New customers regularly tell us migrating was easier than they expected, and that they are happy they made the switch to Gurobi. Below are four things we do to make it easy to get started with Gurobi:

  • Provide a wide range of interfaces, so you can work in the environment you are most comfortable with
  • Keep the interfaces simple and intuitive to reduce your learning curve
  • Include Quick Start and Reference Guides, and Video Overviews on using the Gurobi Optimizer
  • Provide support for both MPS and LP file formats

Switching to Gurobi from CPLEX

Customers have told us that, once you understand a few key concepts, the migration process from CPLEX to Gurobi is straightforward and typically quite quick. In this page, we take you through the steps to migrating from CPLEX™ to Gurobi including:

  • Building the model
  • Setting Solver Parameters
  • Computing and Extracting the Solution

In addition, you can also see a list of code examples, across a range of programming languages, on our code examples page.

Switching to Gurobi from Open Source Solvers

We know there are a range of solvers, free and paid, to choose from. We also know that for some situations a free solver might be all that you need. We can help you better understand your choices among free solvers, their relative performance, and some questions to ask yourself in deciding what type of solver is right for you. Specifically, on this page we cover the following topics:

  • A list of some of the leading free linear and mixed-integer programming solvers
  • Relative solver performance comparisons
  • When a free solver may be the best choice
  • A general comparison of free vs. commercial solvers
