Gurobi Optimizer Technical Features and Details

An Optimization Solver Reimagined

The Gurobi Optimizer was designed from the ground up to be the fastest, most powerful solver available for your LP, QP, QCP, and MIP (MILP, MIQP, and MIQCP) problems. Our code was built to fully exploit parallelism. It’s not a sequential code that was parallelized, but a fundamentally parallel code that you can also choose to run sequentially. Our MIP cutting plane routines are second to none. We’ve also gone beyond cutting-edge versions of all the standard cutting planes and developed new classes of cuts available only in Gurobi. Our advanced MIP heuristics for quickly finding feasible solutions often produce good quality solutions where other solvers fall flat. Our barrier algorithms fully exploit the features of the latest computer architectures. And our APIs are designed to be lightweight, modern and intuitive, so as to minimize your learning curve while maximizing your productivity.

Unique Features

We have added a range of capabilities:

  • A Python API that provides the advantages of both a modeling language and a full programming language.
  • Support for models with multiple, competing objectives and two options to solve them.
  • The ability to directly solve models with piecewise-linear objective functions, to better capture certain non-linear problems.
  • The ability to express common modeling constructs like min or max or if/then at a higher level, making such models easier to build and maintain,
  • Powerful and flexible client-server and cloud capabilities to help you develop and deploy where and how you want to any number of users on a broad range of platforms.
Features Detail Benefit
Outstanding solve times
  • Gurobi has a history of leading public benchmarks and making continual improvements across a range of problem types.
  • Gurobi is tuned to optimize performance over a wide range of instances.
Add complexity to your model to better represent the real world, and still solve your model within the available time.
Problem types
  • Linear Programming (LP)
  • Mixed-Integer Linear Programming (MILP)
  • Quadratic Programming (QP)
  • Mixed-Integer Quadratic Programming (MIQP)
  • Quadratically Constrained Programming (QCP)
  • Mixed-Integer Quadratically Constrained Programming (MIQCP)
Model your problem the way that works best for you.
Extremely robust code
  • Robustness has several components: numerical stability, correctness of results, scalability with problem size and difficulty, and robustness of solve times over a range of model instances.
  • Gurobi is tested thoroughly for numerical stability and correctness using an internal library of over 10,000 models from industry and academia.
Have confidence in your results.
Programming and modeling languages
  • Object-oriented interfaces for C++, Java, .NET, and Python
  • Matrix-oriented interfaces for C, MATLAB, and R
  • Consistent intuitive design across all programming interfaces
  • Interfaces are lightweight, meaning that they are faster and use less memory
  • Links to standard modeling languages: AMPL, GAMS, AIMMS, and MPL
  • Links to Excel through Frontline Solvers
Maximize your productivity by working in the language you are most comfortable with.
Additional modeling features
  • Support for multiple objectives with flexibility in how they are prioritized
  • General constraints such as MIN/MAX, ABS, AND/OR, and indicator constraints
  • Algorithmic support for models with convex, piecewise-linear objective functions
More easily turn your model into code
Extensions for Python API
