You have successfully installed version 10.0.0 of the Gurobi Optimizer.
You’ll find instructions for setting up your Gurobi license in this document, as well as a list of supported platforms, and Release Notes and guidelines for converting existing Gurobi code to run with this new version. Once you have finished browsing this document, you should refer to the
Detailed Release Notes, the
Quick Start Guide, the
Example Tour, the
Reference Manual, or the
Remote Services Reference Manual to get started using the Gurobi Optimizer.
Obtaining Your License
To obtain a Gurobi 10 license, you will need to visit the
Gurobi License Center. If you are a commercial user under maintenance, you should see your Gurobi 10 license under
Current Gurobi Licenses. If you would like to request a free academic license, you can do so from the
Free Academic License page. Once you have a license on the Gurobi web site, you will need to follow the instructions for installing a license in the
Quick Start Guide.
Supported Platforms for Version 10.0
*On Ubuntu 22.04 for x86-64, user code that calls dlopen()/dlclose() to load/unload libgurobi100.so is known to fail. We have investigated the issue, and unfortunately we have not yet found a workaround.
Additional Supported Platform Information
Gurobi 10.0 supports the following language/platform versions:
Release Notes for Version 10.0
In addition to performance enhancements, Gurobi 10.0 adds the following new features:
- Logistic General Constraint: Our existing general constraint feature allows you to add common higher-level constraints using a convenient shorthand. This release includes a new logistic constraint, which allows you to model the logistic function y = 1/(1+e^(-x)) on problem variables x and y. See the general constraint discussion in the Reference Manual for more information.
- Python API: With version 10.0 we have extended the capabilities of the modeling classes MVar, MLinExpr, and MQuadExpr, and improved their behaviour in many respects.
- Web License Service: The Gurobi Web License Service (WLS) previously only worked within containerized environments. With Gurobi 10.0, WLS licenses are also available that work outside of containers (on Windows, macOS and Linux), as well as in both types of environments.
- New Parameters and Attributes: In addition to the attributes and parameters directly tied to the new features above, there are four additional new parameters:
- NetworkAlg to control the network simplex algorithm.
- OBBT to control the aggressiveness of Optimality-Based Bound Tightening.
- SoftMemLimit to limit the total amount of memory available to an optimization, leading to a graceful exit when the limit is hit.
- WLSTokenRefresh to specify the relative refresh interval of a Web License Service token.
Code Conversion from Version 9.5
Programs that were originally written for version 9.5 of the Gurobi Optimizer typically won’t require any code changes to use version 10.0. If you’d like to use the new features, some code changes are required. We did remove a few deprecated attributes and methods, which may require code changes. Details are available in the
Detailed Release Notes.
