Global MINLP Optimality, Plus More Performance Improvements
With Gurobi 12.0, users can solve complex nonlinear problems to global optimality, and achieve superior performance across all mixed-integer optimizations thanks in part to more efficient use of CPU cores.
In addition, thread-based load balancing maximizes hardware utilization when running multiple jobs on our Compute Server and Cluster Manager, while our revamped documentation offers a more streamlined, user-friendly experience.
Performance Improvements
As with every major release, Gurobi continues to push the boundaries of solver performance. With Gurobi 12.0, users can expect the following speed-ups compared to the previous version:
| ALGORITHM | SPEED-UP Overall (>1 sec) |
SPEED-UP On Hard Models (>100sec) |
|---|---|---|
| LP (barrier) | 2.2% | 4.8% |
| LP (dual) | 4.4% | 3.6% |
| LP (primal) | 2.6% | 2.0% |
| MIP | 13.1% | 18.9% |
| MIQP | 13.0% | 38.3% |
| Nonconvex MIQCP | 27.7% | 68.5% |

New Features
In addition to performance enhancements, Gurobi 12.0 includes several exciting new features:
- Global MINLP Optimality – Directly state nonlinear constraints using Gurobi’s APIs and solve mixed-integer nonlinear programming (MINLP) problems to global optimality.
- Nonlinear Expressions in gurobipy – Easily model your mixed-integer nonlinear problems in our Python API.
- Memory Consumption Queries – Monitor memory consumption to assess memory requirements during development and prevent issues when running Gurobi on a shared server.
- Reduced Memory Footprint for Solution Storage – This makes it easier to store large solution pools.
“Gurobi 12.0 represents a significant step forward not only in speed, but also in usability. Today’s businesses face increasingly complex challenges—but as those challenges have evolved, so has our solver. With every major release, we’re able to help users address an even wider range of problems and make optimal, data-driven decisions.”
Chief Executive Officer, Gurobi
Gurobi Cluster Manager & Compute Server
- Thread-based Load Balancing – Leverage a finer granularity of control to maximize Compute Server utilization.
- Support for SetSolution in Callbacks – Now available for Compute Server runs, this feature allows you to provide feasible solution vectors during solving.
- Job Interruption – You can now interrupt running jobs from the management interface with full control of termination handling.
Documentation
- A New, Modern Look – Revamped documentation offers a streamlined, user-friendly experience.
- Continuous Deployment: Our new documentation is continuously updated and redeployed with the latest additions and corrections.
“Our new features improve the control and monitoring of computational resources. This helps ensure better performance, and makes Gurobi easier to use in large-scale, distributed environments.”
