With our powerful algorithms, you can add complexity to your model to better represent the real world, and still solve your model within the available time.

  • The performance gap grows as model size and difficulty increase.
  • Gurobi has a history of making continual improvements across a range of problem types, with a 91x speedup on MILP since version 1.1.
  • Gurobi is tuned to optimize performance over a wide range of instances.
  • Gurobi is tested thoroughly for numerical stability and correctness using an internal library of over 10,000 models from industry and academia.

The Gurobi R&D team continually pushes the boundaries of performance. With each new version, Gurobi enables users to solve even more models, even faster, and solve models that were previously intractable.
 

MILP Performance Evolution

In Gurobi’s MILP benchmark suite, the latest version delivers:

  • a 91x speed-up over version 1.1 in geometric mean (PAR-10) of runtimes.
  • Only 197 models remain unsolved after 10,000 seconds with the latest version. The test set consists of all models that can be solved by at least one version.


Time limit: 10000 sec. Intel Xeon CPU E3-1240 v5 @ 3.50GHz
4 cores, 8 hyper-threads
32 gb ram

Test set has 8273 models:
– 788 discarded due to inconsistent answers
– 2286 discarded due that none of the versions can solve
– speed-up measured on > 100s bracket: 3076 models

 
 

Nonconvex MIQCP Performance Evolution

In Gurobi’s MIQCP benchmark suite, the latest version delivers:
