The Gurobi Optimizer is a commercial optimization solver for linear programming (LP), quadratic programming (QP), quadratically constrained programming (QCP), mixed integer linear programming (MILP), mixed-integer quadratic programming (MIQP), and mixed-integer quadratically constrained programming (MIQCP).

Gurobi is named for its founders: Zonghao Gu, Edward Rothberg and Robert Bixby. Bixby was also the founder of CPLEX, while Rothberg and Gu led the CPLEX development team for nearly a decade.[2]


The Gurobi Optimizer supports a variety of programming and modeling languages including:[3]

The Gurobi Optimizer also includes a number of features to support the building of optimization models including support for:[4]

  • Multiple objectives with flexibility in how they are prioritized
  • General constraints such as MIN/MAX, ABS, AND/OR, and indicator constraints help avoid having to turn commonly occurring constraints in linear constraints
  • Models with convex, piecewise-linear objective functions, to capture certain non-linear problems
  • Arbitrary piecewise-linear objective functions, to make it easier to express this common modeling feature
  • Distributed tuning, to speed the exploration of parameter settings to speed solve times

The Gurobi Optimizer also has options to deploy on the cloud [5] and for client-server computing [6]
