In terms of performance tuning, there are three types of parameters:
- termination criteria,
- tolerance values, and
- algorithm behavior.
For termination criteria (ex: MIPGap) or tolerance values (ex: IntFeasTol), Gurobi parameters should correspond closely to those from other solvers.
However, in terms of algorithm behavior, it's generally best to start with default values, since default values in Gurobi have been tested to be fast and robust across a wide variety of models. See the Parameters table in the Reference Manual as well as the Parameter Guidelines section that follows immediately afterwards.
