Global cut generation control. The following settings apply to all the cut generation parameters.
| Automatic (-1) | GUROBI decides. |
| No Cuts (0) | No cut generation is performed. |
| conservative Cuts (1) | Conservative Cut generation. |
| Aggressive Cuts (2) | Aggressive Cut generation. |

A non-negative value indicates the maximum number of Gomory cut passes performed. Overrides the Cut level parameter.
A non-negative value indicates the maximum number of constraint aggregation passes performed during cut generation. Overrides the Cut level parameter.
A non-negative value indicates the maximum number of cutting planes passes performed during root cut generation. The default value chooses the number automatically.
