PreMIQCPForm
Format of presolved MIQCP model
| Type: | int | |
|---|---|---|
| Default value: | -1 | |
| Minimum value: | -1 | |
| Maximum value: | 2 |
Determines the format of the presolved version of an MIQCP model. Option 0 leaves the model in MIQCP form, so the branch-and-cut algorithm will operate on a model with arbitrary quadratic constraints. Option 1 always transforms the model into MISOCP form; quadratic constraints are transformed into second-order cone constraints. Option 2 always transforms the model into disaggregated MISOCP form; quadratic constraints are transformed into rotated cone constraints, where each rotated cone contains two terms and involves only three variables.
The default setting (-1) choose automatically. The automatic setting works well, but there are cases where forcing a different form can be beneficial.
Note: Only affects MIQCP models
