Symmetry


Symmetry

Symmetry detection
 Type: int
 Default value: -1
 Minimum value: -1
 Maximum value: 2

Controls symmetry detection. A value of -1 corresponds to an automatic setting. Other options are off (0), conservative (1), or aggressive (2).

Symmetry can impact a number of different parts of the algorithm, including presolve, the MIP tree search, and the LP solution process. Default settings are quite effective, so changing the value of this parameter rarely produces a significant benefit.
