PreDepRow

Controls the presolve dependent row reduction
 Type: int
 Default value: -1
 Minimum value: -1
 Maximum value: 1

Controls the presolve dependent row reduction, which eliminates linearly dependent constraints from the constraint matrix. The default setting (-1) applies the reduction to continuous models but not to MIP models. Setting 0 turns the reduction off for all models. Setting 1 turns it on for all models.
