Controls model scaling. By default, the rows and columns of the model
are scaled in order to improve the numerical properties of the
constraint matrix. The scaling is removed before the final solution
is returned. Scaling typically reduces solution times, but it may
lead to larger constraint violations in the original, unscaled model.
Turning off scaling (
ScaleFlag=0) can sometimes produce smaller
constraint violations. Choosing a different scaling option
can sometimes improve performance for
particularly numerically difficult models.
