AggFill


AggFill

Presolve aggregation fill level
Type: int
Default value: -1
Minimum value: -1
Maximum value: MAXINT

Controls the amount of fill allowed during presolve aggregation. Larger values generally lead to presolved models with fewer rows and columns, but with more constraint matrix non-zeros.

The default value chooses automatically, and usually works well.
