PrePasses


PrePasses

Presolve pass limit
 Type: int
 Default value: -1
 Minimum value: -1
 Maximum value: MAXINT

Limits the number of passes performed by presolve. The default setting (-1) chooses the number of passes automatically. You should experiment with this parameter when you find that presolve is consuming a large fraction of total solve time.

One important note about integer-valued parameters: while the maximum value that can be stored in a signed integer is $2^{31}-1$, we use a MAXINT value of 2,000,000,000. Attempting to set an integer parameter to a value larger than this maximum will produce an error.

For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
