TuneTrials

Perform multiple runs on each parameter set to limit the effect of random noise
 Type: int
 Default value: 3
 Minimum value: 1
 Maximum value: MAXINT

Performance on a MIP model can sometimes experience significant variations due to random effects. As a result, the tuning tool may return parameter sets that improve on the baseline only due to randomness. This parameter allows you to perform multiple solves for each parameter set, using different Seed values for each, in order to reduce the influence of randomness on the results.

One important note about integer-valued parameters: while the maximum value that can be stored in a signed integer is <span>$</span>2^{31}-1<span>$</span>, 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.

Note: Only affects mixed integer programming (MIP) models
