Cutting plane passes
  Type: int
  Default value: -1
  Minimum value: -1
  Maximum value: MAXINT

A non-negative value indicates the maximum number of cutting plane passes performed during root cut generation. The default value chooses the number of cut passes automatically.

In addition to cutting plane separation, each cut pass also applies heuristicsand node probing and also may launch parallel root helper threads. So even when the Cuts parameter is set to 0, the cut loop will apply probing, heuristics and parallel root helpers in a single cut loop iteration.

You should experiment with different values of this parameter if you notice the MIP solver spending significant time on root cut passes that have little impact on the objective bound.

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
