SubMIPNodes

Nodes explored in sub-MIP heuristics
 Type: int
 Default value: 500
 Minimum value: 0
 Maximum value: MAXINT

Limits the number of nodes explored by MIP-based heuristics (such as RINS). Exploring more nodes can produce better solutions, but it generally takes longer.

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.

Note: Only affects mixed integer programming (MIP) models
