Frequency of the RINS heuristic. Default value (-1) chooses
automatically. A value of 0 shuts off RINS. A positive value
n applies RINS at every
n-th node of the MIP search
Increasing the frequency of the RINS heuristic shifts the focus of the MIP search away from proving optimality, and towards finding good feasible solutions. We recommend that you try MIPFocus, ImproveStartGap, or ImproveStartTime before experimenting with this parameter.
One important note about integer-valued parameters: while the maximum value that can be stored in a signed integer is , 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
