Relaxation Induced Neighborhood Search (RINS) heuristic frequency
Type: int
Default value: -1
Minimum value: -1
Maximum value: MAXINT

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 tree.

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.

Note: Only affects mixed integer programming (MIP) models
