Description
Sets the amount of probing on variables to be performed before MIP branching. Higher settings perform more probing. Probing can be very powerful but very time-consuming at the start. Setting the parameter to values above the default of 0 (automatic) can result in dramatic reductions or dramatic increases in solution time, depending on the model.
