Description

Limits the number of passes for generating Gomory fractional cuts. At the default setting of 0 (zero), CPLEX decides the number of passes to make. The parameter is ignored if the Gomory fractional cut parameter (MIP Gomory fractional cuts switch: CPX_PARAM_FRACCUTS, FracCuts) is set to a nonzero value.
