Macro CPXMIP_OPTIMAL_RELAXED_SUM

This status occurs only after a call to the Callable Library routine CPXfeasopt (or the Concert Technology method feasOpt) with the parameter CPX_PARAM_FEASOPTMODE (or FeasOptMode) set to CPX_FEASOPT_OPT_SUM (or OptSum) on a mixed integer model. A relaxation was successfully found and a feasible solution for the model (if relaxed according to that relaxation) was installed. The relaxation is optimal.
