CPXMI_OPT_TOL

1044 Detected objective coefficient <= the value of CPX_PARAM_EPOPT at %s

#define CPXMI_OPT_TOL 1044
The absolute value of the objective coefficient at the specified variable is less than or equal to the parameter optimality tolerance (included by cplex.h or cplexx.h). This situation can be a potential source of ill-conditioning or numerical instability in a model.
