1439 Line %lld: Illegal indicator constraint
#define CPXERR_BAD_INDCONSTR 1439
Indicator constraints are not allowed in the objective,
nor in lazy constraints, nor in user cuts sections. The indicator variable
may only be compared against values of 0 (zero) and 1 (one).
The MPS format requires that the indicator type be "IF" and that
indicator constraints be of type 'E', 'L', or 'G'.
