3.7.197. Reified constraint
The reified version of a given constraint , where has as arguments all arguments of plus one extra 0-1 variable. This 0-1 variable is set to 1 when constraint holds, and 0 otherwise. Note that constraint inherits from all restrictions of constraint (i.e.,Β incorrect parameters for constraint are also incorrect for constraint ). Within the context of linear programming the extra 0-1 variable is often called an indicator variable.
