These operators create a new IloPredicate<IloObject> instance by comparing the value returned by an evaluator with either that of another evaluator or a threshold value. The semantics of the new predicate is a less-than comparison. The first function creates a predicate which returns IloTrue if and only if the value returned by the left evaluator is less than the value returned by the right evaluator. The second function creates a predicate which returns IloTrue if and only if the value returned by the left evaluator is less than the threshold value. The third function creates a predicate that returns IloTrue if and only if the threshold value is less than the value returned by the right evaluator.

This operator compares its arguments; if the first argument is strictly less than the second, then it returns IlcTrue; otherwise, it returns IlcFalse.

This overloaded C++ operator constrains its first argument to be strictly less than its second argument. In order to be taken into account, this constraint must be added to a model and extracted for an algorithm.

This operator creates and returns an inequality constraint between its arguments (that is, the first must be strictly less than the second).

When its arguments are integer expressions, then when you post it, this constraint is associated with the whenRange propagation event.

When you create a constraint, it has no effect until you post it.
