This function returns a constraint that states that whenever both interval variables a and b are present, the distance end(b)-start(a) between the start of interval a and the end of interval b must be greater than or equal to z. You must add this constraint to a model and extract the model to an algorithm in order for it to be taken into account.

Note: This constraint cannot be used in a logical constraint.

For more information on precedences between interval variables, see the concept Precedence constraints.
