This function returns a constraint that states that the value of cumul function expression f should be always within the range [vmin,vmax] between start and end. Values vmin and vmax must be in range 0..IloIntervalMax. 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 cumul function expressions, see the concept Cumul functions in CP Optimizer.

This function returns a constraint that states that whenever interval variable a is present, the value of cumul function expression f should be always within the range [vmin,vmax] between the start and the end of a. Values vmin and vmax must be in range 0..IloIntervalMax. 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.

This function returns a constraint that ensures that, if it is defined, the value of state function f remains in the range [vmin,vmax] for any point t in the interval of integers [start,end).

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