CumulativeUnary

public CumulativeUnary(IntVar[] starts,
                       IntVar[] durations,
                       IntVar[] resources,
                       IntVar limit)

It creates a cumulative constraint.

Parameters:

starts - variables denoting starts of the tasks.

durations - variables denoting durations of the tasks.

resources - variables denoting resource usage of the tasks.

limit - the overall limit of resources which has to be used.

CumulativeUnary

public CumulativeUnary(IntVar[] starts,

Method Detail

consistency

public void consistency(Store store)

Description copied from class: Constraint

It is a (most probably incomplete) consistency function which removes the values from variables domains. Only values which do not have any support in a solution space are removed.

Overrides:

consistency in class Cumulative

Parameters:

store - constraint store within which the constraint consistency is being checked.

toString

public String toString()

Description copied from class: Constraint

It produces a string representation of a constraint state.

Overrides:

toString in class Cumulative
