Field Detail

limit

public final IntVar limit

It specifies the limit of the profile of cumulative use of resources.

Constructor Detail

CumulativeBasic

public CumulativeBasic(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.

CumulativeBasic

public CumulativeBasic(List<? extends IntVar> starts,
                       List<? extends IntVar> durations,
                       List<? extends 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.

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.

Specified by:

consistency in class Constraint

Parameters:

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

getDefaultConsistencyPruningEvent

public int getDefaultConsistencyPruningEvent()

Specified by:

getDefaultConsistencyPruningEvent in class Constraint

toString

public String toString()

Description copied from class: Constraint

It produces a string representation of a constraint state.

Overrides:
