Constructor Details

CumulativeOptional

public CumulativeOptional(IntVar[] starts,
 IntVar[] durations,
 IntVar[] resources,
 IntVar limit,
 IntVar[] opt)

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.

opt - variables informing whether the tasks is present or not.

CumulativeOptional

public CumulativeOptional(List<? extends IntVar> starts,
 List<? extends IntVar> durations,
 List<? extends IntVar> resources,
 IntVar limit,
 List<? extends IntVar> opt)

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.

opt - variables informing whether the tasks is present or not.

Method Details

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.

filterZeroTasks

TaskView[] filterZeroTasks(TaskView[] ts)

Overrides:

filterZeroTasks in class Cumulative

getDefaultConsistencyPruningEvent

public int getDefaultConsistencyPruningEvent()

Overrides:

getDefaultConsistencyPruningEvent in class Cumulative

toString

public String toString()

Description copied from class: Constraint

It produces a string representation of a constraint state.

Overrides:

toString in class Cumulative
