Constructor and Description |
---|
ExtensionalSupportMDD(IntVar[] vars,
int[][] table)
It constructs extensional support constraint.
|
ExtensionalSupportMDD(MDD diagram)
It creates an extensional constraint.
|
Modifier and Type | Method and Description |
---|---|
ArrayList<Var> |
arguments()
It returns the variables in a scope of the constraint.
|
void |
consistency(Store s)
It is a (most probably incomplete) consistency function which removes the
values from variables domains.
|
int |
getConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
constraint.
|
void |
impose(Store store)
It imposes the constraint in a given store.
|
void |
increaseWeight()
It increases the weight of the variables in the constraint scope.
|
void |
removeConstraint()
It removes the constraint by removing this constraint from all variables.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
boolean |
seekSupport(int nodeId,
int level)
It checks if the node at a given level of MDD has a support.
|
String |
toString()
It produces a string representation of a constraint state.
