public class SumWeightedSet extends Constraint
Modifier and Type | Field and Description |
---|---|
SetVar |
a
A set variable a whose elements contribute with their weight to the sum.
|
int[] |
elements
It specifies the list of allowed elements and helps to connect the weight
to the element.
|
IntVar |
totalWeight
Integer variable containing the total weight of all elements within a set variable a.
|
int[] |
weights
It specifies a weight for every element of the allowed element in the
domain of set variable a.
|
static String[] |
xmlAttributes
It specifies the arguments required to be saved by an XML format as well as
the constructor being called to recreate an object from an XML format.

Constructor and Description |
---|
SumWeightedSet(SetVar a,
int[] elements,
int[] weights,
IntVar totalWeight)
It constructs a weighted set sum constraint.
|
SumWeightedSet(SetVar a,
int[] weights,
IntVar totalWeight)
It constructs a weighted set sum constraint.
|
SumWeightedSet(SetVar a,
IntVar totalWeight)
It constructs a weighted set sum constraint.
|
Modifier and Type | Method and Description |
---|---|
ArrayList<Var> |
arguments()
It returns the variables in a scope of the constraint.
|
void |
consistency(Store store)
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.
|
String |
id()
It gives the id string of a 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.
|
String |
toString()
It produces a string representation of a constraint state.
