public class Binpacking extends Constraint
| Modifier and Type | Field and Description |
|---|---|
org.jacop.constraints.binpacking.BinItem[] |
item
It keeps together a list of variables which define bin for item i and
their weigts.
|
IntVar[] |
load
It specifies a list of variables which define bin load.
|
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.

|---|
Binpacking(ArrayList<? extends IntVar> bin,
ArrayList<? extends IntVar> load,
int[] w)
It constructs the binpacking constraint for the supplied variable.
|
Binpacking(IntVar[] bin,
IntVar[] load,
int[] w)
It constructs the binpacking constraint for the supplied variable.
|
| 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.
|
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 |
queueVariable(int level,
Var V)
This is a function called to indicate which variable in a scope of
constraint has changed.
|
void |
removeConstraint()
It removes the constraint by removing this constraint from all variables.
|
void |
removeLevel(int level)
This function is called in case of the backtrack, so a constraint can
clear the queue of changed variables which is no longer valid.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
