Linear
public Linear(Store store, IntVar[] list, int[] weights, java.lang.String rel, int sum)
Deprecated.It constructs the constraint Linear.- Parameters:
store
- current storelist
- variables which are being multiplied by weights.weights
- weight for each variable.rel
- the relation, one of "==", "<", ">", "<=", ">=", "!="sum
- variable containing the sum of weighted variables.
-
Linear
public Linear(Store store, java.util.List<? extends IntVar> variables, java.util.List<java.lang.Integer> weights, java.lang.String rel, int sum)
Deprecated.It constructs the constraint Linear.- Parameters:
store
- current storevariables
- variables which are being multiplied by weights.weights
- weight for each variable.rel
- the relation, one of "==", "<", ">", "<=", ">=", "!="sum
- variable containing the sum of weighted variables.

Method Detail

removeLevelLate
public void removeLevelLate(int level)
Deprecated.Description copied from interface:RemoveLevelLate
This function is called in case of the backtrack. It is called after all timestamps, variables, mutablevariables have reverted to their values *after* removing the level.- Specified by:
removeLevelLate
in interfaceRemoveLevelLate
- Parameters:
level
- the level which is being removed.
-
consistency
public void consistency(Store store)
Deprecated.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 classConstraint
- Parameters:
store
- constraint store within which the constraint consistency is being checked.
-
pruneRelation
private void pruneRelation(Store store, byte rel)
Deprecated.
-
getDefaultConsistencyPruningEvent
public int getDefaultConsistencyPruningEvent()
Deprecated.- Specified by:
getDefaultConsistencyPruningEvent
in classConstraint
-
impose
public void impose(Store store)
Deprecated.Description copied from class:Constraint
It imposes the constraint in a given store.- Overrides:
impose
in classConstraint
- Parameters:
store
- the constraint store to which the constraint is imposed to.
-
queueVariable
public void queueVariable(int level, Var var)
Deprecated.Description copied from class:Constraint
This is a function called to indicate which variable in a scope of constraint has changed. It also indicates a store level at which the change has occurred.- Overrides:
queueVariable
in classConstraint
- Parameters:
level
- the level of the store at which the change has occurred.var
- variable which has changed.
-
satisfied
public boolean satisfied()
Deprecated.Description copied from interface:SatisfiedPresent
It checks if the constraint is satisfied. It can return false even if constraint is satisfied but not all variables in its scope are grounded. It needs to return true if all variables in its scope are grounded and constraint is satisfied.Implementations of this interface for constraints that are not PrimitiveConstraint may require constraint imposition and consistency check as a requirement to work correctly.
- Specified by:
satisfied
in interfaceSatisfiedPresent
- Returns:
- true if constraint is possible to verify that it is satisfied.
-
entailed
private boolean entailed(byte rel)
Deprecated.

recomputeBounds
void recomputeBounds()
Deprecated.
-
checkForOverflow
void checkForOverflow()
Deprecated.

relation
public byte relation(java.lang.String r)
Deprecated.
-
rel2String
public java.lang.String rel2String()
Deprecated.
-
toString
public java.lang.String toString()
Deprecated.Description copied from class:Constraint
It produces a string representation of a constraint state.- Overrides:
toString
in classConstraint
