  • Field Details

  • Constructor Details

    • ChannelImply

      public ChannelImply(IntVar x, IntVar[] bs, int[] value)
      It creates ChannelImply constraint.
      Parameters:
      x - variable to be checked.
      bs - array representing the status of equality x = i.
      value - array of values that are checked against x.
    • ChannelImply

      public ChannelImply(IntVar x, IntVar[] bs, IntDomain value)
      It creates ChannelImply constraint.
      Parameters:
      x - variable to be checked.
      bs - array representing the status of equality x = i.
      value - set of values that are checked against x.
    • ChannelImply

      public ChannelImply(IntVar x, IntVar[] bs)
    • ChannelImply

      public ChannelImply(IntVar x, Map<Integer,? extends IntVar> bs)
  • Method Details

    • toArray

      static int[] toArray(IntDomain d)
    • 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.
      Specified by:
      consistency in class Constraint
      Parameters:
      store - constraint store within which the constraint consistency is being checked.
    • swap

      private void swap(int i, int j)
    • getDefaultConsistencyPruningEvent

      public int getDefaultConsistencyPruningEvent()
      Specified by:
      getDefaultConsistencyPruningEvent in class Constraint
    • satisfied

      public boolean satisfied()
      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 interface SatisfiedPresent
      Returns:
      true if constraint is possible to verify that it is satisfied.
    • impose

      public void impose(Store store)
      Description copied from class: Constraint
      It imposes the constraint in a given store.
      Overrides:
      impose in class Constraint
      Parameters:
      store - the constraint store to which the constraint is imposed to.
    • toString

      public String toString()
      Description copied from class: Constraint
      It produces a string representation of a constraint state.
      Overrides:
      toString in class Constraint
