Class SinPeqR

All Implemented Interfaces:
SatisfiedPresent, Stateful
Direct Known Subclasses:
AsinPeqR

public class SinPeqR extends Constraint implements Stateful, SatisfiedPresent
Constraints sin(P) = R

Bounds consistency can be used; third parameter of constructor controls this.

  • Method Details

    • removeLevel

      public void removeLevel(int level)
      Description copied from interface: Stateful
      This function is called in case of the backtrack, so a constraint can clear the queue of changed variables which is no longer valid. This function is called *before* all timestamps, variables, mutablevariables have reverted to their previous value.
      Specified by:
      removeLevel in interface Stateful
      Parameters:
      level - the level which is being removed.
    • 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.
    • boundConsistency

      void boundConsistency(Store store)
    • normalize

      FloatInterval normalize(FloatVar v)
    • intervalNo

      int intervalNo(double d)
    • 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.
    • toString

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

      public FloatVar derivative(Store store, FloatVar f, Set<FloatVar> vars, FloatVar x)
      Overrides:
      derivative in class DecomposedConstraint<Constraint>
