Class Min

All Implemented Interfaces:
SatisfiedPresent

public class Min extends Constraint implements SatisfiedPresent
Min constraint implements the minimum/2 constraint. It provides the minimum varable from all FD varaibles on the list.
Version:
4.10
  • Field Details

    • idNumber

      static AtomicInteger idNumber
    • list

      public FloatVar[] list
      It specifies a list of variables among which the minimum value is being searched for.
    • min

      public FloatVar min
      It specifies variable min, which stores the minimum value within the whole list.
  • Constructor Details

    • Min

      public Min(FloatVar[] list, FloatVar min)
      It constructs min constraint.
      Parameters:
      list - the array of variables for which the minimal value is imposed.
      min - variable denoting the minimal value
    • Min

      public Min(List<? extends FloatVar> list, FloatVar min)
      It constructs min constraint.
      Parameters:
      list - the array of variables for which the minimal value is imposed.
      min - variable denoting the minimal value
  • Method Details

    • 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.
    • 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
