  • Enum Constant Details

    • STRATIFICATION_NONE

      public static final SatParameters.MaxSatStratificationAlgorithm STRATIFICATION_NONE
       No stratification of the problem.
      STRATIFICATION_NONE = 0;

    • STRATIFICATION_DESCENT

      public static final SatParameters.MaxSatStratificationAlgorithm STRATIFICATION_DESCENT
       Start with literals with the highest weight, and when SAT, add the
 literals with the next highest weight and so on.
      STRATIFICATION_DESCENT = 1;

    • STRATIFICATION_ASCENT

      public static final SatParameters.MaxSatStratificationAlgorithm STRATIFICATION_ASCENT
       Start with all literals. Each time a core is found with a given minimum
 weight, do not consider literals with a lower weight for the next core
 computation. If the subproblem is SAT, do like in STRATIFICATION_DESCENT
 and just add the literals with the next highest weight.
      STRATIFICATION_ASCENT = 2;

      Returns:
      the enum constant with the specified name
      Throws:
      java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
      java.lang.NullPointerException - if the argument is null

    • getNumber

      public final int getNumber()
      Specified by:
      getNumber in interface com.google.protobuf.Internal.EnumLite

    • valueOf

      @Deprecated public static SatParameters.MaxSatStratificationAlgorithm valueOf​(int value)
      Deprecated.
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      value - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
      java.lang.NullPointerException - if the argument is null

    • forNumber

      public static SatParameters.MaxSatStratificationAlgorithm forNumber​(int value)
      Parameters:
      value - The numeric wire value of the corresponding enum entry.
      Returns:
      The enum associated with the given numeric wire value.
