Enum SatParameters.Polarity

java.lang.Object
java.lang.Enum<SatParameters.Polarity>
com.google.ortools.sat.SatParameters.Polarity
All Implemented Interfaces:
com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, Serializable, Comparable<SatParameters.Polarity>, java.lang.constant.Constable
Enclosing class:
SatParameters
public static enum SatParameters.Polarity extends Enum<SatParameters.Polarity> implements com.google.protobuf.ProtocolMessageEnum
 Specifies the initial polarity (true/false) when the solver branches on a
 variable. This can be modified later by the user, or the phase saving
 heuristic.

 Note(user): POLARITY_FALSE is usually a good choice because of the
 "natural" way to express a linear boolean problem.

      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • valueOf

      @Deprecated public static SatParameters.Polarity 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:

      NullPointerException - if the argument is null

    • forNumber

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