```
public final HyperParameterTuningJobStrategyType strategy()
```
    Specifies how hyperparameter tuning chooses the combinations of hyperparameter values to use for the training job it launches. For information about search strategies, see How Hyperparameter Tuning Works.
    
    If the service returns an enum value that is not available in the current SDK version, strategy will return HyperParameterTuningJobStrategyType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from strategyAsString().

  - trainingJobEarlyStoppingType
```
public final TrainingJobEarlyStoppingType trainingJobEarlyStoppingType()
```
    Specifies whether to use early stopping for training jobs launched by the hyperparameter tuning job. Because the Hyperband strategy has its own advanced internal early stopping mechanism, TrainingJobEarlyStoppingType must be OFF to use Hyperband. This parameter can take on one of the following values (the default value is OFF):
    
    OFF
    
    Training jobs launched by the hyperparameter tuning job do not use early stopping.
    
    AUTO
    
    SageMaker stops training jobs launched by the hyperparameter tuning job when they are unlikely to perform better than previously completed training jobs. For more information, see Stop Training Jobs Early.
    
    If the service returns an enum value that is not available in the current SDK version, trainingJobEarlyStoppingType will return TrainingJobEarlyStoppingType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from trainingJobEarlyStoppingTypeAsString().
    
    Returns:
