    :: DeveloperApi :: Override this method to further optimize the process that runs multiple evaluations (during tuning, for example).

    :: DeveloperApi :: Override this method to further optimize the process that runs multiple evaluations (during tuning, for example). By default, this method calls eval for each element in the engine parameters list.

    sc

    An instance of SparkContext.

    engineParamsList

    A list of EngineParams for running batch evaluation.

    params

    An instance of WorkflowParams that controls the workflow.

    returns

    A list of engine parameters and evaluation result (from eval) tuples.
