Update the controller with evaluation result of a neural architecture.

        Parameters
        ----------
        other_info: any object
            In our case it is the father ID in the search tree.
        graph: Graph
            An instance of Graph. The trained neural architecture.
        metric_value: float
            The final evaluated metric value.
        model_id: int
