  Given a problem description, alternate between a step in which a solution strategy is generated, and a step in which the solution strategy is evaluated and useful feedback is provided.

        Consider the original problem statement, the last proposed solution and the provided feedback. Does the solution need to be updated? If so, provide the corrected version of the conceptual solution in the following format:
        # Conceptual solution
        {{plan_placeholder}}
        otherwise, reply:
        "Final answer."
