Before revision:  We showcase asymptotic optimality and finite-sample upper bounds on the regret of the  proposed design mechanism . Simulations illustrate the advantage of the method over state-of-art methodologies  .
After revision:  We showcase asymptotic optimality and finite-sample upper bounds on the regret of the proposed design mechanism and regret guarantees of the proposed method. Finally we illustrate the advantage of the method over state-of-art methodologies .
