WebNevertheless, the Gittins index policy is important because, by splitting the optimization problem into Nindependent smaller subproblems, it reduces the problem dimension considerably. Moreover, at each stage only one arm changes its state, and so at most one index has to be re-evaluated. For those reasons, many WebSep 24, 2009 · For an M/G/1 queue with the objective of minimizing the mean number of jobs in the system, the Gittins index rule is known to be optimal among the set of non-anticipating policies.We develop properties of the Gittins index. For a single-class queue it is known that when the service time distribution is of type Decreasing Hazard Rate (New …

WebAbstract. This paper considers the multiarmed bandit problem and presents a new proof of the optimality of the Gittins index policy. The proof is intuitive and does not require an interchange argument. The insight it affords is used to give a streamlined summary of previous research and to prove a new result: The optimal value function is a ...

In the presence of model misspecification, numerical experiments show that the robust Gittins index policy not only outperforms the classical Gittins index policy, but also substantially reduces the variability in the out-of-sample performance.
