WebWe call this strategy the Gittins index rule for multi-armed bandits with multiple plays, or briefly the Gittins index rule. We show by examples that: (i) the aforementioned … Websimpliﬁes computation and analysis, leading to multiarmed bandit policies that decompose the problem by arm. The landmark result of Gittins and Jones [2], assuming an inﬁnite horizon and discounted rewards, shows that an optimal policy always pulls the arm with the largest “index,” where indices can be computed independently for each arm.
