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. WebDownloadable! We generalise classical multiarmed bandits to allow for the distribution of a (fixed amount of a) divisible resource among the constituent bandits at each decision point. Bandit activation consumes amounts of the available resource, which may vary by bandit and state. Any collection of bandits may be activated at any decision epoch, provided …
