Refined Algorithms for Infinitely Many-Armed Bandits with Deterministic Rewards

We consider a variant of the Multi-Armed Bandit problem which involves a large pool of a priori identical arms (or items). Each arm is associated with a deterministic value, which is sampled from a probability distribution with unknown maximal value, and is revealed once that arm is chosen. At each time instant the agent may choose a new arm (with unknown value), or a previously-chosen arm whos...

Decades of effort to understand intracellular move...

Those who conduct foreign policy often dismiss academic theorists (frequently, one must admit, with good reason), but there is an inescapable link between the abstract world of theory and the real world of policy.
