In probability theory and machine learning, the multi-armed bandit problem (sometimes called the K- or N-armed bandit problem ) is a problem in which a fixed limited set of resources must be allocated between competing (alternative) choices in a way that maximizes their expected gain, when … See more The multi-armed bandit problem models an agent that simultaneously attempts to acquire new knowledge (called "exploration") and optimize their decisions based on existing knowledge (called "exploitation"). The … See more A major breakthrough was the construction of optimal population selection strategies, or policies (that possess uniformly maximum convergence rate to the … See more Another variant of the multi-armed bandit problem is called the adversarial bandit, first introduced by Auer and Cesa-Bianchi (1998).
