Restless multi-armed bandit

WebSep 1, 2024 · Hence, the multiuser restless multi-armed bandit can be used to formulate the problem of dynamic spectrum access in the real world, where arms of a slot-machine are assumed to be channels of the network. In RMAB, arms are restless, i.e. state of arms is kept on transiting irrespective of any action.

WebAbstract: In the classic Bayesian restless multi-armed bandit (RMAB) problem, there are N arms, with rewards on all arms evolving at each time as Markov chains with known parameters. A player seeks to activate K ≥ 1 arms at each time in order to maximize the expected total reward obtained over multiple plays. RMAB is a challenging problem that is … WebThis book is an adaptation of Western Civilization: A Concise History, volumes 2 and 3, written by Christopher Brooks.

WebarXiv May 7, 2024. This paper studies the problem of finding an anomalous arm in a multi-armed bandit when (a) each arm is a finite-state Markov process, and (b) the arms are restless. Here, anomaly means that the transition probability matrix (TPM) of one of the arms (the odd arm) is different from the common TPM of each of the non-odd arms. WebOur approach, namely MOEA/DRMAB, is a multi-objective selection hyper-heuristic that expands the MOEA/D framework. It uses an innovative Restless Multi- Armed Bandit (MAB) to determine the low level heuristic (Differential Evolution mutation strategy) that should be applied to each individual during a MOEA/D execution.

WebJun 16, 2013 · We define a general framework for a large class of combinatorial multi-armed bandit (CMAB) problems, where simple arms with unknown distributions form super arms.In each round, a super arm is played and the outcomes of its related simple arms are observed, which helps the selection of super arms in future rounds. WebThe Multi-Armed Bandit (MAB) problem has been extensively studied in order to address real-world challenges related to sequential decision making. In this setting, an agent selects the best action to be performed at time-step t, based on the past rewards received by the environment. This formulation implicitly assumes that the expected payoff for each action …
