Remarkably it turns out … WebWe investigate the general multi-armed bandit problem with multiple servers. We determine a condition on the reward processes sufficient to guarantee the optimality of the strategy that operates at each instant of time the projects with the highest Gittins indices.

WebWe provide a short and elementary proof of the Gittins index theorem for the multi-armed bandit problem, for the case where each bandit is modeled as a finite-state semi-Markov process. We also indicate how this proof can be extended to the branching bandits and Klimov problems. Citation Download Citation John N. Tsitsiklis.

WebA BSTRACT . We consider a version of the continuous-time multi-armed bandit problem where decision opportunities arrive at Poisson arrival times, and study its Gittins index policy. When driven by spectrally one-sided L´evy processes, the Gittins index can be written explicitly in terms of the scale function
WebThe Bayesian multi-armed bandit problem can be mod-eled as a Markov Decision Process (MDP). The state in this MDP represents the sufficient statistic of the history of the observed rewards for each arm. We denote the state space of the MDP that represents the multi-armed bandit problem as S= S 1 [S 2 [:::[S T, where S t is the set of states at ... day lewis north streetWebMulti-Armed Bandits, Gittins Index, and Its Calculation Jhelum Chakravorty and Aditya Mahajan 24 24.1 Introduction Multi-armed bandit is a colorful term that refers to the dilemma faced by a gambler playing in a casino with multiple slot ma-chines (which were colloquially called one-armed bandits).
