Distributed learning in multi-armed bandit with multiple players
K Liu, Q Zhao - IEEE transactions on signal processing, 2010 - ieeexplore.ieee.org
We formulate and study a decentralized multi-armed bandit (MAB) problem. There are M
distributed players competing for N independent arms. Each arm, when played, offers iid …
