Multiarmed bandit(MAB) models are widely used for sequential decision-making in uncertain environments, such as resource allocation in computer communication systems.A critical challenge in interactive multiagent systems with bandit feedback is to explore and understand the equilibrium state to ensure stable and tractable system performance. Markov games are commonly used to track state evolution and derive learning equilibria with continuous rewards but struggle to scale effectively as the number of agents increases [1].
