Cooperative and Competitive Biases for Multi-Agent Reinforcement Learning [PDF]
arXiv, 2021 Training a multi-agent reinforcement learning (MARL) algorithm is more challenging than training a single-agent reinforcement learning algorithm, because the result of a multi-agent task strongly depends on the complex interactions among agents and their interactions with a stochastic and dynamic environment.

Fact-based Agent modeling for Multi-Agent Reinforcement Learning [PDF]
arXiv, 2023 In multi-agent systems, agents need to interact and collaborate with other agents in environments. Agent modeling is crucial to facilitate agent interactions and make adaptive cooperation strategies. However, it is challenging for agents to model the beliefs, behaviors, and intentions of other agents in non-stationary environment where all agent ...
