Xiaomeng Zhu, Fengming Zhu, Weijie Zhou +8
While passive agents merely follow instructions, proactive agents align with higher-level objectives, such as assistance and safety by continuously monitoring the environment to de…
A Computable Game-Theoretic Framework for Multi-Agent Theory of Mind
Fengming Zhu, Yuxin Pan, Xiaomeng Zhu +1
Originating in psychology, (ToM) has attracted significant attention across multiple research communities, especially logic, economics, and robotics. Most…
Constant-Memory Strategies in Stochastic Games: Best Responses and Equilibria
Fengming Zhu, Fangzhen Lin
Stochastic games have become a prevalent framework for studying long-term multi-agent interactions, especially in the context of multi-agent reinforcement learning. In this work, w…
Single-Agent Planning in a Multi-Agent System: A Unified Framework for Type-Based Planners
Fengming Zhu, Fangzhen Lin
We consider a general problem where an agent is in a multi-agent environment and must plan for herself without any prior information about her opponents. At each moment, this pivot…
