Social norms are powerful formalism in coordinating autonomous agents' behaviour to achieve certain objectives. In this paper, we propose a dynamic normative system to enable the reasoning of the changes of norms under different circumstances, which cannot be done in the existing static normative systems. We study two important problems (norm synthesis and norm recognition) related to the autonomy of the entire system and the agents, and characterise the computational complexities of solving these problems.

多智能体强化学习(MARL)算法经常遭受指数样本复杂度对智能体数量的依赖,这种现象被称为\emph{the curse of multiagents}。在本文中,我们解决这一挑战,调查样本效率的无模型算法在\emph{decentralized} MARL,并旨在改善现有的算法沿这条线。对于学习(粗)一般和马尔可夫博弈中的相关均衡,我们提出了\emph{stage-based} V-学习算法,大大简化了最近的作品的算法设计和分析,并规避了一个相当复杂的无\emph{weighted}遗憾强盗子程序。针对马尔可夫势博弈中纳什均衡的学习问题,提出了一种独立的策略梯度算法,该算法采用分散的基于动量的方差缩减技术。我们所有的算法都是去中心化的,因为每个代理只能根据其本地信息做出决策。在学习过程中既不需要通信,也不需要集中协调,从而导致对大量代理的自然泛化。我们还提供了数值模拟来证实我们的理论研究结果。
