Diversity of Logical Agents in Games Johan van Benthem, Fenrong Liu Abstract: Logical agents are usually taken to be epistemically perfect, but real agents may have various imperfections, in particular, due to bounded memory. This paper is a brief exploration of how different types of agents can be described in logical terms, how they update their information, and how they can even co-exist inside the same logical system. Keywords: dynamic-epistemic logic, bounded agents, product update, belief revision, games
