Abstract

For agents to behave successfully, they often need to reason about what they know and do not know about the world. For example, an agent may choose a particular sensing action only after it realizes that it is missing an important piece of information. From a knowledge representation point of view, the idea would be to supply the agent with a suitable knowledge base (KB) and provide it with an appropriate mechanism to query the KB. In order to get a glimpse of the complexity of the kinds of queries that might arise when actions are involved, let us consider the following example.
