- Recap agents
	- what they denote
	- what they conceptualize

- Types of agents
        - rote agent (table-driven)
                - intelligence was primarily with
                  agent builder, not the agent
        - reflex agents (condition-action rules)
        - agents with internal state (a little bit of
          thinking goes on)
        - goal-based agents (have a sense of purpose)
        - utility-based agents (are calculative)

- Reading assignments
        - finish Chapter 1 and Chapter 2 (on your own)

        - search
                - AI "lifeline"
                - almost any AI problem can be formulated as
                  search
                - search compensates for lack of knowledge
        - knowledge representation and reasoning
                - knowledge compensates for lack of search
        - learning
                - emphasis on evaluation
        - reinforcement learning
                - learning without a teacher
                - in some ways, envelops AI itself
                - can be viewed as a restatement of the AI
                  problem
