Approaches to Agent Design (continued)

• Goal-Based Agent
  • Choose actions so as to achieve a (given or computed) goal= a description of a desirable situation
  • Keeping track of the current state is often not enough--- need to add goals to decide which situations are good
  • Deliberative instead of reactive
  • May have to consider long sequences of possible actions before deciding if goal is achieved--- involves consideration of the future, "what will happen if I do...?"
