  3. TDDC65 during period 1 Lab 1 Introduction, formal notation, architectures Lab 2a intelligent agent software Lab 2b decision trees, causal nets Lab 2c Lab 3a decision trees etc resolution planning Lab 3b SAT or more planning

  4. Today's lecture • Discuss lab 2b • Architectures (BDI, HTN, other) • Message-passing between agents

  5. Today's lecture • Chapters in "Software for intelligent agents": • Discuss lab 2b • Architectures (BDI, HTN, other): Chapter 1 and 2 • Message-passing between agents: Chapter 6 • Chapters 3 and 4 already covered + self reading • Chapters 5 and 7 just outline • Chapter 8 during next period

  6. Belief, Desire, Intention Architecture • Use the text in the compendium

  7. Lab 2b: Simple Plan Execution System • Refer to the lab as an example of a simple plan execution system, implementing the execute operation in the BDI top-level loop

  8. Hierarchical Task Networks • Refer to the compendium chapter on HTN

  9. Message-Passing between Agents • Basis: Speech Act Theory, especially according to Searle • Knowledge Query and Manipulation Language (KQML) • Agent Communication Language (FIPA-ACL)
