3. MAS course: objectives / content MAS course Software Engineering using Multi-Agent Systems  situate MAS in “mainstream software engineering” mostly distributed software engineering just a few topics in this course, and even then, just fragments of these topics  general perspective  typical agent architectures  interaction  communication  ant-like systems  …  “Agents are 99% computer science, and 1% A.I.” (Etzioni)

4. MAS course: objectives / content After this course, you should be able to…  Situate multi-agent systems in a software engineering perspective  Judging the usefulness of a multi-agent system for distributed problem solving  Make well-founded decisions in defining multi-agent system software architectures, including Agents Agent behavior architecture Coordination schemes  Message-based vs. envrironment-centric coordination taking into account non-functional requirements of scalability, flexibility, adaptability

5. MAS prerequisites object-oriented programming exercises terminology software development basic terminology of distributed systems / AI helps: software engineering in general  UP, requirements, analysis, OOD, design patterns

6. MAS: classes, exercises, practical work officially: 19.5 hourslectures 10 hoursexercise sessions planning in practice: +- 7 lectures (1.5h)  “theory”  discussion 4 exercise sessions (2.5h)  PC lab sessions  Robrecht Haesevoets (Robrecht.Haesevoets@cs.kuleuven.be)
