1. EEL 5937 Multi Agent Systems -an introduction-

2. EEL 5937 Content What is an agent? Communication Ontologies Mobility Mutability Applications

3. EEL 5937 What is an agent?

4. EEL 5937 Definition… An autonomous agent is a system situated within and part of an environment that senses that environment and acts on it, over time, in pursuit of its own agenda and so as to effect what it senses in the future. Franklin and Graesser: Is it an agent or just a program? Simpler: agents are autonomous programs

5. EEL 5937 Coming from AI… Expert systems did not prove commercially successful: too ambitious Agents provide a way to use limited amount of intelligence to achieve useful goals Russell & Norvig: Artificial Intelligence, a Modern Approach –Modern = Agent based

6. EEL 5937 Coming from OOP… Allows us to use more complex entities than traditional OOP Active components, not handled in OOP OOP definition of agent: object with a thread –Simplistic, but it can be used as a marketing term Software engineering techniques need to be updated

7. EEL 5937 Coming from Client-Server computing… Client originates requests, server responds The model is too simple, many times we need active components, e.g. for monitoring Enterprise Java Beans actively discourage beans with threads –They have their reasons, but limits functionality –There are workarounds but will need to be handled at the standards level

8. EEL 5937 People also come from: Business: –Agents seen as economic entities Sociology –Social models of agent –Agent models of the society Phychology: –Behavior patterns User Interaction Design Philosophy …Lots of sources of confusion.
