Presentation Transcript

  1. Many systems function via cooperation between subunits Without centralised control and enforcement When subunits act “selfishly” for their own ends When subunits sometimes have conflicting goals Examples include (aspects of): Biological systems Human social systems Increasingly: distributed information systems Basic questions: What kinds of theories, tools and analysis can help us to understand and engineer cooperation Specifically, can bio- and socio-inspired ideas be imported into engineering practice? What’s it all about?

  2. Convergence between open problems in: Distributed information systems Biological and social sciences Convergence in techniques: Complex Systems viewpoint Computer simulation (agent-based) Evolutionary approaches Increase emphasis on: Non-equilibrium analysis Bounded rather than classical rationality Local interactions -> emergent global properties Self-Organisation Why now?

  3. Increasing need for robust, self-organising, cooperative behaviour over unreliable and non-centralised infrastructures such as the Internet. New technologies widely deployed and used: P2P (BitTorrent, Skype, edonkey) Grid Systems Mobile ad hoc wireless networks Understanding how to “engineer” self-organising cooperative systems is now a “hot topic” But is it a passing fad? Distributed Information Systems

  4. Many workshops and conferences list this issue as a topic of interest in their long lists of topics but: The bio- and socio- orientated community tend to focus on highly general models (simple topologies, games, replicator dynamics) The distributed systems community tend to focus on specific application areas (non-general, poor theory, ah hoc) Here we wish to focus on both general approaches / theory but also (with an eye to) applications The “Holy Grail” would be highly general theories applicable to many specific applications What’s different?

  5. Foster collaboration and cooperation between different groups It is highly likely that this area will be directly addressed by various future European funding initiatives (FP7 IST) => possible future consortia Many here are PhD students working in similar areas => highly useful to make contact Have fun Drink wine Other Goals

  6. Today: General cooperation in selfish systems approaches PhD student session (@5:30pm) Tomorrow: More specific “tag” inspired approaches “Tagworld 1” Work in progress session after lunch (@3pm) Open problems and challenges session (@4pm) Outline Schedule

  7. A message from our sponsors http://delis.upb.de/ http://www.cs.unibo.it/bici

  8. The End
