IEEE Paper, 18 Apr 05

Agenda

• Discuss papers we came up with last time
• Add new papers to the list that we think we should read
  • Include papers from ACC 2005
• Discuss common themes
• Set agenda for next meeting

Discussion of papers

Viscek

This is the paper that Ali cites and so everyone cites it. In the physics community, this is cited correctly. In controls, this paper is often credited with things that aren't really in the paper. Deals with alignment in flocking behavior.

Position of agenda matters (who are your neighbors). Uses a completely nonlinear protocol as his alignment rule. Agents move with velocity v in the plane. Looks at effects of change in density and change in noise.

Some further work on crowd control (published in Nature) using similar tools (purely computational).

Takeaways for our paper

• Early example of a protocol
• Focused on alignment (common problem)

Related papers

• Jadbabaie
• Blondel et al (incorrect citation?)

Tabuada

Currently at Notre Dame. Alex cited this in this thesis. Was done in the context of nonholonomic vehicle. What graphs would you set up to enable meaningful controls. Started with acyclic graphs. Paper was never accepted into a journal.

Takeaways for our paper

• Might not cite this; Action (Demetri): look for follow up work (if any). If we can't find something more recent that is significant, probably won't include
• Effects of dynamics (especially nonlinear)

Related papers

• Naomi Leonard
• Action (Richard): look for other papers on this topic

Moreau

• Admits nonlinear update laws
• Makes use of properties of stochastic matrices

Common themes

"Protocols" for concensus and cooperation

• Distributed setting (doesn't require complete connectivity)

Agenda for next meeting

Original plan:

• List tools
• Open problems
• Outline paper

Revised plan:
