Highly restricted distributed systems - the example of opinion dynamics

Several man-made distributed systems, like mobile sensor nodes, and natural distributed systems, like bird flocks, can be modeled by agents whose communication or computational capabilities are severely limited.

I will start with a brief overview on problems I have been and am currently looking at within this domain, ranging from VLSI systems to the Physarum slime mold.

The main part of the talk will then detail on a prominent example from opinion dynamics: so called Hegselmann-Krause (HK) systems. Although its update rules are deceptively simple, many fundamental questions are still open today. I will give an introduction into the state of the art about HK, discuss different proof techniques, and show effective bounds on agent stabilization time. The talk concludes with a list of open problems.
