Complexity and Criticality

Darlington Old School

Complexity, Criticality and Computation, C3-Summer 2015

This is the first in a series of planned workshop-style meetings aimed at exploring the common ground between complexity, criticality, and computation. Complex systems, such as modern power grids, communication and transport systems, social and eco-systems, and so on, generate rich interactions among components with non-trivial information flows, and exhibit critical phenomena, characterised by phase transitions. Cascading power failures, traffic disruptions, epidemic outbreaks, financial market crashes, avalanches in granular media, and ecosystem collapses are all manifestations of these challenges. Crucially, the many constituent microscopic parts bring about macroscopic phenomena that cannot be understood by considering a single part alone.


We intend to consider a diverse range of systems, applications, theoretical and practical approaches to computational modelling modern complex systems, including information theory, agent-based simulation, network theory, molecular dynamics, swarm intelligence, human-robotic interactions, computation theory, and econophysics, among others.


Our first workshop will be held at the Old Darlington School, the University of Sydney - a very nice historic building, close to Peter Nichol Russel Building and the School of Civil Engineering, on the side of Cadigal Green, as shown on the map.
