A computational theory of graphical dynamical systems with applications to socio-technical systems.
# 127
Abstract
Graphical Dynamical systems (GDS) are a special type of communicating automata that can be used to model very large socio-technical systems. GDS based 'formal simulations' potentially provide a rigorous, useful new setting for a theory of interaction-based computation. The setting is natural for comprehension of distributed systems characterized by interdependent, but separately functioning sub-parts. Massively parallel and grid computing and the associated algorithm design issues, advanced communication systems, biological networks, epidemiological processes, markets, socio-technical systems are examples of such systems. The talk will describe a computational theory of GDS. The concepts and results shed light on the computational complexity of computing phase space properties of GDS. Applicability of the theory to analyze large scale socio-technical systems will be described.
