Discrete Models of Complex Systems

Complex systems investigate the emergence of complex global behavior through the local interactions of a large collection of well understood components. Interdisciplinary by nature, it encompasses problems encountered in diverse disciplines from physics to economics, biology, mathematics, computer sciences from which it borrows both models and tools.
Discrete models of complex systems provide formal models that can be used both as modeling tools convenient for computer simulation to study particular complex systems and as a simple framework to study, define and characterize fundamental properties of complex systems.
Theoretical Computer Science, through the theory of computation, provide valuable tools to design efficient algorithms or, when not possible, prove unpredictability or characterize the inherent difficulty of predictability in discrete models of complex systems like cellular automata, boolean or regulatory genetic networks, social science models, sand piles and Ising like models.
This Workshop aims at gathering researchers from all these horizons, setting off interactions between them. It will also be an occasion to share recent results with the global perspective of discrete complex systems.

Confirmed Speakers


Hôtel Dupanloup : 1, rue Dupanloup - 45000 ORLEANS - FR

The conference venue is unique. Located right next to the Orléans’ cathedral, the episcopal palace of Orléans, built between 1635 and 1641, locally known as the Hôtel Dupanloup, is a classical French building which served until 1905 of residence to the bishops of Orléans.  Since 2014, the renewed palace hosts the International University Center for Research and Le Studium Loire Valley Institute for Advanced Studies.

Participants will be welcomed in this exceptional surrounding, blending Middle Age and Renaissance cultures with modern design and will have the opportunity to discover French cuisine and wines.
