A new, efficient algorithm for the Forest Fire Model
Gunnar Pruessner, Henrik Jeldtoft Jensen
The Drossel-Schwabl Forest Fire Model is one of the best studied models of non-conservative self-organised criticality. However, using a new algorithm, which allows us to study the…
Anisotropy and universality: the Oslo model, the rice pile experiment and the quenched Edwards-Wilkinson equation
Gunnar Pruessner, Henrik Jeldtoft Jensen
We show that any amount of anisotropy moves the Oslo model to another known universality class, the exponents of which can be derived exactly. This amounts to an exact solution of…
Fluctuation spectrum and size scaling of river flow and level
Kajsa Dahlstedt, Henrik Jeldtoft Jensen
We describe the statistical properties of two large river systems: the Danube and the Mississippi. The properties of the two rivers are compared qualitatively to the general proper…
Network properties, species abundance and evolution in a model of evolutionary ecology
Paul Anderson, Henrik Jeldtoft Jensen
We study the evolution of the network properties of a populated network embedded in a genotype space characterised by either a low or a high number of potential links, with particu…
Darwinian Selection and Non-existence of Nash Equilibria
Daniel Eriksson, Henrik Jeldtoft Jensen
We study selection acting on phenotype in a collection of agents playing local games lacking Nash equilibria. After each cycle one of the agents losing most games is replaced by a…
