Cellular Ecolab

In the original speciication of the Ecolab model, spatial variation of the system's variables was included, with an additional migration operator introduced proportional to the divergence of the species density. Suitably discretized, the model then consists of a number of cells, each running the non-spatial Ecolab model, linked together by the migration operator. This paper reports on the imple...

Going Stupid with EcoLab

In 2005, Railsback et al. proposed a very simple model (Stupid Model) that could be implemented within a couple of hours, and later extended to demonstrate the use of common ABM platform functionality. They provided implementations of the model in several agent based modelling platforms, and compared the platforms for ease of implementation of this simple model, and performance. In this paper, ...

Ecolab: Where to Now?

By adding the concept of random embryology with locality to Lotka-Volterra population equations, a description of biological evolution is created. This model is called Ecolab. Computer simulations of these systems display self organised criticality, with power law behaviour for species lifetimes that stand in stark contrast to gradualism. This paper explores areas of future research with this m...

Ecolab, Webworld and self-organisation

Ecolab and Webworld are both models of evolution produced by adding evolution to ecological equations. They differ primarily in the form of the ecological equations. Both models are self-organised to a state where extinctions balance speciations. However, Ecolab shows evidence of this self-organised state being critical, whereas Webworld does not. This paper examines the self-organised states o...
