Transcript of Adapting the Bak-Sneppen Model to a Dynamic and Partially Connected Grid of Hierarchical Species
Adapting the Bak-Sneppen Model to a Dynamic and Partially Connected Grid of Hierarchical Species C.M. Fernandes (Technical Univ. of Lisbon), J.L.J. Laredo, J.J. Merelo, C. Cotta, A.C.Rosa
This paper investigates the behaviour of a variant of the Bak-Sneppen model in which the species move on 2D habitat according to a simple set of rules.
