Small world effects in evolution
Franco Bagnoli, Michele Bezzi
For asexual organisms point mutations correspond to local displacements in the genotypic space, while other genotypic rearrangements represent long-range jumps. We investigate the…
Eigen's Error Threshold and Mutational Meltdown in a Quasispecies Model
F. Bagnoli, M. Bezzi
We introduce a toy model for interacting populations connected by mutations and limited by a shared resource. We study the presence of Eigen's error threshold and mutational meltdo…
Phase Disorder Effects in a Cellular Automaton Model of Epidemic Propagation
M. Bezzi, R. Livi
A deterministic cellular automaton rule defined on the Moore neighbourhood is studied as a model of epidemic propagation. The directed nature of the interaction between cells allow…
Species Formation in Simple Ecosystems
Franco Bagnoli, Michele Bezzi
In this paper we consider a microscopic model of a simple ecosystem. The basic ingredients of this model are individuals, and both the phenotypic and genotypic levels are taken in…
