Conventions spreading in open-ended systems
E. Brigatti, I. Roditi
We introduce a simple open-ended model that describes the emergence of a shared vocabulary. The ordering transition toward consensus is generated only by an agreement mechanism. Th…
Consequence of reputation in an open-ended Naming Game
Edgardo Brigatti
We study a modified version of the Naming Game, a recently introduced model which describes how shared vocabulary can emerge spontaneously in a population without any central contr…
An individual based model with global competition interaction: fluctuations effects in pattern formation
E. Brigatti, V. Schwammle, Minos A. Neto
We present some numerical results obtained from a simple individual based model that describes clustering of organisms caused by competition. Our aim is to show how, even when a de…
Speciational view of macroevolution: are micro and macroevolution decoupled?
V. Schwammle, E. Brigatti
We introduce a simple computational model that, with a microscopic dynamics driven by natural selection and mutation alone, allows the description of true speciation events. A stat…
Sharp gene pool transition in a population affected by phenotype-based selective hunting
E. Brigatti, J. S. Sa' Martins, I. Roditi
We use a microscopic model of population dynamics, a modified version of the well known Penna model, to study some aspects of microevolution. This research is motivated by recent r…
Scaling properties of the Penna model
E. Brigatti, J. S. Sa' Martins, I. Roditi
We investigate the scaling properties of the Penna model, which has become a popular tool for the study of population dynamics and evolutionary problems in recent years. We find th…
