Should retirement age be coupled to life expectancy ?
J. S. Sa Martins, D. Stauffer
Increasing every year the retirement age by the same amount as the increase of the life expectancy gives roughly stable ratios of the number of retired to working-age people in ind…
Simple Bit-String Model for Lineage Branching
P. M. C. de Oliveira, J. S. Sa' Martins, D. Stauffer +1
We introduce a population dynamics model, where individual genomes are represented by bit-strings. Selection is described by death probabilities which depend on these genomes, and…
Computer Simulations for Biological Ageing and Sexual Reproduction
D. Stauffer, P. M. C. de Oliveira, S. Moss de Oliveira +2
The sexual version of the Penna model of biological ageing, simulated since 1996, is compared here with alternative forms of reproduction as well as with models not involving agein…
Evolution and Ageing
S. Moss de Oliveira, Domingos Alves, J. S. Sa Martins
The idea of this review is to connect the different models of evolution to those of biological ageing through Darwin's theory. We start with the Eigen model of quasispecies for mic…
