Penna bit-string model with constant population
S. Moss de Oliveira, P. M. C de Oliveira, J. S. Sa Martins
We removed from the Penna model for biological ageing any random killing Verhulst factor. Deaths are due only to genetic diseases and the population size is fixed, instead of fluct…

The evolutionary advantage of diploid sex
A. O. Sousa, S. Moss de Oliveira, J. S. Sa Martins
We modify the Penna Model for biological aging, which is based on the mutation-accumulation theory, in order to verify if there would be any evolutionary advantage of triploid over…

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…
