Self-Organized Criticality, Optimization and Biodiversity
Roberto N. Onody, Paulo A. de Castro
By driven to extinction species less or poorly adapted, the Darwinian evolutionary theory is intrinsically an optimization theory. We investigate two optimization algorithms with s…
Complex network study of Brazilian soccer players
Roberto N. Onody, Paulo A. de Castro
Although being a very popular sport in many countries, soccer has not received much attention from the scientific community. In this paper, we study soccer from a complex network p…
Nonlinear Barabási-Albert Network
R. N. Onody, P. A. de Castro
In recent years there has been considerable interest in the structure and dynamics of complex networks. One of the most studied networks is the linear Barabási-Albert model. Here w…
The Branched Polymer Growth Model Revisited
Ubiraci P. C. Neves, Andre L. Botelho, Roberto N. Onody
The Branched Polymer Growth Model (BPGM) has been employed to study the kinetic growth of ramified polymers in the presence of impurities. In this article, the BPGM is revisited on…
Optimization and self-organized criticality in a magnetic system
R. N. Onody, P. A. de Castro
We propose a kind of Bak-Sneppen dynamics as a general optimization technique to treat magnetic systems. The resulting dynamics shows self-organized criticality with power law scal…
The Heumann-Hotzel model for aging revisited
Nazareno G. F. de Medeiros, Roberto N. Onody
Since its proposition in 1995, the Heumann-Hotzel model has remained as an obscure model of biological aging. The main arguments used against it were its apparent inability to desc…
