1. O modelo de Axelrod com tensão superficial / Axelrod\ s model with surface tension
Nesta dissertação foram estudados alguns modelos vetoriais que pretendem modelar e descrever alguns aspectos de sistemas sociais e de sua organização cultural. Partimos do modelo de Axelrod, um processo estocástico definido em uma rede, e introduzimos uma pequena alteração no modelo que desencadeou mudanças qualitativas interessantes, especialmente o

2. The stochastic modeling applied to the maintenance of cultural diversity / A modelagem estocástica aplicada à manutenção da diversidade cultural
The sociocultural stochastic modeling introduced by Robert Axelrod is traditionally referred to as the maintenance of cultural diversity. Since it generates the appearance of heterogeneities on a steady state, even the primordial interaction tends to gauge the interactors. Due to its simplicity, numerous interpretations of this model were studied, as well as

3. Chromosomal drive and the evolution of meiotic nondisjunction and trisomy in humans
Trisomy is a genetic abnormality of considerable medical importance. The most familiar example is trisomy 21, which causes Down Syndrome [Cummings, M. R. (1988) Human Heredity: Principles and Issues (West Publishing Company, New York)]. In a classic paper, Axelrod and Hamilton [Axelrod, R. & Hamilton, W. D. (1981) Science 211, 1390–1396] offered a chromoso

4. Working memory constrains human cooperation in the Prisoner’s Dilemma
Many problems in human society reflect the inability of selfish parties to cooperate. The “Iterated Prisoner’s Dilemma” has been used widely as a model for the evolution of cooperation in societies. Axelrod’s computer tournaments and the extensive simulations of evolution by Nowak and Sigmund and others have shown that natural selection can favor coo

5. Chaos and the evolution of cooperation.
The "iterated prisoner's dilemma" is the most widely used model for the evolution of cooperation in biological societies. Here we show that a heterogeneous population consisting of simple strategies, whose behavior is totally specified by the outcome of the previous round, can lead to persistent periodic or highly irregular (chaotic) oscillations in the freq
