Nt. Overview: procedure overview and scheduling. The scheduling on the model
Nt. Overview: course of action overview and scheduling. The scheduling in the model execution in discrete time steps is shown in Fig 2. The submodels are explained in detail inside the Submodels subsection. The order in which the agents carry out the actions is random, avoiding privileging firstacting consequences. The update from the state variables is asynchronous. Design ideas: fundamental principles. The basic principle underlying this model would be the cooperative phenomenon of indirect reciprocity. When Yamana individuals obtain a beached whale, they face the dilemma of whether to cooperate and share the resource with other Yamana or to defect and exploit the whale alone. They have established a reputation mechanism to promote cooperation and punish defections. Moreover, the model incorporates the fundamental principle of an evolutionary PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25880723 mechanism in imitating the person tactics. Style ideas: emergence. This model shows the emergence of cooperation or defection in Yamana society, a nontrivial outcome that is dependent upon the characteristics of beachings (e.g. stochasticity, spatial distribution, visibility), human walking patterns (e.g. L y fligt, random walk), and other social options including the reputation and imitation processes. Design and style ideas: adaptation. The only adaptive trait of individuals agents is definitely the cooperative trait, i.e. probcooperation, which determines the probability of cooperating when a people agent finds a beached whale.Table 4.

The achievement of people agents is measured by the fitness function (Eq 4), regarding the incomes of meat and social capital individuals reach, which correspond respectively to food and social resources. Social capital abstracts rewards that contribute positively to the agent’s fitness generated from diverse social activities such as understanding transmission, cultural interchange or social relationships, in contrast to pure eating resources collected by food variable. The relative significance of meat versus social capital is weighed by the parameter socialcapitalvsmeatsensitivity. Design ideas: finding out. The model reproduces an evolutionary mechanism of imitatio.
