Within a network new links of the same kind can derive from previous links, but also new kinds of links/relations derive from previous relations, thus new kinds (levels) of networks derive from a given network. Both phenomena would need a systematic theory (especially in social domains), good definitions, and possibly simulation models for understanding their real dynamics and predictive power. While...
This paper focuses on the emergence of criminal activity due to the unmet human needs of those living in Rio's favelas. An agent-based model is developed to explore how human needs, environmental factors, and individual attributes impact state-level behaviors. The emergence of organized crime is observed as "common" criminals turn into gang members. The prevention of conflict requires policies...
Looking to the operation of an agent architecture, ie. its goal generation and maintenance processing, is relevant to understand fully how a moral based agent takes appropriate and diverse decisions within social situations of serious games. How decision does happen is a complex issue and the major motivation of this paper, and our answer, the proposal of a new architecture, is supported on the clarification...
This article presents the results of a Dodds-Watts generalized model of social and biological contamination implementation applied to technology adoption. We simulated four digital divide evolution theories proposed by Martin by setting the model's parameters and using two societies divided by their average income. We also show how important is the threshold (inversely proportional to the income)...
Parallel simulations involving multiple agents is a hard task to accomplish due the high dependence that is hold by the agents' interactions. These interactions usually are defined by environmental constraints which specify rules defining how agents interact with each other. One of such predetermined rules is called von Neumann neighborhood, which is applied, specifically, to two-dimensional lattices...
In multiagent systems, agents may cooperate in order to achieve their goals. One possible form of cooperation is through coalition formation. Assuming that agents are selfish, or potentially unreliable, they should implement some mechanism to deal with the uncertainty arising from the cooperation. One possibility is the use of the trust notion, which provides a mechanism for modeling and reasoning...
Integrating "diversity" into rational choice models is key to achieve interesting results on collective action in which there is alternation between cooperation and defection in a feedback way. As agent-based models are useful tools to handle flexible assumptions on strategic behavior in simulated environments, in this paper it is shown how this methodological approach could help to reach...
Escape route planning in emergency situations generates interest among researches in many different areas. Computer Science contributes to this by developing simulations of real world situations. An escape route can be regarded as a weighted graph where the labels associated with its edges are determined by the distance between two connected vertexes. Hence, given a starting vertex, it is possible...
Segregation is perceived as a large-scale urban phenomenon, but emerges from the interactions between individuals at a local level. There are three patterns of residential segregation that are known by the names of those who formalized empirical evidences on the spatial distribution of social classes: they are called Kohl, Burgess and Hoyt. Comprehend how this patterns emerge and evolve along the...
