S.Cajueiro, Daniel OliveiraAndrade, Roberto Fernandes Silva2012-04-26T11:32:35Z20101434-6028http://www.repositorio.ufba.br/ri/handle/ri/5750v. 76, n. 1Acesso restrito: Texto completo. p. 147-156.The minority game (MG) is used as a source of information to design complex networks where the nodes represent the playing agents. Differently from classical MG consisting of independent agents, the current model rules that connections between nodes are dynamically inserted or removed from the network according to the most recent game outputs. This way, preferential attachment based on the concept of social distance is controlled by the agents wealth. The time evolution of the network topology,quantitatively measured by usual parameters, is characterized by a transient phase followed by a steady state, where the network properties remain constant. Changes in the local landscapes around individual nodes depend on the parameters used to control network links. If agents are allowed to access the strategies of their network neighbors, a feedback effect on the network structure and game outputs is observed. Such effect, known as herding behavior, considerably changes the dependence of volatility σ on memory size: it is shown that the absolute value of σ as well as the corresponding value of memory size depend both on the network topology and on the way along which the agents make their playing decisions in each game round.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-04-26T11:32:35Z No. of bitstreams: 1 __www.springerlink.com_c...t776l7t876409286_fulltext.pdf: 395064 bytes, checksum: aa7f9f3e8c63feca3523a7eeee415fdb (MD5)Made available in DSpace on 2012-04-26T11:32:35Z (GMT).
