JASSSJournal of Artificial Societies and Social Simulation: For the exploration and understanding of social processes by means of computer simulationOpinion Dynamics: the Effect of the Number of Peers Met at Once- (Found July 2, 2008 ) Diemo Urbig, Jan Lorenz and Heiko Herzberg: The opinion dynamics model introduced by Deffuant and Weisbuch as well as the one by Hegselmann and Krause are rather similar. In both models individuals are assumed to have opinions about an issue, they meet and discuss, and they may adapt their opinions towards the other agents opinions or may ignore each other if their positions are too different. Both models differ with respect to the number of peers they meet at once. Furthermore the model by...http://jasss.soc.surrey.ac.uk/11/2/4.html Reinforcement Learning Dynamics in Social Dilemmas- (Found July 2, 2008 ) Segismundo S. Izquierdo, Luis R. Izquierdo and Nicholas M. Gotts: In this paper we replicate and advance Macy and Flache's (2002; Proc. Natl. Acad. Sci. USA, 99, 72297236) work on the dynamics of reinforcement learning in 22 (2-player 2-strategy) social dilemmas. In particular, we provide further insight into the solution concepts that they describe, illustrate some recent analytical results on the dynamics of their model, and discuss the robustness of such results to occasional mistakes made...http://jasss.soc.surrey.ac.uk/11/2/1.html Progress in Model-To-Model Analysis- (Found July 2, 2008 ) Juliette Rouchier, Claudio Cioffi-Revilla, J.

By permitting the user to specify: (i) different resource profiles ranging from a purely agrarian economy to one based on the artisanal or industrial extraction of alluvial or kimberlite diamonds; (ii) different patterns of ethnic domination, ethnic polarization, and...http://jasss.soc.surrey.ac.uk/11/2/7.html Review of: Simulation Modeling and Analysis with ARENA- (Found July 2, 2008 ) Review of: Simulation Modeling and Analysis with ARENA by Altiok, T. and Melamed, Benjamin, reviewed by Alessandro Raimondihttp://jasss.soc.surrey.ac.uk/11/2/reviews/raimondi.html |
