    The evolutionary minority game with local coordination
    (2003) Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J.
    "We discuss a modification of the evolutionary minority game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual relaxation dynamics can be made in which each agent updates her decision depending upon her neighborhood. We report numerical results for the topologies of a ring, a torus and a random graph changing the size of the neighborhood. We find the surprising result that in the EMG a better coordination (a lower frustration) can be achieved if agents base their actions on local information disregarding the global trend in the self-segregation process."

    Impacto de la estrategia de marketing en las ventas: el caso de un duopolio visto a través de la teoría dinámica de juegos
    (2008) Rocatti, Gabriela; Szulanski, Fabián
    "El presente trabajo desarrolla un modelo de simulación continua para la comprensión del comportamiento competitivo entre las dos empresas de un duopolio, y su efecto sobre las ventas. Entre las herramientas utilizadas está la Dinámica de sistemas y la Teoría de juegos. También se hace referencia a conceptos de marketing y economía."

    Order and disorder in the local evolutionary minority game
    (2005) Burgos, Enrique; Ceva, Horacio; Perazzo, Roberto P. J.
    "We study a modification of the Evolutionary Minority Game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual relaxation dynamics can be made in which each agent updates her decision scheme depending upon the options made in her immediate neighborhood. We name this model the Local Evolutionary Minority Game (LEMG). We report numerical results for the topologies of a ring, a torus and a random graph changing the size of the neighborhood.We focus our discussion in a one-dimensional system and perform a detailed comparison of the results obtained from the random relaxation dynamics of the LEMG and from a linear chain of interacting spin-like variables with temperature. We provide a physical interpretation of the surprising result that in the LEMG a better coordination (a lower frustration) is achieved if agents base their actions on local information.We show how the LEMG can be regarded as a model that gradually interpolates between a fully ordered, antiferromagnetic-like system, and a fully disordered system that can be assimilated to a spin glass."
