Next, I want to thank all my friends for their support, incentive and motivation. I also want to thank my parents for all the support and love throughout the years. A special thank to my beautiful grandmother that with her love and affection made me feel to be her special grandson. Finally, but not the least, I want to thank my wife Inês for her support and comprehension and to my daughter Mariana just to make me constantly smile. iii Abstract Nowadays local markets have disappeared and the world lives in a global economy. Due to this reality, every company virtually competes with all others companies in the world. In addition to this, markets constantly search products with higher quality at lower costs, with high customization. Also, products tend to have a shorter period of life, making the demanding more intense. With this scenario, companies, to remain competitive, must constantly adapt themselves to the market changes, i.e., companies must exhibit a great degree of self-organization and self-adaptation. Biology with the millions of years of evolution may offer inspiration to develop new algorithms, methods and techniques to solve real complex problems.

  • Cellular Automata Are Models of Distributed Dynamical Systems
    IOSR Journal of Computer Engineering (IOSR-JCE) e-ISSN: 2278-0661,p-ISSN: 2278-8727, Volume 18, Issue 3, Ver. IV (May-Jun. 2016), PP 92-101 www.iosrjournals.org A New Multi-Agent Game Solver Miklos N Szilagyi Department of Electrical and Computer Engineering University of Arizona, Tucson, AZ 85721 Abstract: A new N-person game solver is presented in this work. The new software is an advance in the whole sate of art for the investigation of N-person games. It is now possible to investigate entire classes of games almost automatically. Moreover, this software makes it trivial to perform a systematic investigation of any game with a multidimensional parameter space. In addition, the payoff functions are no longer limited to quadratic expressions; any elementary mathematical function can easily be used, even in parameterized form. The experimental results are interesting and they very strongly depend on the initial conditions. Keywords: N-person games, Netlogo, Agent-based simulation, Prisoners’ Dilemma, Chicken Dilemma, Complexity. I. Introduction Many complex phenomena can be represented as N-person games in which the participating agents all interact with all the other agents directly or indirectly [1-4]. In the latter case the agents immediately interact only with their immediate neighbors. In this case the agents are simply cells in a cellular automaton. Cellular automata [5-7] are powerful tools for the study of simultaneous operation of a large number of agents, i. e. for the investigation of complex systems and phenomena. Therefore, they are quite suitable for the study of spatial N-person games.

(December 2010) Heather Naomi Hayenga, B.S., University of California, Davis Chair of Advisory Committee: Dr. James E. Moore, Jr. In order to create informed predictive models that capture artery dependent responses during atherosclerosis progression and the long term response to hypertension, one needs to know the structural, biochemical and mechanical properties as a function of time in these diseased states. In the case of hypertension more is known about the mechanical changes; while, less is known about the structural changes over time. For atherosclerotic plaques, more is known about the structure and less about the mechanical properties. We established a congruent multi-scale model to predict the adapted salient arterial geometry, structure and biochemical response to an increase in pressure.

  • Situated Socio-Cognitive and Ecological Simulation of the Triple-Helix Theory of Regional Innovation Dynamics
    Situated Socio-Cognitive and Ecological Simulation of the Triple-Helix Theory of Regional Innovation Dynamics by James R. Morris-King A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama May 3, 2014 Keywords: triple-helix, agent, simulation Copyright 2014 by James R. Morris-King Approved by Levant Yilmaz, Chair, Associate Professor of Computer Science John A. Hamilton Jr., Professor of Computer Science David Umphress, Associate Professor of Computer Science Abstract This dissertation focuses on applying the concept of agent-based ecological simulation to the problem of developing and maintaining regional innovation economies. A simulation model based on a popular model of innovation, the Triple-Helix theory of public-private partnership, is presented. This theory guides the alignment of the three principle sectors of regional and national systems of innovation; academic research, industrial development, and government control. The development and maintenance of systems of innovation has been recognized to be a key driver of economic growth, but the underlying mechanisms which govern these systems have proven difficult for pure statistical analysis to capture. We introduce an agent-based modeling and simulation approach, which leverages eco- logical concepts better suited for describing the behavioral mechanisms of multi-agent, environmentally-situated complex adaptive systems. This model extends the basic formu- lation of the triple-helix to include a new environmentally situated actor, the researcher, which uses indirect signaling to discover and exploit grant-funding. This extension uses principles from classical Predator-Prey interaction and a variant of ant colony optimization, a non-deterministic search algorithm.
