Download or read book An Introduction to Agent Based Modeling written by Uri Wilensky and published by MIT Press. This book was released on 2015-04-03 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and hands-on introduction to the core concepts, methods, and applications of agent-based modeling, including detailed NetLogo examples. The advent of widespread fast computing has enabled us to work on more complex problems and to build and analyze more complex models. This book provides an introduction to one of the primary methodologies for research in this new field of knowledge. Agent-based modeling (ABM) offers a new way of doing science: by conducting computer-based experiments. ABM is applicable to complex systems embedded in natural, social, and engineered contexts, across domains that range from engineering to ecology. An Introduction to Agent-Based Modeling offers a comprehensive description of the core concepts, methods, and applications of ABM. Its hands-on approach—with hundreds of examples and exercises using NetLogo—enables readers to begin constructing models immediately, regardless of experience or discipline. The book first describes the nature and rationale of agent-based modeling, then presents the methodology for designing and building ABMs, and finally discusses how to utilize ABMs to answer complex questions. Features in each chapter include step-by-step guides to developing models in the main text; text boxes with additional information and concepts; end-of-chapter explorations; and references and lists of relevant reading. There is also an accompanying website with all the models and code.

Available in PDF, EPUB and Kindle. Book excerpt: Multi-agent systems have been a focus of studies for more than 25 years. Yet, despite substantial effort of an active research community, modeling of multi-agent systems still lacks complete and proper definition, general acceptance, and practical application. This book provides the Agent-Modeling Language (AML), a comprehensive modeling language as an extension of UML 2.0, concentrating on multi-agent systems and applications.

Download or read book The Principal Agent Model and the European Union written by Tom Delreux and published by Springer. This book was released on 2017-10-16 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the use and limitations of the principal-agent model in a context of increasingly complex political systems such as the European Union. Whilst a number of conceptual, theoretical and methodological challenges need to be addressed, the authors show that the principal-agent model can still provide deeper insights into a wide range of political phenomena. Through an empirical analysis of multiple principal-agent relations in the EU, covering a variety of policy fields and political actors, the volume refines our theoretical understanding of the politics of delegation and discretion in the EU. It will appeal to scholars in interested in EU politics and policy, public administration and governance, and international organisations. The chapter ‘Multiple principals preferences, different types of oversight mechanisms, and agent’s discretion in trade negotiations’ is published open access under a CC BY 4.0 license via link.springer.com.

Download or read book Design of Agent based Models written by Tomáš Šalamon and published by Tomáš Bruckner. This book was released on 2011 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are plenty of publications dealing with the theory of multi-agent systems and agent-based simulations, information about the practical development of such systems is scarce. The aim of this book is to fill this empty space and to provide knowledge about design and development of agent-based simulations in an easy and comprehensible way. The book begins with the fundamentals of multi-agent systems, agent principles and their interaction, and goes on to discuss the philosophy of agent-based programming. Agent-based models - like any other scientific method - have drawbacks and limitations, which are presented in the book as well. The main portion of the text is then devoted to a description of methodology and best practices for the design and development of agent-based simulation software. The methodology (called Agentology) guides the reader through the entire development process, from the formal definition of the problem, through conceptual modeling and the selection of the particular development platform, to the programming and debugging of the code itself and the final assessment of the model. The visual language as the means of representation of the conceptual model is included. The reader is also presented with a comparison of present multi-agent development environments and tools, which could be helpful for the selection of appropriate development instruments. Given that the theoretical foundation is presented in an accessible way and supported by many practical examples, figures, schemes and source codes, this publication is especially suitable as a textbook for introductory graduate-level courses on multi-agent systems and agent-based modeling. Besides appealing to students and the scientific community, the monograph can aid software architects and developers who are not familiar with agent principles, conveying valuable insights into this distinct computer paradigm.

Available in PDF, EPUB and Kindle. Book excerpt: As Michael finally finds the person who left him for dead, can the love he'd found with Alex survive the fallout? Michael survived a hate crime but is haunted by memories beyond his grasp and plagued by relentless nightmares. When he leaves his life as a catwalk model ad returns home to confront his past, it’s his present in the shape his persistent agent, Alex, who refuses to leave him alone. Once he thought he loved Alex, but their relationship crumbled is destroyed when Alex's well-intentioned but suffocating tendency to protect Michael becomes their downfall. Michael loves Alex, and always will, and protecting the man he loves is everything. Only, in protecting Michael he loses everything, and he wants a second chance to prove that he can change. When he’s drawn into the darkness of Michael’s past, he’s determined to be a very different kind of person—someone Michael can depend on. Secrets rarely remain hidden, and the pursuit of the person who nearly took Michael's life presents a formidable challenge. The prospect of remaining passive becomes increasingly difficult as danger looms closer. Will history repeat itself, causing Alex to lose Michael once more?

Download or read book Economics with Heterogeneous Interacting Agents written by Alessandro Caiani and published by Springer. This book was released on 2016-09-21 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical guide to Agent Based economic modeling, adopting a “learning by doing” approach to help the reader master the fundamental tools needed to create and analyze Agent Based models. After providing them with a basic “toolkit” for Agent Based modeling, it present and discusses didactic models of real financial and economic systems in detail. While stressing the main features and advantages of the bottom-up perspective inherent to this approach, the book also highlights the logic and practical steps that characterize the model building procedure. A detailed description of the underlying codes, developed using R and C, is also provided. In addition, each didactic model is accompanied by exercises and applications designed to promote active learning on the part of the reader. Following the same approach, the book also presents several complementary tools required for the analysis and validation of the models, such as sensitivity experiments, calibration exercises, economic network and statistical distributions analysis. By the end of the book, the reader will have gained a deeper understanding of the Agent Based methodology and be prepared to use the fundamental techniques required to start developing their own economic models. Accordingly, “Economics with Heterogeneous Interacting Agents” will be of particular interest to graduate and postgraduate students, as well as to academic institutions and lecturers interested in including an overview of the AB approach to economic modeling in their courses.

Download or read book Agent Based Modeling written by Norman Ehrentreich and published by Springer Science & Business Media. This book was released on 2007-10-30 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reconciles the existence of technical trading with the Efficient Market Hypothesis. By analyzing a well-known agent-based model, the Santa Fe Institute Artificial Stock Market (SFI-ASM), it finds that when selective forces are weak, financial evolution cannot guarantee that only the fittest trading rules will survive. Its main contribution lies in the application of standard results from population genetics which have widely been neglected in the agent-based community.

Available in PDF, EPUB and Kindle. Book excerpt: To fully understand not only the past, but also the trajectories, of human societies, we need a more dynamic view of human social systems. Agent-based modeling (ABM), which can create fine-scale models of behavior over time and space, may reveal important, general patterns of human activity. Agent-Based Modeling for Archaeology is the first ABM textbook designed for researchers studying the human past. Appropriate for scholars from archaeology, the digital humanities, and other social sciences, this book offers novices and more experienced ABM researchers a modular approach to learning ABM and using it effectively. Readers will find the necessary background, discussion of modeling techniques and traps, references, and algorithms to use ABM in their own work. They will also find engaging examples of how other scholars have applied ABM, ranging from the study of the intercontinental migration pathways of early hominins, to the weather–crop–population cycles of the American Southwest, to the trade networks of Ancient Rome. This textbook provides the foundations needed to simulate the complexity of past human societies, offering researchers a richer understanding of the past—and likely future—of our species.

Download or read book Agent Based Modeling of Social Conflict written by Carlos M. Lemos and published by Springer. This book was released on 2017-10-24 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief revisits and extends Epstein’s classical agent-based model of civil violence by considering important mechanisms suggested by social conflict theories. Among them are: relative deprivation as generator of hardship, generalized vanishing of the risk perception (‘massive fear loss’) when the uprisings surpass a certain threshold, endogenous legitimacy feedback, and network influence effects represented by the mechanism of dispositional contagion. The model is explored in a set of computer experiments designed to provide insight on how mechanisms lead to increased complexity of the solutions. The results of the simulations are compared with statistical analyses of estimated size, duration and recurrence of large demonstrations and riots for eight African countries affected by the “Arab Spring,” based on the Social Conflict Analysis Database. It is shown that the extensions to Epstein’s model proposed herein lead to increased “generative capacity” of the agent-based model (i.e. a richer set of meaningful qualitative behaviors) as well the identification of key mechanisms and associated parameters with tipping points. The use of quantitative information (international indicators and statistical analyses of conflict events) allows the assessment of the plausibility of input parameter values and simulated results, and thus a better understanding of the model’s strengths and limitations. The contributions of the present work for understanding how mechanisms of large scale conflict lead to complexbehavior include a new form of the estimated arrest probability, a simple representation of political vs economic deprivation with a parameter which controls the `sensitivity' to value, endogenous legitimacy feedback, and the effect of network influences (due to small groups and “activists”). In addition, the analysis of the Social Conflict Analysis Database provided a quantitative description of the impact of the “Arab Spring” in several countries focused on complexity issues such as peaceful vs violent, spontaneous vs organized, and patterns of size, duration and recurrence of conflict events in this recent and important large-scale conflict process. This book will appeal to students and researchers working in these computational social science subfields.
