The Complexity Of Cooperation
''The Complexity of Cooperation'', by Robert Axelrod, is the sequel to ''The Evolution of Cooperation''. It is a compendium of seven articles that previously appeared in journals on a variety of subjects. The book extends Axelrod's method of applying the results of game theory, in particular that derived from analysis of the Prisoner's Dilemma (IPD) problem, to real world situations. Prisoner's Dilemma findings Axelrod explains the Tit for tat (TFT or T4T) strategy emerged as the most robust option in early IPD tournaments on computer. This strategy combines a willingness to cooperate with a determination to punish non-cooperation. In these articles, however, he shows, that under more complex circumstances, such as the possibility of error, strategies that are a little more cooperative or a little less punitive do even better than TFT. Generous TFT, or GTFT, cooperates a bit more often than TFT, while Contrite TFT or CTFT defects less frequently. Applications Axelrod applies var ...

Robert Axelrod
Robert Marshall Axelrod (born May 27, 1943) is an American political scientist. He is Professor of Political Science and Public Policy at the University of Michigan where he has been since 1974. He is best known for his interdisciplinary work on the evolution of cooperation. His current research interests include complexity theory (especially agent-based modeling), international security, and cyber security. His research includes innovative approaches to explaining conflict of interest, the emergence of norms, how game theory is used to study cooperation, and cross-disciplinary studies on evolutionary processes. Biography Axelrod received his B.A. in mathematics from the University of Chicago in 1964. In 1969, he received his Ph.D. in political science from Yale University for a thesis entitled ''Conflict of interest: a theory of divergent goals with applications to politics''. He taught at the University of California, Berkeley, from 1968 until 1974. Among his honors and awa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, ''The Daily Princetonian'', and later added book publishing to it ...

The Evolution Of Cooperation
''The Evolution of Cooperation'' is a 1984 book written by political scientist Robert Axelrod that expands upon paper of the same name written by Axelrod and evolutionary biologist W.D. Hamilton. The book details a theory on the emergence of cooperation between individuals, drawing from game theory and evolutionary biology. Since 2006, reprints of the book have included a foreword by Richard Dawkins and have been marketed as a revised edition. The book provides an investigation into how cooperation can emerge and persist (also known as cooperation theory) as elucidated by the application of game theory. The book provides a detailed explanation of the evolution of cooperation, beyond traditional game theory. Academic literature regarding forms of cooperation that are not easily explained in traditional game theory, especially when considering evolutionary biology, largely took its modern form as a result of Axelrod's and Hamilton's influential 1981 paper and the subsequent book. ...

Game Theory
Game theory is the study of mathematical models of strategic interactions among rational agents. Myerson, Roger B. (1991). ''Game Theory: Analysis of Conflict,'' Harvard University Press, p.&nbs1 Chapter-preview links, ppvii–xi It has applications in all fields of social science, as well as in logic, systems science and computer science. Originally, it addressed two-person zero-sum games, in which each participant's gains or losses are exactly balanced by those of other participants. In the 21st century, game theory applies to a wide range of behavioral relations; it is now an umbrella term for the science of logical decision making in humans, animals, as well as computers. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum game and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathema ...

Prisoner's Dilemma
The Prisoner's Dilemma is an example of a game analyzed in game theory. It is also a thought experiment that challenges two completely rational agents to a dilemma: cooperate with their partner for mutual reward, or betray their partner ("defect") for individual reward. This dilemma was originally framed by Merrill Flood and Melvin Dresher while working at RAND in 1950. Albert W. Tucker appropriated the game and formalized it by structuring the rewards in terms of prison sentences and named it "prisoner's dilemma". William Poundstone in his 1993 book ''Prisoner's Dilemma'' writes the following version:Two members of a criminal gang are arrested and imprisoned. Each prisoner is in solitary confinement with no means of speaking to or exchanging messages with the other. The police admit they don't have enough evidence to convict the pair on the principal charge. They plan to sentence both to two years in prison on a lesser charge. Simultaneously, the police offer each prisoner a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tit For Tat
Tit for tat is an English saying meaning "equivalent retaliation". It developed from "tip for tap", first recorded in 1558. It is also a highly effective strategy in game theory. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. Game theory Tit-for-tat has been very successfully used as a strategy for the iterated prisoner's dilemma. The strategy was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Notably, it was (on both occasions) both the simplest strategy and the most successful in direct competition. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. This is similar to reciprocal altruism in biology. History The term develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Fukuyama
Francis Yoshihiro Fukuyama (; born October 27, 1952) is an American political scientist, political economist, international relations scholar and writer. Fukuyama is known for his book ''The End of History and the Last Man'' (1992), which argues that the worldwide spread of liberal democracies and free-market capitalism of the West and its lifestyle may signal the end point of humanity's sociocultural evolution and political struggle and become the final form of human government, an assessment met with criticisms. In his subsequent book ''Trust: Social Virtues and Creation of Prosperity'' (1995), he modified his earlier position to acknowledge that culture cannot be cleanly separated from economics. Fukuyama is also associated with the rise of the neoconservative movement, from which he has since distanced himself. Fukuyama has been a senior fellow at the Freeman Spogli Institute for International Studies since July 2010 and the Mosbacher Director of the Center on Democracy, D ...

Psychology Books
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Books About Game Theory
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is ''codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called a bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
