Collaborative Research: Strategy and Structure: Exploration and Instrument Development

这是一个研究的最佳策略，不同的位置在交换网络中，采用计算机模拟和进化博弈论。现有的工作要么没有注意到人们在交换网络中使用的策略，要么假设所有人都使用相同的简单策略。此外，现有的工作忽略了潜在的合作关系的立场，行动相互影响，即使他们不交换彼此。本计画将演化稳定性的概念延伸至交换网路，并修正复制子动力学以研究交换网路中策略集的假设演化。 该项目的一个核心部分是在万维网上建立一个交互式网站，采用用Java编程的ExNet II模拟。 用户可以通过放置节点和交换关系来构建各种配置的网络。 当模拟器交互时，ExNet将显示所有正在进行的报价、还价、接受和交易。 该网站将在研究和教学之间架起一座桥梁，因为它可以被纳入大学课程，也可以被研究人员用来发展理论思想。 学生选择和设计的策略和结构带来了新鲜的观点，并可能发现模式没有发现的研究人员谁是更有经验的。 该项目有助于对知识网络的基本理论理解，这对于创建未来的通信系统至关重要。基于网络的教育部分为社会科学专业的学生提供了研究类的培训活动，这在他们的学院和大学中往往是缺乏的。

This is a study of optimal strategies for different positions in exchange networks, employing computer simulations and evolutionary game theory. Existing work has either not paid attention to the strategies used by people in exchange networks or has assumed that all people use the same simple strategy. Moreover, existing work has ignored potentially cooperative relations between positions where actions affect one another, even though they do not exchange with one another. The current project extends the concept of evolutionary stability to apply to exchange networks and modifies the replicator dynamics to study the hypothetical evolution of strategy sets in exchange networks. A central part of this project is an interactive site on the World Wide Web, employing the ExNet II simulation programmed in Java. The user can construct networks of various configurations by placing nodes and exchange relations. As simulants interact, ExNet will display all ongoing offers, counteroffers, acceptances and exchanges. The website will bridge between research and instruction, because it can be incorporated in college courses as well as employed by researchers to develop theoretical ideas. Students selecting and designing strategies and structures bring fresh perspectives and may find patterns not found by researchers who are more experienced. This project contributes to fundamental theoretical understanding of knowledge networks, which is essential for creation of the communication systems of the future. The web-based educational component provides research-like training activities for social science students, that are often lacking at their colleges and universities.
