中文摘要： 复杂适应系统领域的仿真应用是分布式虚拟环境实用化进程的一个主要方向。虚拟环境引入大量虚拟自治实体驻留其中，用以模拟复杂适应系统中的自适应主体，其终极目标是通过自治实体的相互作用并演化，自下而上地仿真实现复杂适应系统的整体行为。 本项目研究了自治实体自组织结构，给出了一个分布式虚拟环境下自治实体的松耦合体系结构；研究了自治实体个体行为模型，给出了以经验加权有限记忆的自治实体行为反应模型为核心的自治实体个体行为选择模型、基于一种新的邻域相关的加权虚拟行为适应性模型的个体行为适应机制和基于竞争增强学习和历史信念学习的个体行为演化模型；研究了仿真情景适应性演化模型，建立了自治实体群体竞争模型和自治实体合作网络构建模型，通过自治实体群体竞争和合作的并行协同演化，完成仿真情景适应性行为演化。 本项目的研究成果有助于推进分布式虚拟环境的实用化进程，为虚拟环境复杂适应系统仿真演化提供理论和方法。在理论上，项目研究成果给出了虚拟环境复杂适应系统自组织仿真演化的理论模型；在实践上，项目研究成果为虚拟环境复杂适应系统自组织仿真演化提供建模方法和原型参考。

英文摘要： Complex system simulation is an important practical field of collaborative virtual environment. To simulate a complex system, a mass of virtual autonomous entities are introduced to resident in virtual environment to simulate adaptive agents in complex system. The ultimate target of virtual environment simulation is emerging well-regulated macro-behavior to simulate a complex system with bottom-up approach through co-evolution and co-acting among all autonomous entities in virtual environment. This project has developed a loose coupling architecture for as a self-organized infrastructure of autonomous entities in a distributed virtual environment. Furthermore, this project has developed a individual behavior model for autonomous entity which involving an individual behaivor-selecting model with a limited memory-weighted behavior-reaction model,an individual behavior-adapting model with a neighborhood correlated empirical weighted fictitious play adptive model, and an individual behavior-evolution model based on competition enhancement learning and history beliefs learning. And, this project has proposed a competition model for autonomous entity swarm and a autonomous entity cooperation-network constructing model. The co-evolution of swarm competition and individual cooperation leads to behavior adaptive evolution of complex situation simultaion. In theory, the achievements of the project proposed a theoretic model for virtual environment based complex system self-organized evolution simulation. And, in practice, the achievements also provides modeling technique and reference prototypes. Hence, the project achievements provides a theoretical and methodological support for complex system simulaiton in collaborative virtual environment to promote practical progress of virtual environment.
