一种新的计算方法:粒度进化计算   总被引:4,自引:4,他引:4  
从分析进化计算的起源入手,总结了进化计算产生的根源,然后探讨了人类进化——文化进化的基本特征,模仿进化计算的来源机制,提出了粒度进化计算。如果说进化计算是模拟达尔文生物进化机制而发展起来的一种计算方法,那么粒度进化计算则是在模仿文化进化机制的基础上,综合了Agent技术以及粒度计算、进化计算的理论和方法而提出的一种计算方法。文中,从群进化和超群进化两方面来介绍粒度进化计算的基本原理和方法,并给出了基于粒度Agent系统的粒度进化递归模型。  相似文献

Sky Computing   总被引:1,自引:0,他引:1  
Infrastructure-as-a-service (IaaS) cloud computing is revolutionizing how we approach computing. Compute resource consumers can eliminate the expense inherent in acquiring, managing, and operating IT infrastructure and instead lease resources on a pay-as-you-go basis. IT infrastructure providers can exploit economies of scale to mitigate the cost of buying and operating resources and avoid the complexity required to manage multiple customer-specific environments and applications. The authors describe the context in which cloud computing arose, discuss its current strengths and shortcomings, and point to an emerging computing pattern it enables that they call sky computing.  相似文献

Granular Computing   总被引:5,自引:1,他引:5  
The basic ideas and principles of granular computing (GrC) have been studied explicitly or implicitly in many fields in isolation. With the recent renewed and fast growing interest, it is time to extract the commonality from a diversity of fields and to study systematically and formally the domain independent principles of granular computing in a unified model. A framework of granular computing can be established by applying its own principles. We examine such a framework from two perspectives,granular computing as structured thinking and structured problem solving. From the philosophical perspective or the conceptual level,granular computing focuses on structured thinking based on multiple levels of granularity. The implementation of such a philosophy in the application level deals with structured problem solving.  相似文献

Computing Style     
Shape grammars are frequently used in analyzing style in architecture and other areas of design. But this is a more subtle task than is usually realized, and some grammatical approaches to design analysis are logically suspect. We examine the framework articulated by Stiny and Mitchell in 1978, fill in the operational gaps, and propose a more comprehensively considered approach to using grammars to compute style.  相似文献
