Player Guild Dynamics And Evolution In Massively Multiplayer Online Games, Chien Hsun Chen, J. L. Hsieh, C. T. Sun

In the latest versions of massively multiplayer online games (MMOGs), developers have purposefully made guilds part of game environments. Guilds represent a powerful method for giving players a sense of online community, but there is little quantitative data on guild dynamics. To address this topic, we took advantage of a feature found in one of today’s most popular MMOGs (World of Warcraft) to collect in-game data: user interfaces that players can modify and refine. In addition to collecting data on in-game player activities, we used this feature to observe and investigate how players join and leave guilds. Data were analyzed …

In this article, we present a genetic algorithm (GA) as one branch of artificial intelligence (AI) for the optimization-design of the artificial magnetic metamaterial whose structure is automatically generated by computer through the filling element methodology. A representative design example, metamaterials with permeability of negative unity, is investigated and the optimized structures found by the GA are presented. It is also demonstrated that our approach is effective for the synthesis of functional magnetic and electric metamaterials with optimal structures. This GA-based optimization-design technique shows great versatility and applicability in the design of functional metamaterials.

Most desktop computer operating systems provide hierarchical folder mechanisms for managing electronic content, therefore hierarchies still dominate digital information management on PCs. Under certain circumstances, the properties of a folder system make it hard to locate and find specific files stored deep within a hierarchy, therefore researchers are currently studying new mechanisms for file storage, organization, and retrieval. Recently, non-exclusive and flat-network tagging mechanisms have gained popularity for managing online information and files. In this paper we discuss memory theories from cognitive psychology and their potential use in the form of tagging mechanisms for storing and retrieving personal information. Next, …
