Designing an Evolutionary Strategizing Machine for Game Playing and Beyond

We have shown that genetically programming game players, after having imbued the evolutionary process with human intelligence, produces human-competitive strategies for three games: backgammon, chess endgames, and robocode (tank-fight simulation). Evolved game players are able to hold their own - and often win - against human or human-based competitors. This paper has a twofold objective: first, to review our results of applying genetic programming in the domain of games; second, to formulate the merits of genetic programming in acting as a tool for developing strategies in general, and to discuss the possible design of a strategizing machine.     

改进的三方扑克协议

扑克协议是指在不需要第三方参与的情况下实现公平的扑克游戏。而常规的三方扑克协议在没有第四方的参与下若有两方联合起来则就可以实现不公平的扑克游戏,针对这一问题,提出一种改进的三方扑克协议,该协议通过第一次循环来实现所有的牌手使用自己的公钥对54张扑克进行加密,然后通过第二次循环来实现所有的牌手取得自己的牌并对上家牌手的牌进行逐次解密,再通过第三次循环来实现解密所有的牌。为验证该算法的性能,将改进协议与常规协议进行了对比实验,实验结果表明,改进协议有效地解决了公平性的问题。     

Cray/Blitz—1984 chess champion

The chess program “Cray Blitz” is the current World Computer Chess Champion and North American Computer Chess Champion (ACM). The program has also played in human chess tournaments and is a chess master. At speed chess, where its ability to perform very accurate analysis is particularly important, it has maintained a performance rating of over 2600 for the past two years. This indicates that at speed chess, the program is one of the top players, electronic or human, in the world. It is currently running on a Cray XMP-48 computer system and has been designed around the parallelism that the XMP architecture provides.     

On-Line E-Wallet System with Decentralized Credential Keepers

We propose a generalization of the architecture of an electronic wallet, as first developed in the seminal European research project CAFE. With this model you can leave most of the content of your electronic wallet at the security of your residential electronic keeper, while roaming with your favorite mobile terminals. Emerging mobile handsets with both short range Bluetooth and cellular GPRS communications provide a sufficient communication platform for this electronic wallet architecture. However, new security requirements must be addressed, and new threats of attack must be carefully analyzed and met with appropriate security protocols. The proposed approach is fundamentally distinct from the remote wallet proposals, in that it protects important user requirements and takes a multiparty security approach using a fully decentralized architecture. Technically, the user remains in control of the input/output and usage of his credentials, likely carried by smart cards. At the same time, the model provides a solution to the pressing practical problem of the multitude of special-branded cards the user has to carry and sort. Currently used magnetic stripe and chip cards with applications such as debit and credit transactions are easily included within the architecture with minor enhancement to these legacy systems and their functionality. We show in this paper how an account-based payment system can be solved with the proposed architecture. Our claim is that users achieve payment mobility and independence of both terminals and payment service providers while maintaining secure access to their payment authorization credentials.     

A reconfigurable multilevel parallel texture cache memory with75-GB/s parallel cache replacement bandwidth

Recently, the level of realism in PC graphics applications has been approaching that of high-end graphics workstations, necessitating a more sophisticated texture data cache memory to overcome the finite bandwidth of the AGP or PCI bus. This paper proposes a multilevel parallel texture cache memory to reduce the required data bandwidth on the AGP or PCI bus and to accelerate the operations of parallel graphics pipelines in PC graphics cards. The proposed cache memory is fabricated by 0.16-μm DRAM-based SOC technology. It is composed of four components: an 8-MB DRAM L2 cache, 8-way parallel SRAM L1 caches, pipelined texture data filters, and a serial-to-parallel loader. For high-speed parallel L1 cache data replacement, the internal bus bandwidth has been maximized up to 75 GB/s with a newly proposed hidden double data transfer scheme. In addition, the cache memory has a reconfigurable architecture in its line size for optimal caching performance in various graphics applications from three-dimensional (3-D) games to high-quality 3-D movies
