The phenomena of cooperation in animal and human society are ubiquitous, but the selfish outcome that no player contributes to the public good will lead to the "tragedy of the commons". The recent research shows that high punishment can improve the cooperation of the population. In this paper, we introduce a punishment mechanism into spatial voluntary public goods games with every individual only knowing his own payoff in each round. Using the self-adjusting rules, we find that the different cost for punishment can lead to different effects on the voluntary public goods games. Especially, when the cost for punishment is decreased, a higher contribution region will appear in the case of low r value. It means even for the low r value, individuals can form the contributing groups in large quantities to produce a more efficient outcome than that in moderate r value. In addition, we also find the players' memory can have effects on the average outcome of the population.

The last few decades have seen a phenomenal increase in the quality, diversity and pervasiveness of computer games. The worldwide computer games market is estimated to be worth around USD 21bn annually, and is predicted to continue to grow rapidly. This paper reviews some of the recent developments in applying computational intelligence （CI） methods to games, points out some of the potential pitfalls, and suggests some fruitful directions for future research.

This research focuses on the description of selected mathematics-related games in Anaang, South-Nigeria. Nigeria is a pluri-linguistics and pluri-ethnic society with a rich multicultural heritage. The nation has three major linguistic groups, and over four hundred non-major linguistic communities. Anaang is a non-major linguistic society. Interest in the development of the Anaang language is quite recent, dating back to 1980, though since then there have been more publications about its linguistics than about its culture. The culture of Anaang, as well as its literature exists dominantly in oral form. This affects the intergenerational transmission of rich cultural heritage, and could eventually lead to its collapse. Part of this cultural heritage includes games, which constitute one of the many interesting aspects of African verbal art. As we believe, it is pertinent to develop such an interesting genre for both outdoor and indoor activities. The major aim of this research article is to relate the relevance of mathematics ideas(mathematics games) to cultural development in Anaang, vis-a-vis Africa, and to harness the relevant activities of the Anaang culture, which are encoded in games with mathematics concepts. This work is purely descriptive and tends to employ diagrammatic illustrations to provide insights into the activities of the various mathematics games in Anaang. Data for the work is based on selected games used by children and adults for indoor/outdoor recreation. Since children assimilate numbers, words, sentences, and figures with ease in short songs/rhymes and games, this paper proposes that verses of mathematics games should be developed, documented, preserved and used for the learning of some aspects of mathematics like counting, numeration, calculation, fractions, addition, subtractions, division, ratios, Highest Common Factor(HCF), Lowest Common Multiple(LCM), etc, as well as culture. This paper is relevant in the understanding of the interface bet

The current industrial society has imposed on the Olympic athletes role models to play, but at the same time provided them with neither necessary means to reach such roles nor a proper social environment to play such roles. The main reason for this dilemma is the materialism oriented social value judgment,which has made it unavoidable for the athletes being manipulated. With the arriving of a post industrial society in the 21st century athletes may take an active part not only in the sport arena but also in decision makings of the Olympic affairs. This developmental trend is based on the shift of the dominant social value towards the humanism orientation, the demand of future development of sport, the educational reform associated to the formation of multimedia network , and the democratization in the Olympic Movement.
