Despite tremendous popularity of video games, there have been concerns about their detrimental effects on children. The game rating systems were developed to assist parents in monitoring their children’s gaming experiences. This paper explores how parents in Iran, as a society without established media rating systems, control their children’s gaming experiences. Mixed methods of semi-structured...

Teaching Games for Understanding (TGfU) was introduced in the 1980s and brought a new focus to the teaching of games. The participant is placed in a game situation where problem solving, decision-making and tactical understanding are vital ingredients. Another key ingredient is enjoyment to enhance and promote physical activity. In order to understand the factors that impact on the teaching of ...

In this paper, we propose automatic generation mechanism of learning games based on a card game model that is a structured representation of a set of concepts within a card game and the relationships between those concepts. An authoring system that generates various types of computer-based learning games based on the card game model is also introduced. We confirmed that the system could generat...

We consider a propositional dynamic logic whose programs are regular expressions over game strategy pairs. At the atomic level, these are finite extensive form game trees with structured strategy specifications, whereby a player’s strategy may depend on properties of the opponent’s strategy. The advantage of imposing structure not merely on games or on strategies but on game strategy pairs, is ...

Population structure induced by both spatial embedding and more general networks of interaction, such as model social networks, have been shown to have a fundamental effect on the dynamics and outcome of evolutionary games. These effects have, however, proved to be sensitive to the details of the underlying topology and dynamics. Here we introduce a minimal population structure that is describe...

We propose an asymmetric negotiation strategy to investigate the influence of high-degree agents on the agreement dynamics in a structured language game, the naming game. We introduce a model parameter, which governs the frequency of high-degree agents acting as speakers in communication. It is found that there exists an optimal value of the parameter that induces the fastest convergence to a g...

Spatial structure greatly affects the evolution of cooperation. While in two-player games the condition for cooperation to evolve depends on a single structure coefficient, in multiplayer games the condition might depend on several structure coefficients, making it difficult to compare different population structures. We propose a solution to this issue by introducing two simple ways of orderin...

1 Summary We discuss strategies in non-zero sum games of perfect information on graphs. The study of non-zero sum games on graphs is motivated by the advent of computational tasks on the worldwide web and related security requirements which have thrown up many interesting areas of interaction between game theory and computer science. For example, signing contracts on the web requires interactio...

We describe a fairly general model for the evolutionary dynamics in a sub-divided (or deme structured) population with migration and mutation. The number and size of demes are finite and fixed. The fitness of each individual is determined by pairwise interactions with other members of the same deme. The dynamics within demes can be modeled according to a broad range of evolutionary processes. W...

We provide the first fully polynomial time approximation scheme (FPTAS) for computing an approximate mixed-strategy Nash equilibrium in tree-structured graphical multi-hypermatrix games (GMhGs). GMhGs are generalizations of normal-form games, graphical games, graphical polymatrix games, and hypergraphical games. Computing an exact mixed-strategy Nash equilibria in graphical polymatrix games is ...
