Rough Set-Game Theory Information Mining Model Considering Opponents’ Information

In multi-strategy games, the increase in the number of strategies makes it difficult to make a solution. To maintain the competition advantage and obtain maximal profits, one side of the game hopes to predict the opponent’s behavior. Building a model to predict an opponent’s behavior is helpful. In this paper, we propose a rough set-game theory model (RS-GT) considering uncertain information and the opponent’s decision rules. The uncertainty of strategies is obtained based on the rough set method, and an accurate solution is obtained based on game theory from the rough set-game theory model. The players obtain their competitors’ decision rules to predict the opponents’ behavior by mining the information from repeated games in the past. The players determine their strategy to obtain maximum profits by predicting the opponent’s actions, i.e., adopting a first-mover or second-mover strategy to build a favorable situation. The result suggests that the rough set-game theory model helps enterprises avoid unnecessary losses and allows them to obtain greater profits.

Differences between Championships of Football 5-a-Side for Blind People

Research on Football 5-a-side for blind people is usually informative and does not often consider sports performance analysis. This study aimed to verify the existing differences between the 2014 World Championship of Fa5 and the 2016 Paralympic Games, analyzing the action for an effective game, the throws to the goal. For this purpose, a total of 52 matches were analyzed and the statistical analysis unit was all the throws made to the goal during the game (n = 2.227). A descriptive and differential analysis was made between the variables proposed in the study considering the type of competition. The results show the existence of differences between the championships, analyzed explicitly through the variables: Championship phases, Throwing moment, Match status, Starting zone, and Throwing result, as well as the variables Progression type, Throwing zone, Striking situation, Corporal zone, and Striking type. These results highlighted that teams played differently but also set game trends and styles for future competitions.

In Search For Volleyball Entertainment: Impact of New Game Rules on Score and Time-Related Variables

The aim of this research was to analyse the impact of various game structures on score and time-related variables in elite volleyball. A total of 114 male matches and 76 female matches (38 matches for each tournament) were analysed in under-23 world championships. An observational design was implemented to measure match duration, points scored per match and set, set point differences, tournament phase, match balance, and set tendencies in various game structures (set to 21, to 25 or to 15 points) in male and female categories. Standardised differences in mean values showed that a 15-point set game structure led to shortest matches and smallest time variability in match duration, the largest number of points per match, and greatest equality in terms of set score differences in both the male and the female category. The use of various game structures in training may be useful to coaches and conditioning specialists when planning training schemes and sessions, by introducing different game structures to manage volume and intensity in training more effectively. These results may also be useful to local and/or national volleyball federations willing to attract new young players, to promote learning and to render volleyball a fun activity, by implementing S15 at initial stages. In addition, they could be useful to international federations or committees, so as to attract larger audiences and sponsors interested in more appealing matches with high levels of competitiveness and entertainment.

Quando o jogo na escola é bem mais que jogo: possibilidades de intervenção pedagógica no jogo de regras Set Game

Embasado no aporte da Epistemologia Genética, teve como objetivo identificar e analisar as implicações pedagógicas do jogo Set Game para alunos avaliados com dificuldades de aprendizagem e que frequentam a Sala de Apoio à Aprendizagem, um programa oficial do governo do Paraná. De natureza qualitativa, na modalidade de estudo de caso descritivo-interpretativo, o estudo ocorreu em uma escola estadual da cidade de Londrina (PR). Dele participaram dez alunos frequentadores do programa no ano de 2012, em 18 encontros na modalidade de oficina. Os resultados indicaram a importância de oportunizar, por meio do jogo, a construção de processos cognitivos por alunos que frequentam programas de apoio à aprendizagem escolar.

DIFFERENCE-DIFFERENCIAL GAME OF APPROACH AND EVASION IN HILBERT SPACE, I

In this paper the dynamic guidance-to-the-functional set game for conflict controlled differential system with time delay is studied. Fulfillment of conditions of saddle point relative to the right side of the system is not supposed to be. The proof is based on Hilbert space norm.
