The Dynamics of Intelligence in the Game Field
Just as men long for freedom, intelligence seeks for uncertainty. Games, which epitomize uncertainty, evolved in their long history to refine uncertainty. This process employed a harmony between skill and chance in games, leading to evolutionary changes in noble uncertainty. Masters who stand at the top of their games seek the ultimate harmony that may exist at the end of the changes. Despite their desire to win, masters occasionally exercise their creativity unconditionally without prejudice. We call this state of mind, that is commonly found among masters, the “model of three masters”. This model reveals three distinct master aspects: the master of winning, the master of playing and the master of understanding. They correspond to each of the three aspects that games possess: competitiveness, entertainment, and metaphor. The model of three masters indicates the existence of various interactions between intelligences of players. We explore it in terms of the “dynamics of intelligence in the field of games”
Games in AI Research - Chips Challenging Champions -
Research using games has demonstrated the possibility of creating high-performance artificial-intelligence systems. Programming computers to play games is but one stage in the development of an understanding of the methods which must be employed for the machine simulation of intellectual behaviour. This research project strives beauty of `Information and Systems' in building a world-championship-caliber shogi program. Moreover, the diversity of decision-making systems and the evolution of intelligence in games will be investigated. 備考
Master Mind
This study examines the way of thinking of masters from the informatics’ point of view. Game informatics is a field where it searches game metric and finding out the meaning of games. Just as men long for freedom, the intellects seek uncertainty. Games, which epitomize uncertainty, have evolved in their long history to optimize uncertainty refinement. This process is a harmony between skill and chance, hence, evolutionary transformation in “noble uncertainty”. Masters who stand on top of their games seek the ultimate harmony which may exist at the end of noble uncertainty’s transitional path. Despite their desire to win, grandmasters seek to find their originality unconditionally without prejudice. I will call this state of mind which is commonly found among grandmasters the “model of three masters”. The true essence in game playing lies in predicting the opponent’s way of thinking. This skill involves “empathy” with opponent’s psyche and is referred as “opponent-model search”. Masters discover great proficiency in opponents and their nature of changes. I would like to propose this transformation of empathy as the “model of player’s cycle”.
Consensus Building and Group Performance in Games
We test N-member simple majority voting for the game ofChess. Several different chess programs were used to make the group. Games were played against the strongest member of the group. We show that the group is stronger than the strongest program. We then aim to answer the research question, under what conditions is N-member simple majority voting stronger than the strongest member?". We performed experiments on various groups. Statistics were gathered about the situations where the group outvoted the group leader. We propose two conditions to answer the research question, firstly group members should be almost equal in strength whilst still showing significant strength difference, and secondly denial percentage of leaders candidate depends on the strength of the members.
Entertainment Sustainability and Morality
In this project, we develop the information technology of evaluating entertainment quantitatively based on the concept of information sciences. Applying this technology, we analyze the negative sides of entertainment in the current e-society. From the analyses, we propose the model plan for the international moral standards for the creators and providers in e-society. We show the theoretical and quantitative method for dealing the social moral problems associated with entertainment environment in e-society. By setting the moral standards in e-society, we contribute the healthy and rightful development of e-society by increasing the morality of entertainment-related business firms.
