Classical Game

Automata theory plays an important role in various areas especially in game design. This paper describes the concept of automata theory in designing one of the most popular classical game which is Hangman. In this study, we focused on a game called Hangaroo, which implemented the same concept as in Hangman game. We studied and discussed the combination of automata and game theory that can be considered in order to design the game. As a result, we found that, automata theory is the fundamental access in designing and developing Games.

Game Performance

Players sit around a table. A group of adventurers pause in their pursuit of escape. Stunned, they stare at the die that just rolled poorly, resulting in the loss of a dear friend, his throat ripped out because they could not save him. The players mourn the death of a fictional character who only ever existed within the game. Dungeons & Dragons (D&D) is a popular role-playing game illustrating the interconnectedness of drama, performance, and games. My presentation will examine this relationship, identifying factors from gameplay that suggest how performance fosters success in D&D for both actual players and fictional characters. Research into dramatic theory and game theory reveals how interdisciplinary concepts such as the “magic circle”, the “lusory attitude”, and uncertainty can apply to elements of D&D (Salen and Zimmerman, Suits, Costikyan). Data collected from in-person observation of D&D sessions, coding participants’ behaviour, and watching for instances of performance (e.g. voice change, pronoun switches, or mimetic gesture), has been combined with theoretical research to determine elements that better facilitate success in the game/campaign. These elements range from emotional situations that provoke players, to forms of invitations encouraging participation (Isbister, White). I have discovered that while in theatre performance acts as a vehicle for story, in D&D the story acts as a vehicle for performance. The in-game performance often facilitates fun between players, as well as leading them to success in the game, so a campaign that maximizes theatricality will not only result in more fun, but also more success.

Classical Game

Based on the perspective of the quantum game, this paper explores when the online direct sales channel takes the free-riding behavior after the retail channel provides high-quality experience and services and how the dual-channel supply chain establishes a commodity pricing strategy. The retailer’s selling price follows a decreasing function of the free-riding behavior coefficient. while the online direct selling price does an increasing function of the free-riding behavior coefficient. Under centralized decision-making, there is no quantum entanglement, so the quantum game solution is consistent with the classical game solution. Under decentralized decision-making, the optimal price and profit of the quantum game are higher than those of the classical game when the quantum entanglement degree is greater than zero. When the quantum entanglement tends to be infinite, the optimal price of the quantum game finally remains in convergence. The quantum game theory is a more optimal decision-making method than the classical game theory.

Adaptation Model

Classical game theory analyses strategic interactions under extreme idealisations. It assumes cognitively unconstrained players with common knowledge concerning game forms, preferences, and rationality. Such ideal theory is highly relevant for human self-understanding as a rational being or what Selten called ‘rationology’. Yet, ideal theory is highly irrelevant for real actors who are in Selten’s sense boundedly rational. Starting from essential features of real bargaining problems, elements of Selten’s ‘micro-psychological’ and Raiffa’s ‘telescopic’ behavioural bargaining theory are introduced. From this, an outline of a workable rationality approach to bargaining emerges. It suggests relying on telescopic elements from Raiffa’s model to provide general outcome orientation and on insights from Selten’s aspiration adaptation model of individual decision making to develop process-sensitive action advice. A bird’s eye view of a prominent recent case of ‘bargaining in the shadow of the courts’ shows a surprisingly good fit of outcomes with the implications of Raiffa’s telescopic approach while remaining compatible with a Seltenian process. Though due to a lack of specific information because the micro-foundations for the telescopic theory cannot be provided, it is at least clear how further case studies and experiments might be put to work here.

Classical Game Theory

In game theory, two or more parties need to make decisions with fully or partially conflicting objectives. In situations where reaching a more favourable outcome depends upon cooperation between the two conflicting parties, some of the mental and subjective attitudes of the decision makers must be considered. While the decision to cooperate with others bears some risks due to uncertainty and loss of control, not cooperating means giving up potential benefits. In practice, decisions must be made under risk, uncertainty, and incomplete or fuzzy information. Because it is able to work well with vague, ambiguous, imprecise, noisy or missing information, the fuzzy approach is effective for modeling such multicriteria conflicting situations. The well-known game of Prisoner's Dilemma, which reflects a basic situation in which one must decide whether to cooperate or not with a competitor, is systematically solved using a fuzzy approach. The fuzzy procedure is used to incorporate some of the subjective attitudes of the decision makers that are difficult to model using classical game theory. Furthermore, it permits researchers to consider the subjective attitudes of the decision makers and make better decisions in subjective, uncertain, and risky situations.

Classical Game Theory

A symmetric game consists of a set of pure strategies indexed by {0, …, n} and a real payoff matrix (aij). When two players choose strategies i and j the payoffs are aij and aji to the i-player and j-player respectively. In classical game theory of Von Neumann and Morgenstern [16] the payoffs are measured in units of utility, i.e., desirability, or in units of some desirable good, e.g. money. The problem of game theory is that of a rational player who seeks to choose a strategy or mixture of strategies which will maximize his return. In evolutionary game theory of Maynard Smith and Price [13] we look at large populations of game players. Each player's opponents are selected randomly from the population, and no information about the opponent is available to the player. For each one the choice of strategy is a fixed inherited characteristic.

This study investigates how the use of visual facilitation and representations, e.g. visualisations and video productions, combined with peer‑feedback sessions can create exploratory approaches to game design in online teaching. The article analyses an iterative game development process in an online learning context. The empirical data is primarily based on an explorative case study of “Games for change”; a course held in 2018 in which master students from the international Nordic Visual Studies and Art Education (NoVA) design games that address issues in society. Throughout the course, the students from universities in Finland, Sweden and Denmark engaged in a cross‑cultural collaboration across campuses. The purpose of the study was to explore how to establish an online space for joint design inquiry in the context of ‘games for change’ across time and space as well as cultural and professional barriers. The data used for analysis includes teaching observations, videos of play sessions, photos and visual representations, students’ reflection papers and students’ written and oral evaluations after completion of the course. The analysis is based on different problem‑based learning (PBL) activities; lectures, video instructions, presentation‑ and feedback sessions, reflexive exercises and students’ self‑directed design and learning processes in groups. As part of the game course, teachers presented game theory and exercises through videos and visualisations to support the students’ iterative game design processes. The analysis of the PBL activities shows that teachers’ video instructions relating theoretical game concepts to the students’ actual group work supported the introduction to the game field as well as their design processes. The balance between the value of video instructions with specific feedback and teachers’ time for preparation is a relevant issue for further exploration in online teaching. Moreover, findings show that the students’ visualisations and video productions exemplifying game situations created a visible reference point for further discussions in feedback sessions across campuses, which guided game development. Thus, the combination of inquiry approaches, critical game theory and design processes combined with students’ visualisations and video productions provides interesting connections for bridging gaps between cultures and professions, e.g. in art and games. By the rich and visual descriptions of PBL activities, student work and reflective evaluations, the exploratory case study can function as inspiration for applying similar approaches to new local contexts in higher education.

Classical Game Theory

Classical game theory is an important field with a long tradition of useful results. Recently, the quantum versions of classical games, such as the prisoner’s dilemma (PD), have attracted a lot of attention. This game variant can be considered as a specific type of game where the player’s actions and strategies are formed using notions from quantum computation. Similarly, state machines, and specifically finite automata, have also been under constant and thorough study for plenty of reasons. The quantum analogues of these abstract machines, like the quantum finite automata, have been studied extensively. In this work, we examine well-known conditional strategies that have been studied within the framework of the classical repeated PD game. Then, we try to associate these strategies to proper quantum finite automata that receive them as inputs and recognize them with a probability of 1, achieving some interesting results. We also study the quantum version of PD under the Eisert–Wilkens–Lewenstein scheme, proposing a novel conditional strategy for the repeated version of this game.
