Rating players in games with real-valued outcomes
نویسندگان
چکیده
Game-theoretic models typically associate outcomes with real valued utilities, and rational agents are expected to maximize their expected utility. Currently fielded agent rating systems, which aim to order a population of agents by strength, focus exclusively on games with discrete outcomes, e.g., win-loss in two-agent settings or an ordering in the multi-agent setting. These rating systems are not well-suited for domains where the absolute magnitude of utility rather than just the relative value is important. We introduce the problem of rating agents in games with real-valued outcomes and survey applicable existing techniques for rating agents in this setting. We then propose a novel rating system and an extension for all of these rating systems to games with more than two agents, showing experimentally the advantages of our proposed system.

An interval-valued programming approach to matrix games with payoffs of triangular intuitionistic fuzzy numbers
The purpose of this paper is to develop a methodology for solving a new type of matrix games in which payoffs are expressed with triangular intuitionistic fuzzy numbers (TIFNs). In this methodology, the concept of solutions for matrix games with payoffs of TIFNs is introduced. A pair of auxiliary intuitionistic fuzzy programming models for players are established to determine optimal strategies...
متن کاملA review on symmetric games: theory, comparison and applications
Game theory models decision makers' behaviors in strategic situations. Since the structures of games are different, behavior and preferences of the players are different in various types of game. This paper reviews various situations of games. Here, characteristics of some common games are discussed and compared. Specifically, we focus on a group of games called symmetric games including Prison...
متن کاملRobust Opponent Modeling in Real-Time Strategy Games using Bayesian Networks
Opponent modeling is a key challenge in Real-Time Strategy (RTS) games as the environment is adversarial in these games, and the player cannot predict the future actions of her opponent. Additionally, the environment is partially observable due to the fog of war. In this paper, we propose an opponent model which is robust to the observation noise existing due to the fog of war. In order to cope...
متن کاملDiscrete bidding games
We study variations on combinatorial games in which, instead of alternating moves, the players bid with discrete bidding chips for the right to determine who moves next. We consider both symmetric and partisan games, and explore differences between discrete bidding games and Richman games, which allow real-valued bidding. Unlike Richman games, discrete bidding game variations of many familiar g...
متن کاملDynamic system of strategic games
Maybe an event can't be modeled completely through one game but there is more chance with several games. With emphasis on players' rationality, we present new properties of strategic games, which result in production of other games. Here, a new attitude to modeling will be presented in game theory as dynamic system of strategic games and its some applications such as analysis of the clash betwe...
