Computing an equilibrium of an extensive form game of incomplete information is a fundamental problem in computational game theory, but current techniques do not scale to large games. To address this, we introduce the ordered game isomorphism and the related ordered game isomorphic abstraction transformation. For an n-player sequential game of incomplete information with observable actions and ...

a {em roman dominating function} on a graph $g = (v ,e)$ is a function $f : vlongrightarrow {0, 1, 2}$ satisfying the condition that every vertex $v$ for which $f (v) = 0$ is adjacent to at least one vertex $u$ for which $f (u) = 2$. the {em weight} of a roman dominating function is the value $w(f)=sum_{vin v}f(v)$. the roman domination number of a graph $g$, denoted by $gamma_r(g)$, equals the...

Recent interest in interactive video game technology (IVGT) has spurred the notion that exercise from this technology may have meaningful physiological and psychological benefits for children and adolescents. The purpose of this study was to examine the short-term psychological effects of interactive video game exercise in young adults and whether IVGT participation was capable of improving moo...

1. We proved that in any game for which there exists a jointly-differentially private algorithm for computing an approximate Nash equilibrium, there exists a corresponding mediated game in which “good behavior” (using the mediator, truthfully reporting your type to it, and then faithfully following its suggestion) forms an ex-post Nash equilibrium, and that the resulting play forms a Nash equil...

Introduction: Aging is associated with biological changes and may lead to various cognitive behavioural disorders such as insomnia and depression. Non-pharmacological interventions with pharmacological therapies would be effective, economical, and safe. The present study compared the effect of muscle strength-range of movement (MSROM) training and digital game on insomnia and depression disorde...

the aim of the present study was to investigate the effect of an official basketball game and its result on serum testosterone and cortisol responses as well as a possible difference in these hormones between fixed and reserved players. for this purpose, two teams were purposefully selected from semi-final games of tehran first clubs. the blood samples of 22 female players (mean age: 20 years, ...

Long have studies attempted to bridge the gap between perception and reality for video games attributes. This study highlights the relationship between what a player perceives about certain game attributes (Challenge, Control and Mystery) and how those elements are actually portrayed in the game. We measured user perception with a post-game questionnaire and compared that to the answers of poin...

We introduce the concept of a TUU-game, a transferable utility game with uncertainty. In a TUU-game there is uncertainty regarding the payoffs of coalitions. One out of a finite number of states of nature materializes and conditional on the state, the players are involved in a particular transferable utility game. We consider the case without ex ante commitment possibilities and propose the Wea...

BACKGROUND "Michael's game" is a card game which aims at familiarizing healthcare professionals and patients with cognitive behavioral therapy of psychotic symptoms. This naturalistic study tests the feasibility and the impact of the intervention in various naturalistic settings. METHOD Fifty five patients were recruited in seven centers. They were assessed in pre and post-test with the Peter...
