The challenge of self-optimization for orthogonal frequency-division multiple-access (OFDMA) interference channels is that users inherently compete harmfully and simultaneous water-filling (WF) would lead to a Pareto-inefficient equilibrium. To overcome this, we first introduce the role of environmental interference derivative in the WF optimization of the interactive OFDMA game and then study ...

Abstract The theory of option games being the combination of two successful theories, namely real options and game theory, has a great potential to applications in many real situations. Although the option games literature is very recent, it has been experimenting a fast growth in the last five years. It considers in the same model, besides the key factors for investment decisions such as uncer...

In this two-part paper, we address the problem of finding the optimal precoding/multiplexing scheme for a set of non-cooperative links sharing the same physical resources, e.g., time and bandwidth. We consider two alternative optimization problems: P.1) the maximization of mutual information on each link, given constraints on the transmit power and spectral mask; and P.2) the maximization of th...

This study attempted to draw a comparison between the age average of Iranian medal winners in Olympic and Asian games and their counterparts from selected countries. The statistical population of the study included Olympic medal winners from the past 100 years and the Iranian who had won medals in 3 rounds of Asian games. The findings indicated that the age average of Iranian medal winners of 3...

this study has aimed to investigate the effect ofthree-dimensional and two-dimensional video games on problem-solving styles ofstudents. statistic society in this study consisted of persian gulf universitystudents in 2016-2017 academic year. and after notification by theproclamation, 45 students were selected voluntarily. at first all 45 students,completed intelligence test and past the experie...

We study competition between wireless devices with incomplete information about their opponents. We model such interactions as Bayesian interference games. Each wireless device selects a power profile over the entire available bandwidth to maximize its data rate (measured via Shannon capacity), which requires mitigating the effect of interference caused by other devices. Such competitive models...

in the paper‎, ‎some new existence theorems of maximal elements for‎ ‎$mathscr{f}_{c,theta}$-mappings and $mathscr{f}_{c,theta}$-majorized mappings are established‎. ‎as applications, ‎some new existence theorems of equilibrium points for‎ ‎one-person games‎, ‎qualitative games and generalized games are obtained‎. ‎our results unify and generalize most known results‎ ‎in recent literature‎.

introduction: computer games have attracted remarkable attentions in general publics with different cultures and their effects are subject of research by cognitive neuroscientists. in the present study, possible effects of the game fifa 2015 on cognitive performance, hormonal levels, and electroencephalographic (eeg) signals were evaluated in young male volunteers. methods: thirty two subjects ...

There has been increasing interest in using game theory to model real-world systems, and in the computation of game-theoretic solution concepts given such a model [14]. The efficiency of game-theoretic computations depends crucially on how games are represented. For multiagent systems with large numbers of agents and actions, the standard normal form game representation is not a practical optio...
