A Geometrical Approach to Iterative Isotone Regression
Arnaud Guyader, Nicolas Jégou, Alexander B. Németh +1
In the present paper, we propose and analyze a novel method for estimating a univariate regression function of bounded variation. The underpinning idea is to combine two classical…
Analysis of Cognitive Radio Scenes Based on Non-cooperative Game Theoretical Modelling
Ligia Cremene, Dumitru Dumitrescu
A noncooperative game theoretical approach for analysing opportunistic spectrum access (OSA) in cognitive radio (CR) environments is proposed. New concepts from game theory are app…
Cognitive Radio Simultaneous Spectrum Access/ One-shot Game Modelling
Ligia C. Cremene, D. Dumitrescu, Reka Nagy +1
The aim of this work is to asses simultaneous spectrum access situations that may occur in Cognitive Radio (CR) environments. The approach is that of one shot, noncooperative games…
Game Theoretical Modelling for Dynamic Spectrum Access in TV Whitespace
Ligia C. Cremene, D. Dumitrescu, Reka Nagy +1
In order to assess TV whitespace access scenarios, three oligopoly game models are considered and reformulated in terms of radio access: Cournot, Stackelberg, and Bertrand. Besides…
A hybrid ACO approach to the Matrix Bandwidth Minimization Problem
Camelia-M. Pintea, Camelia Chira, Gloria-C. Crisan
The evolution of the human society raises more and more difficult endeavors. For some of the real-life problems, the computing time-restriction enhances their complexity. The Matri…
The Chaos Within Sudoku
Maria Ercsey-Ravasz, Zoltan Toroczkai
The mathematical structure of the widely popular Sudoku puzzles is akin to typical hard constraint satisfaction problems that lie at the heart of many applications, including prote…
