Self-organization of nodes in mobile ad hoc networks using evolutionary games and genetic algorithms

Journal of Advanced Research, 2011
In this paper, we present a distributed and scalable evolutionary game played by autonomous mobile ad hoc network (MANET) nodes to place themselves uniformly over a dynamically changing environment without a centralized controller.

The Naming Game in Social Networks: Community Formation and Consensus Engineering

, 2010
We study the dynamics of the Naming Game [Baronchelli et al., (2006) J. Stat. Mech.: Theory Exp. P06014] in empirical social networks. This stylized agent-based model captures essential features of agreement dynamics in a network of autonomous agents ...

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials

Advanced Materials, EarlyView.
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Alignment, Rising, Sticking, and Phototaxis: Modulating the Behavior of Hematite Micropeanuts

Advanced Materials Interfaces, EarlyView.
Although a rich variety of behaviors, such as rising and phototaxis, are observed with light‐activated semiconductor microparticles, the experimental conditions under which such behaviors occur have not been elucidated. In this study, pH, fuel concentration, and light intensity are varied, revealing diverse behaviors of hematite microparticles.

Studies in the Theory of Quantum Games [PDF]

arXiv, 2005
Theory of quantum games is a new area of investigation that has gone through rapid development during the last few years. Initial motivation for playing games, in the quantum world, comes from the possibility of re-formulating quantum communication protocols, and algorithms, in terms of games between quantum and classical players.

A Complex Network and Evolutionary Game Theory Framework for 6G Function Placement

IEEE Open Journal of the Communications Society
Towards 6G, a key challenge lies in the placement of virtual network functions on physical resources. This becomes complex due to the dynamic nature of mobile environments, making the design a major point of research.

Is altruism evolutionarily stable ? [PDF]

We develop an evolutionary approach to explain altruistic preferences. Given their preferences, individuals interact rationally with each other. By comparing the success of players with different preferences, we investigate whether evolution favors ...

Fabrication of Ultra‐Thick Masks for X‐Ray Phase Contrast Imaging at Higher Energy

Advanced Materials Interfaces, EarlyView.
This work shows a fabrication route to 500 µm thick X‐ray masks the thickest ever reported in the literature combining dynamic optimization of etching parameters and superconformal bismuth‐mediated gold filling. Their use in an Edge Illunomination set‐up showed their higher phase sensitivity at higher energies compared to thinner masks, especially for ...

Strategic Teaching and Learning in Games [PDF]

arXiv, 2015
It is known that there are uncoupled learning heuristics leading to Nash equilibrium in all finite games. Why should players use such learning heuristics and where could they come from? We show that there is no uncoupled learning heuristic leading to Nash equilibrium in all finite games that a player has an incentive to adopt, that would be ...
