A simple model of knowledge percolation
Franco Bagnoli, Guido de Bonfioli Cavalcabo'
We investigate how knowledge percolates and clusters in a given knowledge space. We introduce a simple model of knowledge organization in which each contribution spans a certain nu…
Intransitiveness in the Penney Game and in Random Walks on rings, networks, communities and cities
Alberto Baldi, Franco Bagnoli
The concept of intransitiveness for games, which is the condition for which there is no first-player winning strategy can arise surprisingly, as happens in the Penney game, an exte…
Humans make best use of social heuristics when confronting hard problems in large groups
Federica Stefanelli, Enrico Imbimbo, Daniele Vilone +3
We report the results of a game-theoretic experiment with human players who solve the problems of increasing complexity by cooperating in groups of increasing size. Our experimenta…
A Self-Organized Method for Computing the Epidemic Threshold in Computer Networks
Franco Bagnoli, Emanuele Bellini, Emanuele Massaro
In many cases, tainted information in a computer network can spread in a way similar to an epidemics in the human world. On the other had, information processing paths are often re…
Control of multidimensional systems on complex network
Giulia Cencetti, Franco Bagnoli, Giorgio Battistelli +2
Multidimensional systems coupled via complex networks are widespread in nature and thus frequently invoked for a large plethora of interesting applications. From ecology to physics…
The second will be first: competition on directed networks
Giulia Cencetti, Franco Bagnoli, Francesca Di Patti +1
Multiple sinks competition is investigated for a walker diffusing on directed complex networks. The asymmetry of the imposed spatial support makes the system non transitive. As a c…
Epidemic spreading and risk perception in multiplex networks: a self-organized percolation method
Franco Bagnoli, Emanuele Massaro
In this paper we study the interplay between epidemic spreading and risk perception on multiplex networks. The basic idea is that the effective infection probability is affected by…
Hierarchical community structure in complex (social) networks
Emanuele Massaro, Franco Bagnoli
The investigation of community structure in networks is a task of great importance in many disciplines, namely physics, sociology, biology and computer science where systems are of…
Application of a cognitive-inspired algorithm for detecting communities in mobility networks
Emanuele Massaro, Lorenzo Valerio, Andrea Guazzini +2
The emergence and the global adaptation of mobile devices has influenced human interactions at the individual, community, and social levels leading to the so called Cyber-Physical…
Modeling Risk Perception in Networks with Community Structure
Franco Bagnoli, Daniel Borkmann, Andrea Guazzini +2
We study the influence of global, local and community-level risk perception on the extinction probability of a disease in several models of social networks. In particular, we study…
Cognitive network structure: an experimental study
Andrea Guazzini, Daniele Vilone, Franco Bagnoli +2
In this paper we present first experimental results about a small group of people exchanging private and public messages in a virtual community. Our goal is the study of the cognit…
Information dynamics algorithm for detecting communities in networks
E. Massaro, A. Guazzini, F. Bagnoli +1
The problem of community detection is relevant in many scientific disciplines, from social science to statistical physics. Given the impact of community detection in many areas, su…
Impact of network structure on a model of diffusion and competitive interaction
V. Nicosia, F. Bagnoli, V. Latora
We consider a model in which agents of different species move over a complex network, are subject to reproduction and compete for resources. The complementary roles of competition…
Smallworld bifurcations in an opinion model
Franco Bagnoli, Graziano Barnabei, Raul Rechtman
We study a cellular automaton opinion formation model of Ising type, with antiferromagnetic pair interactions modeling anticonformism, and ferromagnetic plaquette terms modeling th…
Birth and Death in a Continuous Opinion Dynamics Model. The consensus case
Timoteo Carletti, Duccio Fanelli, Alessio Guarino +2
We here discuss the process of opinion formation in an open community where agents are made to interact and consequently update their beliefs. New actors (birth) are assumed to rep…
Opinion Dynamics in an Open Community
Timoteo Carletti, Duccio Fanelli, Alessio Guarino +2
We here discuss the process of opinion formation in an open community where agents are made to interact and consequently update their beliefs. New actors (birth) are assumed to rep…
Dynamical affinity in opinion dynamics modelling
Franco Bagnoli, Timoteo Carletti, Duccio Fanelli +2
We here propose a model to simulate the process of opinion formation, which accounts for the mutual affinity between interacting agents. Opinion and affinity evolve self-consistent…
