Optimal Control of Behavioral-Feedback SIR Epidemic Model
Martina Alutto, Leonardo Cianfanelli, Giacomo Como +2
We consider a behavioral-feedback SIR epidemic model, in which the infection rate depends in feedback on the fractions of susceptible and infected agents. Contrary to the classic S…
Continuous-Time Distributed Learning for Collective Wisdom Maximization
Luka Baković, Giacomo Como, Fabio Fagnani +2
Motivated by the well established idea that collective wisdom is greater than that of an individual, we propose a novel learning dynamics as a sort of companion to the Abelson mode…
Controlling a Social Network of Individuals with Coevolving Actions and Opinions
Roberta Raineri, Mengbin Ye, Lorenzo Zino
In this paper, we consider a population of individuals who have actions and opinions, which coevolve, mutually influencing one another on a complex network structure. In particular…
An invariance principle based concentration result for large-scale stochastic pairwise interaction network systems
Giacomo Como, Fabio Fagnani, Sandro Zampieri
We study stochastic pairwise interaction network systems whereby a finite population of agents, identified with the nodes of a graph, update their states in response to both indivi…
Nash equilibria of the pay-as-bid auction with K-Lipschitz supply functions
Martina Vanelli, Giacomo Como, Fabio Fagnani
We model a system of n asymmetric firms selling a homogeneous good in a common market through a pay-as-bid auction. Every producer chooses as its strategy a supply function returni…
Imitation dynamics in population games on community networks
Giacomo Como, Fabio Fagnani, Lorenzo Zino
We study the asymptotic behavior of deterministic, continuous-time imitation dynamics for population games over networks. The basic assumption of this learning mechanism -- encompa…
Fast Spread in Controlled Evolutionary Dynamics
Lorenzo Zino, Giacomo Como, Fabio Fagnani
We study the spread of a novel state in a network, in the presence of an exogenous control. The considered controlled evolutionary dynamics is a non-homogeneous Markov process that…
Finite-time influence systems and the Wisdom of Crowd effect
Francesco Bullo, Fabio Fagnani, Barbara Franci
Recent contributions have studied how an influence system may affect the wisdom of crowd phenomenon. In the so-called naive learning setting, a crowd of individuals holds opinions…
On stochastic imitation dynamics in large-scale networks
Lorenzo Zino, Giacomo Como, Fabio Fagnani
We consider a broad class of stochastic imitation dynamics over networks, encompassing several well known learning models such as the replicator dynamics. In the considered models,…
On imitation dynamics in potential population games
Lorenzo Zino, Giacomo Como, Fabio Fagnani
Imitation dynamics for population games are studied and their asymptotic properties analyzed. In the considered class of imitation dynamics - that encompass the replicator equation…
From local averaging to emergent global behaviors: the fundamental role of network interconnections
Giacomo Como, Fabio Fagnani
Distributed averaging is one of the simplest and most studied network dynamics. Its applications range from cooperative inference in sensor networks, to robot formation, to opinion…
The robustness of democratic consensus
Fabio Fagnani, Jean-Charles Delvenne
In linear models of consensus dynamics, the state of the various agents converges to a value which is a convex combination of the agents' initial states. We call it democratic if i…
Limited benefit of cooperation in distributed relative localization
Wilbert Samuel Rossi, Paolo Frasca, Fabio Fagnani
Important applications in robotic and sensor networks require distributed algorithms to solve the so-called relative localization problem: a node-indexed vector has to be reconstru…
