Resilience in Platoons of Cooperative Heterogeneous Vehicles: Self-organization Strategies and Provably-correct Design
Di Liu, Sebastian Mair, Kang Yang +3
This work proposes provably-correct self-organizing strategies for platoons of heterogeneous vehicles. We refer to self-organization as the capability of a platoon to autonomously…
On Lyapunov functions for open Hegselmann-Krause dynamics
Renato Vizuete, Paolo Frasca, Elena Panteley
In this paper, we provide a formulation of an open Hegselmann-Krause (HK) dynamics where agents can join and leave the system during the interactions. We consider a stochastic fram…
Potential detrimental effects of real-time route recommendations in traffic networks
Tommaso Toso, Alain Y. Kibangou, Paolo Frasca
Navigation apps have become pervasive in providing real-time route recommendations to travelers willing to minimize their travel times. However, such technologies introduce new com…
Individual based SIS models on (not so) dense large random networks
Jean-François Delmas, Paolo Frasca, Federica Garin +3
Starting from a stochastic individual-based description of an SIS epidemic spreading on a random network, we study the dynamics when the size of the network tends to infinity.…
Doing data science with platforms crumbs: an investigation into fakes views on YouTube
Maria Castaldo, Paolo Frasca, Tommaso Venturini +1
This paper contributes to the ongoing discussions on the scholarly access to social media data, discussing a case where this access is barred despite its value for understanding an…
Resource allocation in open multi-agent systems: an online optimization analysis
Renato Vizuete, Charles Monnoyer de Galland, Julien M. Hendrickx +2
The resource allocation problem consists of the optimal distribution of a budget between agents in a group. We consider such a problem in the context of open systems, where agents…
Random Coordinate Descent for Resource Allocation in Open Multi-Agent Systems
Charles Monnoyer de Galland, Renato Vizuete, Julien M. Hendrickx +2
We propose a method for analyzing the distributed random coordinate descent algorithm for solving separable resource allocation problems in the context of an open multiagent system…
On Online Attention Dynamics
Maria Castaldo, Paolo Frasca, Tommaso Venturini
This work aims at emphasizing a number of questions that, although crucial since the early days of media studies, have not yet been the object of the empirical and computational st…
Random coordinate descent algorithm for open multi-agent systems with complete topology and homogeneous agents
Charles Monnoyer de Galland, Renato Vizuete, Julien M. Hendrickx +2
We study the convergence in expectation of the Random Coordinate Descent algorithm (RCD) for solving optimal resource allocations problems in open multi-agent systems, i.e., multi-…
Graph structure based Heuristics for Optimal Targeting in Social Networks
M. Bini, P. Frasca, C. Ravazzi +1
We consider a dynamic model for competition in a social network, where two strategic agents have fixed beliefs and the non-strategic/regular agents adjust their states according to…
Generalized solutions to opinion dynamics models with discontinuities
Francesca Ceragioli, Paolo Frasca, Benedetto Piccoli +1
Social dynamics models may present discontinuities in the right-hand side of the dynamics for multiple reasons, including topology changes and quantization. Several concepts of gen…
A Continuation Method for Large-Scale Modeling and Control: from ODEs to PDE, a Round Trip
Denis Nikitin, Carlos Canudas-de-Wit, Paolo Frasca
In this paper we present a continuation method which transforms spatially distributed ODE systems into continuous PDE. We show that this continuation can be performed both for line…
The Rhythms of the Night: increase in online night activity and emotional resilience during the Spring 2020 Covid-19 lockdown
Maria Castaldo, Tommaso Venturini, Paolo Frasca +1
Context. The lockdown orders established in multiple countries in response to the Covid-19 pandemics are arguably one of the most widespread and deepest shock experienced by societ…
On the Influence of Noise in Randomized Consensus Algorithms
Renato Vizuete, Paolo Frasca, Elena Panteley
In this paper we study the influence of additive noise in randomized consensus algorithms. Assuming that the update matrices are symmetric, we derive a closed form expression for t…
The Laplacian Spectrum of Large Graphs Sampled from Graphons
Renato Vizuete, Federica Garin, Paolo Frasca
This paper studies the Laplacian spectrum and the average effective resistance of (large) graphs that are sampled from graphons. Broadly speaking, our main finding is that the Lapl…
Modeling limited attention in opinion dynamics by topological interactions
Francesca Ceragioli, Paolo Frasca, Wilbert Samuel Rossi
This work explores models of opinion dynamics with opinion-dependent connectivity. Our starting point is that individuals have limited capabilities to engage in interactions with t…
Graphon-based sensitivity analysis of SIS epidemics
Renato Vizuete, Paolo Frasca, Federica Garin
In this work, we use the spectral properties of graphons to study stability and sensitivity to noise of deterministic SIS epidemics over large networks. We consider the presence of…
Protecting shared information in networks: a network security game with strategic attacks
Bram de Witte, Paolo Frasca, Bastiaan Overvest +1
A digital security breach, by which confidential information is leaked, does not only affect the agent whose system is infiltrated, but is also detrimental to other agents socially…
Stability of Open Multi-Agent Systems and Applications to Dynamic Consensus
Mauro Franceschelli, Paolo Frasca
In this technical note we consider a class of multi-agent network systems that we refer to as Open Multi-Agent Systems (OMAS): in these multi-agent systems, an indefinite number of…
Stochastic String Stability of Vehicle Platoons via Cooperative Adaptive Cruise Control with Lossy Communication
Francesco Acciani, Paolo Frasca, Geert Heijenk +1
This paper is about obtaining stable vehicle platooning by using Cooperative Adaptive Cruise Control when the communication is unreliable and suffers from message losses. We model…
Functional target controllability of networks: structural properties and efficient algorithms
Christian Commault, Jacob van der Woude, Paolo Frasca
In this paper we consider the problem of controlling a limited number of target nodes of a network. Equivalently, we can see this problem as controlling the target variables of a s…
