Boltzmann-type equations for multi-agent systems with label switching

N Loy, A Tosin - arXiv preprint arXiv:2006.15550, 2020 - arxiv.org
In this paper, we propose a Boltzmann-type kinetic description of mass-varying interacting
multi-agent systems. Our agents are characterised by a microscopic state, which changes …

Kinetic description of swarming dynamics with topological interaction and transient leaders

G Albi, F Ferrarese - Multiscale Modeling & Simulation, 2024 - SIAM
In this paper, we present a model describing the collective motion of birds. The model
introduces spontaneous changes in direction which are initialized by few agents, here …

Quantitative propagation of chaos in a bimolecular chemical reaction-diffusion model

TS Lim, Y Lu, JH Nolen - SIAM Journal on Mathematical Analysis, 2020 - SIAM
We study a stochastic system of N interacting particles which models bimolecular chemical
reaction-diffusion. In this model, each particle i carries two attributes: the spatial location …

B Piccoli, F Rossi - Crowd Dynamics, Volume 1: Theory, Models, and …, 2018 - Springer
This chapter revises some modeling, analysis, and simulation contributions for crowd
dynamics using time-evolving measures. Two key features are strictly related to the use of …

Kinetic based optimization enhanced by genetic dynamics

G Albi, F Ferrarese, C Totzeck - arXiv preprint arXiv:2306.09199, 2023 - arxiv.org
We propose and analyse a variant of the recently introduced kinetic based optimization
method that incorporates ideas like survival-of-the-fittest and mutation strategies well-known …

Mean-field selective optimal control via transient leadership

G Albi, S Almi, M Morandotti, F Solombrino - Applied Mathematics & …, 2022 - Springer
A mean-field selective optimal control problem of multipopulation dynamics via transient
leadership is considered. The agents in the system are described by their spatial position …

Mean-field analysis of multipopulation dynamics with label switching

M Morandotti, F Solombrino - SIAM Journal on Mathematical Analysis, 2020 - SIAM
The mean-field analysis of a multipopulation agent-based model is performed. The model
couples a particle dynamics driven by a nonlocal velocity with a Markov-type jump process …

A Wasserstein norm for signed measures, with application to nonlocal transport equation with source term

B Piccoli, F Rossi, M Tournus - arXiv preprint arXiv:1910.05105, 2019 - arxiv.org
We introduce the optimal transportation interpretation of the Kantorovich norm on thespace
of signed Radon measures with finite mass, based on a generalized Wasserstein …

E Cristiani, N Loy, M Menci, A Tosin - Mathematics and Computers in …, 2025 - Elsevier
In this paper, we derive a kinetic description of swarming particle dynamics in an interacting
multi-agent system featuring emerging leaders and followers. Agents are classically …

A multi-step Lagrangian scheme for spatially inhomogeneous evolutionary games

S Almi, M Morandotti, F Solombrino - Journal of Evolution Equations, 2021 - Springer
A multi-step Lagrangian scheme at discrete times is proposed for the approximation of a
nonlinear continuity equation arising as a mean-field limit of spatially inhomogeneous …
