Mean-Field Selective Optimal Control via Transient Leadership

A mean-rield selective optimal control problem of multipopulation dynamics via transient leadership is considered. The agents in the system are described by their spatial position and their probability of belonging to a certain population. The dynamics in the control problem is characterized by the presence of an activation function which tunes the control on each agent according to the membership to a population, which, in turn, evolves according to a Markov-type jump process. In this way, a hypothetical policy maker can select a restricted pool of agents to act upon based, for instance, on their time-dependent influence on the rest of the population. A finite-particle control problem is studied and its mean-field limit is identified via Gamma-convergence, ensuring convergence of optimal controls. The dynamics of the mean-field optimal control is governed by a continuity-type equation without diffusion. Specific applications in the context of opinion dynamics are discussed with some numerical experiments.

Automated summary

This paper studies a mean-field selective optimal control problem of multipopulation dynamics via transient leadership. The problem considers the spatial position and probability of belonging to a certain population for the agents, and introduces an activation function to tune the control on each agent. By using Gamma-convergence, the mean-field limit of the finite-particle control problem is identified, ensuring the convergence of optimal controls. Specific applications in the context of opinion dynamics are discussed.
