Estimation Network Design framework for efficient distributed optimization

no code implementations23 Apr 2024 Mattia Bianchi, Sergio Grammatico

Distributed decision problems features a group of agents that can only communicate over a peer-to-peer network, without a central memory.

An Efficient Risk-aware Branch MPC for Automated Driving that is Robust to Uncertain Vehicle Behaviors

no code implementations27 Mar 2024 Luyao Zhang, George Pantazis, Shaohang Han, Sergio Grammatico

One of the critical challenges in automated driving is ensuring safety of automated vehicles despite the unknown behavior of the other vehicles.

Automated Lane Merging via Game Theory and Branch Model Predictive Control

no code implementations25 Nov 2023 Luyao Zhang, Shaohang Han, Sergio Grammatico

To overcome the challenge of multi-modal driving behavior exhibited by the surrounding vehicles, we formulate the trajectory selection as a matrix game and compute some equilibrium solutions.

A Semi-Decentralized Tikhonov-based Algorithm for Optimal Generalized Nash Equilibrium Selection

no code implementations25 Apr 2023 Emilio Benenati, Wicak Ananduta, Sergio Grammatico

To optimally select a generalized Nash equilibrium, in this paper, we propose a semi-decentralized algorithm based on a double-layer Tikhonov regularization method.

Probabilistic Game-Theoretic Traffic Routing

1 code implementation6 Mar 2023 Emilio Benenati, Sergio Grammatico

We examine the routing problem for self-interested vehicles using stochastic decision strategies.

Online coalitional games for real-time payoff distribution with applications to energy markets

no code implementations28 Jan 2023 Aitazaz Ali Raja, Sergio Grammatico

Motivated by the markets operating on fast time scales, we present a framework for online coalitional games with time-varying coalitional values and propose real-time payoff distribution mechanisms.

A Market for Trading Forecasts: A Wagering Mechanism

no code implementations5 May 2022 Aitazaz Ali Raja, Pierre Pinson, Jalal Kazempour, Sergio Grammatico

This market delivers an aggregated forecast to the buyer (pre-event) and allocates a payoff to the sellers (post-event) for their contribution.

Optimal selection and tracking of generalized Nash equilibria in monotone games

no code implementations15 Mar 2022 Emilio Benenati, Wicak Ananduta, Sergio Grammatico

A fundamental open problem in monotone game theory is the computation of a specific generalized Nash equilibrium (GNE) among all the available ones, e. g. the optimal equilibrium with respect to a system-level objective.

Learning generalized Nash equilibria in monotone games: A hybrid adaptive extremum seeking control approach

no code implementations30 Sep 2021 Suad Krilašević, Sergio Grammatico

In this paper, we solve the problem of learning a generalized Nash equilibrium (GNE) in merely monotone games.

An extremum seeking algorithm for monotone Nash equilibrium problems

no code implementations16 Sep 2021 Suad Krilašević, Sergio Grammatico

In this paper we consider the problem of finding a Nash equilibrium (NE) via zeroth-order feedback information in games with merely monotone pseudogradient mapping.

Operationally-Safe Peer-to-Peer Energy Trading in Distribution Grids: A Game-Theoretic Market-Clearing Mechanism

no code implementations28 Jul 2021 Giuseppe Belgioioso, Wicak Ananduta, Sergio Grammatico, Carlos Ocampo-Martinez

In future distribution grids, prosumers (i. e., energy consumers with storage and/or production capabilities) will trade energy with each other and with the main grid.

Highway Traffic Control via Smart e-Mobility -- Part II: Dutch A13 Case Study

no code implementations18 Feb 2021 Carlo Cenedese, Michele Cucuzzella, Jacquelien M. A. Scherpen, Sergio Grammatico, Ming Cao

In this paper, we study how to alleviate highway traffic congestions by encouraging plug-in electric and hybrid vehicles to stop at charging stations around peak congestion times.

Highway Traffic Control via Smart e-Mobility -- Part I: Theory

no code implementations18 Feb 2021 Carlo Cenedese, Michele Cucuzzella, Jacquelien M. A. Scherpen, Sergio Grammatico, Ming Cao

In this paper, we study how to alleviate highway traffic congestion by encouraging plug-in hybrid and electric vehicles to stop at a charging station around peak congestion times.

Training Generative Adversarial Networks via stochastic Nash games

no code implementations17 Oct 2020 Barbara Franci, Sergio Grammatico

We also show convergence of an averaged variant of the SRFB algorithm to a neighborhood of the solution when only few samples are available.

Image Generation

A game-theoretic approach for Generative Adversarial Networks

no code implementations30 Mar 2020 Barbara Franci, Sergio Grammatico

Since the training can be cast as a stochastic Nash equilibrium problem, we rewrite it as a variational inequality and introduce an algorithm to compute an approximate solution.
