Fast swap regret minimization and applications to approximate correlated equilibria

B Peng, A Rubinstein - Proceedings of the 56th Annual ACM Symposium …, 2024 - dl.acm.org
We give a simple and computationally efficient algorithm that, for any constant ε> 0, obtains ε
T-swap regret within only T=(n) rounds; this is an exponential improvement compared to the …

Computing optimal equilibria and mechanisms via learning in zero-sum extensive-form games

B Zhang, G Farina, I Anagnostides… - Advances in …, 2024 - proceedings.neurips.cc
We introduce a new approach for computing optimal equilibria via learning in games. It
applies to extensive-form settings with any number of players, including mechanism design …

Exploiting hidden structures in non-convex games for convergence to Nash equilibrium

I Sakos, EV Vlatakis-Gkaragkounis… - Advances in …, 2024 - proceedings.neurips.cc
A wide array of modern machine learning applications–from adversarial models to multi-

On the Convergence of Learning Algorithms in Bayesian Auction Games

M Bichler, SB Lunowa, M Oberlechner… - arXiv preprint arXiv …, 2023 - arxiv.org
Equilibrium problems in Bayesian auction games can be described as systems of differential
equations. Depending on the model assumptions, these equations might be such that we do …

Paying to Do Better: Games with Payments between Learning Agents

Y Kolumbus, J Halpern, É Tardos - arXiv preprint arXiv:2405.20880, 2024 - arxiv.org
In repeated games, such as auctions, players typically use learning algorithms to choose
their actions. The use of such autonomous learning agents has become widespread on …

Higher-Order Uncoupled Dynamics Do Not Lead to Nash Equilibrium-Except When They Do

S Toonsi, J Shamma - Advances in Neural Information …, 2024 - proceedings.neurips.cc
The framework of multi-agent learning explores the dynamics of how an agent's strategies
evolve in response to the evolving strategies of other agents. Of particular interest is whether …

Counter-intuitive effects of Q-learning exploration in a congestion dilemma

C Carissimo - IEEE Access, 2024 - ieeexplore.ieee.org
Exploration is an integral part of learning dynamics which allows algorithms to search a
space of solutions. When many algorithms simultaneously explore, this can lead to counter …

[HTML][HTML] Nash Equilibria and Undecidability in Generic Physical Interactions—A Free Energy Perspective

C Fields, JF Glazebrook - Games, 2024 - mdpi.com
We start from the fundamental premise that any physical interaction can be interpreted as a
game. To demonstrate this, we draw upon the free energy principle and the theory of …

Learning in Stochastic Stackelberg Games

We present a learning algorithm for players to converge to their stationary policies in a
general sum stochastic sequential Stackelberg game. The algorithm is a two time scale …

Swim till You Sink: Computing the Limit of a Game

R Hakim, J Milionis, C Papadimitriou… - … Symposium on Algorithmic …, 2024 - Springer
During 2023, two interesting results were proven about the limit behavior of game dynamics:
First, it was shown that there is a game for which no dynamics converges to the Nash …
