Recent Preprints/Publications
-
[2024.11] Our draft Convergence Analysis and Acceleration of Fictitious Play for General Mean-Field Games via the Best Response is online. In this paper, we give the convergence rate of fictitious play for non-potential mean-field games by studying the stability of the best response mapping.
-
[2024.10] Our draft Zeroth-order Stochastic Cubic Newton Method with Low-rank Hessian Estimation is online.
-
[2024.08] Our paper A bilevel optimization method for inverse mean-field games is accepted by Inverse Problems.
