Distributed Gradient Tracking Methods with Guarantees for Computing a Solution to Stochastic MPECs
Mohammadjavad Ebrahimi, Uday V. Shanbhag, Farzad Yousefian
We consider a class of hierarchical multi-agent optimization problems over networks where agents seek to compute an approximate solution to a single-stage stochastic mathematical p…
Zeroth-Order Federated Methods for Stochastic MPECs and Nondifferentiable Nonconvex Hierarchical Optimization
Yuyang Qiu, Uday V. Shanbhag, Farzad Yousefian
Motivated by the emergence of federated learning (FL), we design and analyze federated methods for addressing: (i) Nondifferentiable nonconvex optimization; (ii) Bilevel optimizati…
A Distributed Iterative Tikhonov Method for Networked Monotone Aggregative Hierarchical Stochastic Games
Jinlong Lei, Uday V. Shanbhag, Jie Chen
We consider a class of nonsmooth aggregative games over networks in stochastic regimes, where each player is characterized by a composite cost function , is a smooth…
A regularized variance-reduced modified extragradient method for stochastic hierarchical games
Shisheng Cui, Uday V. Shanbhag, Mathias Staudigl
We consider an N-player hierarchical game in which the i-th player's objective comprises of an expectation-valued term, parametrized by rival decisions, and a hierarchical term. Su…
