The Simple Strategy-Iteration Method is Strongly Polynomial for the Turn-Based Deterministic Forward Game

Sanyou Mei, Chunlin Sun, Yinyu Ye

We study Turn-Based Deterministic Forward Games (TBDFGs), the subclass of turn-based deterministic zero-sum games in which no directed cycle contains actions controlled by both pla…

A first-order method for nonconvex-strongly-concave constrained minimax optimization

Zhaosong Lu, Sanyou Mei

In this paper we study a nonconvex-strongly-concave constrained minimax problem. Specifically, we propose a first-order augmented Lagrangian method for solving it, whose subproblem…

Solving bilevel optimization via sequential minimax optimization

Zhaosong Lu, Sanyou Mei

In this paper we propose a sequential minimax optimization (SMO) method for solving a class of constrained bilevel optimization problems in which the lower-level part is a possibly…

Variance-reduced first-order methods for deterministically constrained stochastic nonconvex optimization with strong convergence guarantees

Zhaosong Lu, Sanyou Mei, Yifeng Xiao

In this paper, we study a class of deterministically constrained stochastic optimization problems. Existing methods typically aim to find an -stochastic stationary point, where…

A first-order augmented Lagrangian method for constrained minimax optimization

Zhaosong Lu, Sanyou Mei

In this paper we study a class of constrained minimax problems. In particular, we propose a first-order augmented Lagrangian method for solving them, whose subproblems turn out to…

Primal-dual extrapolation methods for monotone inclusions under local Lipschitz continuity

Zhaosong Lu, Sanyou Mei

In this paper we consider a class of monotone inclusion (MI) problems of finding a zero of the sum of two monotone operators, in which one operator is maximal monotone while the ot…
