Optimal Nonergodic Primal-Dual Complexity of Efficient Inexact Parameter-Free Augmented Lagrangian Methods

Arnesh Sujanani, Saeed Ghadimi, Henry Wołkowicz +1

Augmented Lagrangian (AL) methods are a classical framework for constrained optimization, but for directly verifiable approximate KKT points, known first-order complexity bounds fo…

Optimal Diagonal Preconditioning Beyond Worst-Case Conditioning: Theory and Practice of Omega Scaling

Saeed Ghadimi, Woosuk L. Jung, Arnesh Sujanani +2

We study optimal diagonal preconditioning using the classical worst-case I^º-condition number and the averaging-based I¨‰-condition number. For the I^º-optimal preconditioning p…

Optimal Zeroth-Order Bilevel Optimization

Alireza Aghasi, Jeongyeol Kwon, Saeed Ghadimi

In this paper, we develop zeroth-order algorithms with provably (nearly) optimal sample complexity for stochastic bilevel optimization, where only noisy function evaluations are av…
