Parallel Model-Based Derivative-Free Optimization via Rank-Two KKT Updates

Donghan Wu, Pengcheng Xie

Derivative-free optimization (DFO) addresses unconstrained problems $\min_{\x\in\RR^n} f(\x)$ where f is accessed only through a zeroth-order oracle. Model-based trust-region met…

Low-Rank KKT Updates and a Parallel Flipping Mechanism for Model-Based Derivative-Free Optimization

Donghan Wu, Pengcheng Xie

Model-based derivative-free optimization relies on quadratic interpolation, but maintaining these models typically requires O(m3) linear system solves. We show that fo…
