\chisao{}: A GPU-Native Parallel Optimizer for Multimodal Black-Box Functions via Convergence-Anticonvergence Oscillation
arXiv:2606.26164v1 Announce Type: new Abstract: Finding all modes of a multimodal black-box function is a fundamental challenge in optimization, Bayesian inference, and scientific computing. Existing approaches -- basin-hopping, CMA-ES, multistart gradient descent -- operate sequentially and cannot exploit the massive parallelism of modern GPU hardware. We introduce \chisao{} (\textbf{C}onvergence-\textbf{H}alt-\textbf{I}nvert-\textbf{S}tick-\textbf{A}nd-\textbf{O}scillate), a GPU-native population optimizer that runs an entire sample batch simultaneously and exploits a deliberate convergence-
The continuous drive for more efficient AI and scientific computing, coupled with the increasing availability and power of GPU hardware, is pushing innovation in parallel optimization techniques.
This development addresses a fundamental limitation in complex optimization problems, offering significant speedups and enabling new capabilities in AI training, scientific modeling, and Bayesian inference.
The ability to run multimodal black-box optimizations at scale on GPUs will accelerate research and development in fields heavily reliant on such problems, potentially democratizing access to powerful optimization methods.
