Researchers have developed a new GPU-native parallel optimizer called \chisao{} designed to efficiently find all modes of multimodal black-box functions. This optimizer leverages a convergence-anticonvergence oscillation cycle, allowing it to freeze confirmed modes while continuing exploration with momentum-based anti-convergence and smoothed gradients. \chisao{} demonstrates superior performance on the Simon Fraser University optimization benchmark suite, achieving 100% mode recovery across various dimensions and showing significant speedups compared to traditional CPU-based methods, even under substantial noise.
