Researchers have developed a unified theoretical framework for black-box optimization (BBO) methods, including Evolution Strategies (ES), Consensus-Based Optimization (CBO), and Optimization via Integration (OVI). This framework reveals that the primary differences between these methods lie in their fitness aggregation and consensus scope choices. By leveraging these insights, the researchers introduced hybrid optimizers, such as ES-OVI and CBO-OVI, which interpolate between existing techniques. These hybrid approaches have demonstrated improved performance and robustness on various benchmarks, including continuous control tasks and language model merging. AI
