Researchers have developed JANUS, a novel plug-and-play module designed to enhance population-based optimizers like CMA-ES. JANUS extracts local geometric signals from recent evaluation traces without replacing the host optimizer, estimating a local Jacobian for both exploitation and exploration candidates. This method improves performance on a significant majority of BBOB functions across various dimensions and achieves top results on structured and multi-objective tasks, including UAV path planning, with no offline training cost.
