Researchers have developed a new method called PosEDO for online calibration of black-box social simulators. This approach enhances evolutionary dynamic optimization by incorporating an observation-conditioned signal derived from a posterior distribution over simulator parameters. PosEDO learns this signal during evolutionary evaluation, using shifts in the posterior for change detection and posterior samples for population adaptation, and updates the posterior without additional simulator calls. Experiments on economic and financial simulators demonstrate that PosEDO outperforms existing methods in calibration accuracy, optimization performance, and change-detection quality. AI
