Researchers have developed Co4ICF, a novel framework that integrates a physics-informed surrogate model with a Proximal Policy Optimization (PPO)-based pulse optimizer. This co-evolving approach addresses the issue of out-of-distribution predictions in offline-trained surrogate models for Inertial Confinement Fusion (ICF). By iteratively fine-tuning the surrogate on data generated by the optimizer, Co4ICF corrects extrapolation errors and improves prediction reliability. In simulations, Co4ICF achieved a 146.1% normalized yield in the MULTI environment and a 246.9% normalized yield when evaluated in a more complex 2D-MULTI setting, demonstrating the effectiveness of its co-evolving mechanism.
