Co4ICF: Co-evolving Physics-informed Surrogate and RL-based Pulse Optimizer for Inertial Confinement Fusion

Published in The 32nd ACM SIGKDD Conference on Knowledge Discovery and Data Mining (SIGKDD 2026), 2026

We present Co4ICF, a closed-loop AI4Physics system coupling a physics-informed surrogate with an RL-based optimizer for inertial confinement fusion pulse design.
