Data-Efficient Time-Dependent PDE Surrogates: Graph Neural Simulators vs. Neural Operators

Graph Neural Simulators (GNS) is proposed as a principled surrogate modeling paradigm for time-dependent PDEs that mimics traditional numerical solvers, enabling stable long-horizon rollouts and strong inductive biases that enhance generalization.
