New router blends neural operators and classical methods for PDE solving

Researchers have developed a new method to improve the efficiency of solving partial differential equations (PDEs). This approach combines classical numerical solvers with machine learning techniques, addressing the limitations of each individual method. The proposed 'greedy PDE router' aims to select the most effective solver at each step, mimicking an ideal greedy strategy to reduce computational cost and improve accuracy, particularly for high-frequency components.
