LieSolver uses Lie symmetries to solve IBVPs, outperforming PINNs

Researchers have developed LieSolver, a novel method for solving initial-boundary value problems (IBVPs) by integrating Lie symmetries to precisely enforce partial differential equations (PDEs). This approach embeds physical laws by learning solely from initial and boundary data, allowing for direct domain-wide error quantification. LieSolver has been implemented and tested on linear homogeneous PDEs, demonstrating superior speed and accuracy compared to physics-informed neural networks (PINNs) while producing more compact models.
