Researchers have introduced a new principle for minimizing residuals in nonlinear parametrizations of partial differential equation (PDE) solutions. This Dirac-Frenkel-Onsager principle addresses ill-conditioning by interpreting parameter non-uniqueness as gauge freedom. By incorporating a history variable, akin to momentum, and applying it selectively, the method enhances temporal smoothness and robustness, particularly in challenging singular regimes. AI
