Researchers have identified a critical flaw in Physics-Informed Neural Networks (PINNs) where they can converge to incorrect solutions despite low residual losses. The study proposes a new adaptive pseudo-time stepping strategy that, combined with collocation-point resampling, helps PINNs avoid these spurious solutions. This method selects step sizes based on local stability criteria, improving accuracy and robustness across various partial differential equation benchmarks without requiring per-problem tuning. AI
