Researchers have developed a novel neural network architecture, termed AInstein, designed to solve the Riemannian Einstein equations. This Physics Informed Neural Network (PINN) approach has been extended to Lorentzian signature and successfully validated by reconstructing the Schwarzschild geometry. The architecture is further applied as a search method for arbitrary black hole solutions, incorporating topological constraints and utilizing the Petrov speciality index to identify algebraically general Petrov type I solutions, potentially leading to the discovery of new Lorentzian Einstein metrics with trapped interiors.
