From the article it looks like half AI guessing the solution, half some static algorithm fixing the result to be better. Not sure how it's supposed to really work.
one variant of this is sciml approaches where you use an ODE solver wrapped around a NN. the ODE solver guarantees you get the right conversation laws which NNs don't do well and the NN is more accurate than the hand written model since it doesn't ignore the higher order effects.
