PINNs solver applied to existing problem tests about neuralpde.jl HOT 4 CLOSED

Where did the mean field game issue go?

Indeed, now that it's starting to get documented, feel free to just post some test problems and see if it's working on them. We need to keep pushing the strategies in different ways. #46 is still the most puzzling thing!

The EmoryMLIP/MFGnet.jl#2 has been idle since March 2 but NeuralNetDiffEq is close to solving this one without looking over their shoulders.

I suggest addressing all the test models from here: https://arxiv.org/pdf/1811.08782.pdf. You have already dealt with the DGM method very efficiently in the UDE paper. Nevertheless, the set of test problems is good. NeuralNetDiffEq would need to add: Fokker-Planck (Kolmogorov forward), Systemic risk and Mean Field Games (FBSDE system of HJB+FP).

Still linking all these test problem is #52 which should be music to @KirillZubov in terms of similar steps to PINNs. You can save time by eliminating inefficient steps in their work like local solvers and expectation/weak solution. This stuff is already up and running on github/Python and can be a good benchmark for Julia/NeuralNetDiffEq (they are using massive GPU power though).

I'm not sure what's actionable here.
