Sure. Actually we've designed the two high-dimensional problems to have analytical solutions. Please refer to these two sections of code:

I was wondering:
1: did you use the lbfgs alone, or adam_lbfgs for optimization? In your paper I found only states lbfgs. A bit confused.
2: is below the hyperparameters for all the equations?
"[adam_param={'lr': 1e-3, 'betas': (0.9, 0.999)}, lbfgs_param={'lr': 1, 'max_iter': 20]"
or you've also optimized the hypers?
