AL Loop for Weights #59

Open tpr0p opened 1 year ago

Add the Augmented Lagrangian method for increasing weights in experimental optimization.

ichristen commented 1 year ago

I agree that it would be interesting to try this. I don’t know of any work that looks into this. People use very simple weighting functions. In the 3d_spots branch, we have a tanh test function that I think will be more stable. I suspect that people don’t use AL because balancing the weights is a very nonlinear function and it’s better to just go very slowly and use something that always works instead of tuning AL. But would be cool to try!
