loss gPINN

thank you first for code sharing. Could you explain to me why the loss function is composed of two values. Normally it is the sum of several weighted loss functions L = Lf + w Lg

Hi @Caruana0,

I'm not sure which example this screenshot is from. Assuming this is a gPINN 1D example using hard constraints, you are correct that the total loss is "the sum of several weighted loss functions L = Lf + w Lg." The two terms in the column are just "Lf" and "w Lg" shown separately.
