The Sobolev gradient concept has been developed in the 1970s, with a first publication in 1985, and an introduction can be found at: Ranka

I would like to learn how strong the impact of Sobolev gradients has been in numerical partial differential equations.

Is it one of several possible tools for nonlinear pde, or a powerful approach without "competitors"?
