Numerical solution of the nonlinear fourth order Derrida-Lebowitz-Speer-Spohn equation using a structure-preserving Lagrangian scheme. The method [Düring, Matthes and Milišić, 2010] exploits the underlying gradient flow structure and is based on a fully discrete variant of the minimising movement scheme https://dx.doi.org/10.3934/dcdsb.2010...
