Rather, given a user-supplied list of symmetries, minimize deviation from them. Simplest example: isotropic 2-d wave equation on square grids. Rotational symmetry may or may not be important in an application but (except for stupidly short time steps) is not a feature of the discrete solutions. If a user specifies it, perturb the difference equations to minimize violation of that symmetry. | |
