Query: Neural multigrid for gauge theories and other disordered systems   We present evidence that multigrid works for wave equations in disordered
systems, e.g. in the presence of gauge fields, no matter how strong the
disorder, but one needs to introduce a "neural computations" point of view into
large scale simulations: First, the system must learn how to do the simulations
efficiently, then do the simulation (fast).
  The method can also be used to provide smooth interpolation kernels which are
needed in multigrid Monte Carlo updates.
