Abstract
An optimization problem that may be cast in the context of domain wall s in ferromagnets and spin glasses, lattice animals, and percolation i s described. Numerical calculations in two and three dimensions show t hat a new universality class is obtained. In the strong disorder limit interfaces are not self-affine but fractal. Further, the nontrivial g round state of frustrated spin glasses is straightforwardly obtained i n this limit.
