Greedy permanent magnet optimization

A number of scientific fields rely on placing permanent magnets in order to produce a desired magnetic field.We have shown in recent work that the placement process can be formulated as sparse regression.However, binary, grid-aligned solutions are desired for realistic engineering designs.We now show that the binary permanent magnet problem can be
