A magnetic system for solving one or more quadratic optimization problems by associating each of a plurality of variables of a quadratic optimization problem with a nanomagnet subset of a nanomagnet array, driving the nanomagnets of the nanomagnet subset to an excited state, allowing the nanomagnets of the nanomagnet subset to enter a relaxed state after being driven to an excited state, wherein the nanomagnets magnetically couple with one another in the relaxed state to minimize the total magnetic coupling energy of the nanomagnet array, and sensing a magnetic coupling of the nanomagnets of the nanomagnet subset to solve the quadratic optimization problem.

A system and method for image-processing that will facilitate automatically analyzing and estimating atomic force microscopy (AFM) images and magnetic force microscopy (MFM) images of fabricated nanomagnetic arrays to identify the magnetization states of the nanomagnets in the array. The system and method will automatically estimate the magnetization states of nanomagnetics disks into one of a plurality of energy minimum magnetization state configurations and provide an annotated image of the results of the estimation.
