Abstract
An information processing apparatus manufactured at low cost and with ease and that is capable of making a search for a ground state of an arbitrary Ising model. An information processing unit containing a plurality of semiconductor chips, each retains a value of one spin or values of a plurality of spins and simulates interactions among the spins, inter-chip wiring between the necessary semiconductor chips, and a control unit that cause each semiconductor chip to perform interaction computation. The control unit converts data of a problem into data of a lattice-shaped Ising model, which is possibly expressed by the plurality of semiconductor chips, without causing a spin arrangement, in a ground state of an Ising model for the problem, to be changed. The data of the lattice-shaped Ising model is divided for allocation to the plurality of semiconductor chips, and causes each semiconductor chip to perform the interaction computation.
