Abstract
An optimization device includes: k first calculation circuits, N−k second calculation circuits, a selection circuit, an identification information calculation circuit and an update circuit. The first calculation circuit calculates a first energy change of an Ising model due to a change of a value of one of k first bits having values of 1 and a change of a value of a second bit having a value of 0 selected based on a generated first random number. The second calculation circuit calculates a second energy change of the Ising model due to a change of a value of one of (N−k) third bits having the values of 0 and a change of a value of a fourth bit having a value of 1 selected based on a generated second random number.
