Abstract

We introduce extraction-type majority voting logic (E-MVL) that explores the ground state of an Ising spin model. The spin dynamics of E-MVL approximately follow that of thermal spins based on the Boltzmann distribution, even though E-MVL intentionally reduces the information of the problem graph by controlling the sparsity of problem graphs to realize high-speed calculation. We solved the Sherrington-Kirkpatrick spin-glass model using E-MVL and simulated annealing (SA). The probability of obtaining a solution with a 99% E-MVL accuracy is maintained at approximately 85% over the problem size, and E-MVL achieves a high accuracy compared to that of SA.
