Results of solving a combinatorial optimization problem via annealing using the proposed probabilistic-bit (p-bit) circuit. A three-dimensional spin-glass problem with 8×8×8 = 512 spins was used as an example. By gradually varying the delay time within the p-bit circuit, the effective temperature of the probabilistic bits can be controlled. Gradually cooling the system leads to convergence to the ground state, i.e., successful computation of the optimal combination.
