Method of Halved Interaction Elements with Regularity Arrangement that achieves Independent Double Systems for Scalable Fully Coupled Annealing Processing

In recent years, annealing processors have been developed as solutions to large-scale combinatorial optimization problems. In this paper, we propose a new method that has a high affinity with a scalable fully coupled annealing processor and halves the interaction in which there are squares of spins with sequence regularity. In addition, we applied the proposed interaction reduction plan this time to the 384-spin fully-coupled Ising machine using 16 chips conducted in the previous research [1], and succeeded in implementing two independent 384-spin fully-coupled Ising machines with 16 chips. The usefulness of the reduction plan is shown.
