Patent Searching and Data


Title:
COMBINATORIAL PROBLEM COMPUTING SYSTEM, ISING MACHINE, AUXILIARY-VARIABLE COMPUTING DEVICE, COMBINATORIAL PROBLEM COMPUTING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/170883
Kind Code:
A1
Abstract:
This combinatorial problem computing system includes: an auxiliary-variable computing device that computes and outputs an auxiliary variable for correcting an Ising Hamiltonian representing a combinatorial optimization problem, said auxiliary variable suppressing variations in the absolute values between variables so as not to affect the solution candidate search process of an Ising machine; and an Ising machine that corrects an Ising Hamiltonian on the basis of an auxiliary variable and executes a solution candidate search process on the basis of the corrected Ising Hamiltonian.
