Keywords:Coherent Ising Machine

A coherent Ising machine (CIM) has been studied as a physical computer solving optimization problems based on the Ising model, the operation of which is conventionally analysed by a theoretical model based on mean field approximation. On contrary, this paper applies a travelling-wave model, which is simpler and more suitable for the actual system, to CIM and shows that it properly simulates the CIM operation.
