Abstract

Analog computation is a processing method that solves a given problem by utilizing an analogy of a physical system to the problem. An idea is presented here for relating the behavior of quantum-flux parametron circuits to analog computation. As an example, a method is proposed for solving a combinatorial optimization problem, the max-cut problem, by utilizing the properties of quantum-flux parametron circuits. In problem solving, a parametron circuit is constructed whose free energy is related to the objective functionof a given problem and then is made to settle down to its minimum energy state. The solution to the problem can be obtained by checking the final state that the circuit reaches. The effectiveness of this method was confirmedby computer simulation for sample problem instances.
