Feedback-controlled electromigration (FCE) has been employed to control metal nanowires with quantized conductance and to create nanogaps. The setting of the experimental parameters based on experiences is a common practice in FCE. However, tuning the optimization of parameters is intractable because trying all different combinations systematically is practically impossible. Therefore, we proposed...
Recently, the ability to analyze big data has been required for the optimization of social systems and the development of artificial intelligence. Consequently, the solution of combinatorial optimization problems has become important in recent years, especially for the suitable operation of infrastructures. However, combinatorial optimization problems have unique properties that the number of candidate...
Recently, the new computing architecture using Ising spin model has been attracting considerable attention. It is well known that the Ising spin model represents the physical properties of ferromagnetic materials in terms of statistical mechanics. In this model, the spin states are varied in order to minimize the system energy automatically, by the interaction between connected adjacent spins. The...
