| Abstract(in English) | A Hopfield network is a good tool for solving combinatorial optimization problems, even though it sometimes fails to find out an optimal solution. According to the preceding study, a virtual magnetic diminuendo method proposed recently improves the score through controlling a threshold of the network as a magnetic parameter. Then, in order to make clear its mechanism, behavior of the Hopfield network is analyzed carefully in this article. As a result, it is found that i) a critical magnetic parameter separates firing and quiescent regions, ii) crossing this critical point makes the model control the easiness of neurons' activity, and iii) it leads the model easier to reach the goal. |
