Abstract (in Japanese) (See Japanese page) 
(in English) Our research group has proposed a VNT control method that is adaptive to traffic changes. The method is based on a dynamical system, called attractor selection, that models behavior where living organisms adapt to unknown changes in their surrounding environments and recover their conditions. One of important things of our VNT control method is how to determine attractors, i.e., VNT candidates. However, since the number of VNT candidates is limited, it is important to give diversity of attractors so that various kinds of VNTs are searched by attractor selection. Therefore, it is essential that we investigate measures of the diversity of attractors. In this paper, we introduce the hamming distance between VNT candidates as a measure of the diversity of attractors, and evaluate the behavior of VNT control based on attractor selection using the hamming distance. Evaluation results show that the hamming distance between VNT candidates represents the diversity of attractors because VNT candidates are widely distributed in state space when the hamming distance between VNT candidates is high.
