| Outline of Final Research Achievements |
(1) To understand the mechanism of the vein network formation, we presented a numerical model that incorporates reaction-diffusion dynamics for the organism's growth front and current reinforcement dynamics. We also proposed an algorithm to predict the main vein's position from the frontal tip's propagation.
(2) We proposed a parameter-tuning algorithm, based on a selection principle. The algorithm exhibits the emergence of synchronization between populations of oscillators through autonomous changes of the intrinsic parameters. The populations show flexible parameter changes after the existing synchronized state is broken suddenly; that is, the system chooses appropriate values of the intrinsic parameters.
