Abstract
This paper considered an optimality of branching network of tree root by using generation method of branch system that was obtained by previous research. Especially, we focused attention on a dynamics that is one of important growth factor of branch system and showed the construction method. And one example of the model of branching network of tree root that was obtained by using of the method of this research was shown, and it was compared with the model obtained with generation method of branch system. Consequently, generation method of branching network of tree root with dynamic stimulation from the outside as a growth factor could be constructed.
