Abstract (in Japanese) (See Japanese page) 
(in English) Population protocols are a theoretical model for modeling a set of units with low computational capabilities - so called agents - that can communicate with each other pairwise. Their possible applications are, for example, nano-robots consisting of only a few molecules or mobile sensors in a sensor network. Despite the performance limitations of a single agent, the entire population can fulfill global tasks that go beyond this limitation. For this purpose, it is often helpful to divide the agents into separate groups. In this way, for example, task distribution can be achieved. Exactly this subdivision, the exact k-partition problem, was dealt with in the doctoral dissertation [Yas22]. In addition to lower bounds on space complexity, upper bounds in the form of concrete protocols are also given. However, since the focus of the work is space complexity, the time complexity was only estimated using simulations. Therefore, in this work we focus on the time complexity aspect of those protocols and problems.
