多头绒泡菌的疟原虫是一种单细胞巨型变形虫，在适当的条件下可以生长到宏观规模，并且以其计算能力而闻名。在这项研究中，我们试图观察疟原虫在开放环境中的长期探索行为，并评估其效率。为此，我们开发了一个具有可扩展基板的实验系统。实验结果表明，等离子体运动速度的频率分布符合幂函数拟合。通过模拟，我们进一步尝试估计了利用疟原虫模式实施的探索效率，并证实了它实际上是有效的。
The plasmodium ofPhysarum polycephalumis a unicellular giant amoeba that grows up to macroscopic scale under appropriate condition, and is known to its computational abilities. In this study, we tried to observe the long-term exploratory behavior of the plasmodium in an open environment and to evaluate its efficiency. For this purpose, we developed an experimental system with an extendable substrate. As a result of the experiment, we found that the frequency distribution of the speed of plasmodial locomotion is fitted by power function. By simulation, we further tried to estimate the efficiency of the exploration implemented with the patterns from the plasmodium, and confirmed that it is actually effective.
