Bacteria which grow not on the featureless agar plates of the microbiology lab but in the real world must navigate topologies which are non-trivially complex, such as mazes or fractals. We show that chemo-sensitive motile {} can efficiently explore non-trivial mazes in times much shorter than a no-memory (Markovian) walk would predict, and can collectively escape from a fractal topology. The strategies used by the bacteria include individual power-law probability distribution function exploration, the launching of chemotactic collective waves with preferential branching at maze nodes and defeating of fractal pumping, and bet hedging in case the more risky attempts to find food fail.

迷宫和分形中的细菌寻径和集体逃逸

并非在微生物实验室的琼脂平板上生长的细菌，而是在现实世界中生长的细菌，必须在非平凡的拓扑结构中导航，例如迷宫或分形。我们表明，对化学敏感的运动{}可以在比无记忆（马尔可夫式）行走更短的时间内有效地探索非平凡的迷宫，并且可以集体逃离分形拓扑。细菌使用的策略包括探索个体幂律概率分布函数，在迷宫节​​点处发射具有优先分支的趋化性集体波和分形抽水失败，以及在风险更大的寻找食物的尝试失败时进行对冲。
