Title: 通道形成通过趋化活性布朗粒子增强目标消耗

Abstract: In many situations, simply finding a target during a search is not enough. It is equally important to be able to return to that target repeatedly or to enable a larger community to locate and utilize it. While first passage time is commonly used to measure search success, relatively little is known about increasing the average rate of target encounters over time. Here, using an active Brownian particle model with chemotaxis, we demonstrate that when a searcher has no memory and there is no communication among multiple searchers, encoding information about the target's location in the environment outperforms purely memoryless strategies by boosting the overall hit rate. We further show that this approach reduces the impact of target size on a successful search and increases the total utilization time of the target. Show Chinese abstract

Abstract: 在许多情况下，仅仅在搜索中找到目标是不够的。能够反复返回到该目标，或使更大的社区定位和利用它同样重要。虽然首次通过时间通常用于衡量搜索的成功，但关于如何随时间提高目标相遇的平均速率了解较少。在这里，我们使用具有趋化性的主动布朗粒子模型，证明当搜索者没有记忆且多个搜索者之间没有通信时，将有关目标位置的信息编码到环境中比纯粹无记忆策略更有效，从而提高了总体命中率。我们进一步表明，这种方法降低了目标大小对成功搜索的影响，并增加了目标的总利用时间。
