论文摘要
设计搜索时间优化的导航策略在科学的各种跨学科分支中仍然令人感兴趣。在这里,我们专注于微观自行搜索者,即在嘈杂和密闭的环境中活跃的布朗人步行者,这些搜索者是由这样的自主策略介导的,即重置。因此,重置可以停止运动,并迫使步行者根据不需要步行者控制的外部计时器间歇性地从初始配置重新启动。特别是,重置坐标是在整个地形上淬灭(固定)或退火(波动)。尽管该策略依赖于简单的规则,但与原始搜索相反,它显示出对搜索时间统计信息的重大影响。我们表明,重置驱动的协议可以稳健地基于固有的搜索时间波动来降低这些主动搜索者的性能。值得注意的是,对于退火状况,总是发现重置可以加快搜索过程。这些功能以及它们适用于从排队系统,计算机科学到生活系统开始的更一般优化问题,使基于重置的策略普遍有前途。
Designing navigation strategies for search time optimization remains of interest in various interdisciplinary branches in science. In here, we focus on microscopic self-propelled searchers namely active Brownian walkers in noisy and confined environment which are mediated by one such autonomous strategy namely resetting. As such, resetting stops the motion and compels the walkers to restart from the initial configuration intermittently according to an external timer that does not require control by the walkers. In particular, the resetting coordinates are either quenched (fixed) or annealed (fluctuating) over the entire topography. Although the strategy relies upon simple rules, it shows a significant ramification on the search time statistics in contrast to the original search. We show that the resetting driven protocols mitigate the performance of these active searchers based, robustly, on the inherent search time fluctuations. Notably, for the annealed condition, resetting is always found to expedite the search process. These features, as well as their applicability to more general optimization problems starting from queuing systems, computer science to living systems, make resetting based strategies universally promising.
