摘要

在这项研究中,我们探讨了随机重置对t分形网络上随机行走动力学的影响。利用生成函数技术,建立了首次通过时间(FPT)生成函数之间的递推关系,导出了重置后的平均首次通过时间(MFPT)与未重置后的平均首次通过时间(MFPT)生成函数之间的关系。我们的分析涵盖了随机步行者从起始位置到达目标地点的各种场景;对于每种情况,我们确定了使MFPT最小化的最佳重置概率γ*。我们将结果与不重置的MFPT进行了比较,发现包含重置显著提高了搜索效率,特别是随着网络规模的增加。我们的研究结果强调了随机重置作为复杂网络中搜索过程优化的有效策略的潜力,为高效搜索策略至关重要的各个领域的应用提供了有价值的见解。

Random Walk on T-Fractal with Stochastic Resetting.

In this study, we explore the impact of stochastic resetting on the dynamics of random walks on a T-fractal network. By employing the generating function technique, we establish a recursive relation between the generating function of the first passage time (FPT) and derive the relationship between the mean first passage time (MFPT) with resetting and the generating function of the FPT without resetting. Our analysis covers various scenarios for a random walker reaching a target site from the starting position; for each case, we determine the optimal resetting probability γ* that minimizes the MFPT. We compare the results with the MFPT without resetting and find that the inclusion of resetting significantly enhances the search efficiency, particularly as the size of the network increases. Our findings highlight the potential of stochastic resetting as an effective strategy for the optimization of search processes in complex networks, offering valuable insights for applications in various fields in which efficient search strategies are crucial.

期刊介绍: Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
