论文摘要
接触跟踪可以将其视为两个过程之间的种族：感染过程和追踪过程。在本文中，我们研究了一个简单的感染模型，该模型传播在树上，并且一次稳定一个节点的示踪剂。我们关注这个问题，示踪剂应该如何选择节点来稳定以防止感染进一步传播？我们研究简单的策略，该策略根据时间，传染性或产生新接触的可能性优先考虑节点。
Contact tracing can be thought of as a race between two processes: an infection process and a tracing process. In this paper, we study a simple model of infection spreading on a tree, and a tracer who stabilizes one node at a time. We focus on the question, how should the tracer choose nodes to stabilize so as to prevent the infection from spreading further? We study simple policies, which prioritize nodes based on time, infectiousness, or probability of generating new contacts.
