Archaeology of random recursive dags and Cooper-Frieze random networks. (arXiv:2207.14601v1 [math.PR])

We study the problem of finding the root vertex in large growing networks. We
prove that it is possible to construct confidence sets of size independent of
the number of vertices in the network that contain the root vertex with high
probability in various models of random networks. The models include uniform
random recursive dags and uniform Cooper-Frieze random graphs.
