Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Studentxpublishesapaperinwhichtheycitestudenty’swork(youcan assume all of the students have been around long enough to have prior research that can be cited).
