In the online random-arrival model, an algorithm receives a sequence of n requests that arrive in a random order. The algorithm is expected to make an irrevocable decision with regard to each request based only on the observed history. We consider the following natural extension of this model: each request arrives k times, and the arrival order is a random permutation of the kn arrivals; the al...

In 1963, Dynkin introduced the secretary problem [6]. In this problem, an algorithm is presented with n positive values, one by one. After each value, the algorithm must either accept or reject the value, where all decisions are final. The algorithm can only pick one value, and the goal is to pick the maximum value in the sequence. The name for this problem arises from a situation where n candi...
