“…We define the state Sn as where Xu is the number written on the nth card, n:~, 2, ..• ,N. We then have P(Sn+1 =jISn=i)=O for j< i, = P(X n+1 = j) for j >I, A solution to the finite optimal stopping problem for large N was given by Ash and Jones (1964): sample until Zo = N -ka cards have been observed, and then stop after exposing the first card which is the largest of those seen so far (hereafter referred to as a candidate). Declare the candidate to be the largest in the deck.…”
