$N$ independent and identically distributed random variables are sampled sequentially from a known continuous distribution. The optimal policy for maximizing the probability of obtaining the maximum of the sequence is formulated generally for any information source and illustrated with several examples. When following the optimal policy, it is shown in each case considered that the expected number of random variables sampled is simply related to the probability of selecting the maximum of the sequence. This relationship is posed as a conjecture for all information sources.
