At each time t, a decision maker observes the state X t of the Markov chain and decides whether to continue or stop the process. If the decision maker decides to continue, he incurs a continuation cost c t ( X t) and the state evolves. primus astronaut hoodieWebFinite Horizon Problems 2.3 means that if it is optimal to stop with a candidate at j, then it is optimal to stop with a candidate at j +1,since (j +1)/n > j/n ≥ W j ≥ W j+1.
