Optimal substructure is a core property not just of dynamic programming problems but also of recursion in general. The optimal stopping rule prescribes always rejecting the first n/e applicants that are interviewed (where e is the base of the natural logarithm and has the value 2.71828) and then stopping at the first applicant who is better than every applicant interviewed so far (or continuing to the last applicant if this never occurs). Basically Dynamic programming can be applied on the optimization problems. Touzi N. (2013) Optimal Stopping and Dynamic Programming. An optimal stopping problem 4. Was there an anomaly during SN8's ascent which later led to the crash? As such, the explicit premise of the optimal stopping problem is the implicit premise of what it is to be alive. These techniques give an alternative formulation to the traditional dynamic programming framework used in stochastic control problems and have been demonstrated in examples including control of the running maximum of a diffusion, optimal stopping problems, and regime-switching diffusions.
