WebProphet inequalities are a central object of study in optimal stopping theory. A gambler is sent values online, sampled from an instance of independent distributions, in an adversarial, random or selected order, depending on the model. When observing each value, the gambler either accepts it as a reward or irrevocably rejects it and proceeds to observe the next … WebThis is a very short introduction to main concepts of the theory of optimal stopping, value functions and dynamic programming principles. 1 Notes on optimal stopping: Three main …

WebOne approach is to consider optimal stopping as a type of decision making under uncertainty problem, e.g., Dixit and Pindyck (1994). In this context, optimal stopping can be formulated as a dynamic programming problem involving a binary choice, stop or continue, over all future decision dates. WebThe Agency’s Optimal Policy.

WebInterventions are then triggered by setting model thresholds. These are heuristic-driven, lacking guarantees regarding optimality. To model the evolution of system behavior, we introduce the concept of a hazard rate process. We show that the OTI problem is equivalent to an optimal stopping problem on the associated hazard rate process.
