Optimal stopping — In mathematics, the theory of optimal stopping is concerned with the problem of choosing a time to take a particular action, in order to maximise an expected reward or minimise an expected cost. Optimal stopping problems can be found in areas of… … Wikipedia
Optional stopping theorem — In probability theory, the optional stopping theorem (or Doob s optional sampling theorem) says that, under certain conditions, the expected value of a martingale at a stopping time is equal to its initial value (and also expected value at any… … Wikipedia
Loop-erased random walk — In mathematics, loop erased random walk is a model for a random simple path with important applications in combinatorics and, in physics, quantum field theory. It is intimately connected to the uniform spanning tree, a model for a random tree.… … Wikipedia
Robbins' problem (of optimal stopping) — is a problem of optimal stopping, sometimes referred to as the fourth secretary problem or the problem of minimizing the expected rank with full information. Its statement is as follows. Let X 1, ... , X n be independent, identically distributed… … Wikipedia
Stopped process — In mathematics, a stopped process is a stochastic process that is forced to assume the same value after a prescribed (possibly random) time.DefinitionLet * (Omega, mathcal{F}, mathbb{P}) be a probability space; * (mathbb{X}, mathcal{A}) be a… … Wikipedia
