Surprisingly, the problem has a fairly simple solution. And that’s the same with dating since you won’t ever know when you would find the ideal partner.”. Find out what the maths says in this fun article about the optimal stopping theory. If you randomly pick one person, then the probability that they are the one is 1/3 ≈ 33%. The main part of the lecture focuses on the powerful tool of backward induction, once used in the early 1900s by the mathematician Zermelo to prove the existence of an optimal strategy in chess. In another type of method, which we will discuss somewhat briefly, we use simulation in conjunction with a gradient or other method to approximate directly an optimal policy with a policy of a given parametric form. ... image caption The Optimal Stopping Theory suggests a formula for using apps like Tinder.
