This problem can be stated in the following form: Imagine an administrator who wants to hire the best secretary out of n rankable applicants for a position. The applicants are interviewed one by one in random order. A decision about each particular applicant is to be made immediately after the interview. Once rejected, an applicant cannot be recalled. During the interview, the administrator can rank the applicant among all applicants interviewed so far but is unaware of the quality of yet unseen applicants. The question is about the optimal strategy stopping rule to maximize the probability of selecting the best applicant. Optimal Stopping : In mathematics, the theory of optimal stopping or early stopping is concerned with the problem of choosing a time to take a particular action, in order to maximize an expected reward or minimize an expected cost. If the decision to hire an applicant was to be taken in the end of interviewing all the n candidates, a simple solution is to use maximum selection algorithm of tracking the running maximum and who achieved it and selecting the overall maximum at the end. The difficult part of this problem is that the decision must be made immediately after interviewing a candidate.
A mathematical theory says the perfect age to get married is 26 — here’s why
One way to look at dating and other life choices is to consider them as decision-time problems. Imagine, for example that have a number of candidates for a job, and all can be expected to say yes. You want a recipe that maximizes your chance to pick the best.
It’s based on the “Optimal Stopping problem.” also referred to as the “Sultan’s Dowry Problem,” “37 Percent Rule,” or “Secretary Problem.
Are you stumped by the dating game? Never fear — Plus is here! In this article we’ll look at one of the central questions of dating: how many people should you date before settling for something a little more serious? Why is that a good strategy? You don’t want to go for the very first person who comes along, even if they are great, because someone better might turn up later.
On the other hand, you don’t want to be too choosy: once you have rejected someone, you most likely won’t get them back. It’s a question of maximising probabilities. The value of depends on your habits — perhaps you meet lots of people through dating apps, or perhaps you only meet them through close friends and work.
That in itself is a tricky task, but perhaps you can come up with some system, or just use your gut feeling. Your strategy is to date of the people and then settle with the next person who is better.

The Secretary Problem
In this era of the Internet, meeting new people is much easier than before, but paradoxically, finding the proper partner is still a challenge. How do you know that the person sitting across from you at dinner is right for you? It can be tough to know for certain, but you can remarkably increase your chances of finding your ideal companion using Mathematicians developed a theory called the optimal stopping rule , the primary purpose of which is to find the most effective strategy of maximizing an expected payoff.
In this article we’ll look at one of the central questions of dating: how looks at results and problems related to the 37% rule in more detail.
Here, I was citing the secretary problem without understanding it at all. The problem is given n candidates, how do you maximize the probability of marrying the best one when you must date the candidates in sequence. Your only options are to pass or to marry. You do not know what the maximum score a candidate can have — in fact you have no idea what the distribution of the candidates is at all. The simplicity of the solution is largely dependent on the fact you know very little.
Assuming you use this strategy, what is the likelihood of choosing 1 to marry?
The new site update is up! In the real world , it is often applied to help decide when to stop dating and get married. The critique of this is that n, the quantity of possible people to date, is without defined variance if we assume it is distributed with a heavy tail. That is, for George Clooney, the n is enormous hundreds of thousands of people would be willing to marry George Clooney, probably , for the average person, it is smaller, and you don’t get to know if you’re George Clooney until you learn that you’re George Clooney.
I’m pretty sure I’m not George Clooney.
Marry the person you’re with or keep dating? With some details abstracted, these problems share a similar structure. The goal is to pick the best.
The secretary problem is a problem that demonstrates a scenario involving optimal stopping theory. It is also known as the marriage problem , the sultan’s dowry problem , the fussy suitor problem , the googol game , and the best choice problem. The applicants are interviewed one by one in random order. A decision about each particular applicant is to be made immediately after the interview.
Once rejected, an applicant cannot be recalled. During the interview, the administrator gains information sufficient to rank the applicant among all applicants interviewed so far, but is unaware of the quality of yet unseen applicants. The question is about the optimal strategy stopping rule to maximize the probability of selecting the best applicant. If the decision can be deferred to the end, this can be solved by the simple maximum selection algorithm of tracking the running maximum and who achieved it , and selecting the overall maximum at the end.
The difficulty is that the decision must be made immediately. The shortest rigorous proof known so far is provided by the odds algorithm Bruss A candidate is defined as an applicant who, when interviewed, is better than all the applicants interviewed previously. Skip is used to mean “reject immediately after the interview”. Since the objective in the problem is to select the single best applicant, only candidates will be considered for acceptance.
The “candidate” in this context corresponds to the concept of record in permutation.

Who solved the Secretary Problem? Statistical Science, 4 (3) (), pp. . Google Scholar. Mitha, Mitha.
If not, you can read an explanation here. The problem as presented is just an approximation of real life, designed to be easier to solve. Nonetheless, from time to time I have seen people attempt to use it as a guide for decision-making about things such as hiring, finding a job, or dating. All models must simplify in order to be useful and illustrate their point. But the secretary problem is such a poor approximation of real life that we should not see it as useful for guiding our actual decisions.
I came to this conclusion while preparing for a long interview with the author of Algorithms to Live By , Brian Christian. The optimum solution, when you have a large sample of applicants, is to just observe for the first Amusingly, your chance of choosing the best applicant will also be Should we spend the first That would suggest men start seriously looking for a life partner at 39 — and women at Added: Note that in this model you would want to include your entire life as the relevant search period — not just your youth — because being open to searching longer raises your chance of finding the best person in your whole dating pool, and the model features no cost to searching, or benefit of deciding sooner.
The reason the problem spits out such a questionable answer is obvious enough: every single part of this setup is a bad match for the world we live in. Here are some differences you would confront:. Each of these deviations from real life is a big deal that could materially affect the answer.
First-years: Don’t fall in love, according to math
And this is what I told them. The problem is mostly referred to as the Marriage Problem , sometimes also the Secretary Problem. We assume that there is a number of n guys that I could potentially date throughout my life.
The problem is given n candidates, how do you maximize the probability of marrying the best one when you must date the candidates in.
The following problem is best when not described by me:. Although there are many variations, the basic problem can be stated as follows:. There is a single secretarial position to fill. There are n applicants for the position, and the value of n is known. The applicants, if seen altogether, can be ranked from best to worst unambiguously. The applicants are interviewed sequentially in random order, with each order being equally likely.
Immediately after an interview, the interviewed applicant is either accepted or rejected, and the decision is irrevocable.

At that point in a selection process, you’ll have gathered enough information to make an informed decision, but you won’t have wasted too much time looking at more options than necessary. A common thought experiment to demonstrate this theory – developed by un-PC math guys in the s – is called “The Secretary Problem.
In the hypothetical, you can only screen secretaries once. If you reject a candidate, you can’t go back and hire them later since they might have accepted another job. The question is, how deep into the pool of applicants do you go to maximize your chance of finding the best one? If you interview just three applicants, the authors explain, your best bet is making a decision based on the strength of the second candidate.
Or you may take your chances on a dating app—but those become easily this problem has come in many forms: “the secretary problem,” “the.

Tight time frames, local competing projects, and a chronic labor shortage all make hiring one of the hardest parts of your project. Like dating, apartment hunting, and other forms of comparison shopping, you can optimize hiring by using the percent rule. The percent rule is all about spending just the right amount of time to make a decision that results in the best possible outcome.
The solution, 37 percent, is the optimal amount of effort to put into researching choices before taking decisive action on the next best option — which is mathematically proven to be the best option, minimizing regret and achieving the highest likelihood for satisfaction. For a hiring-type of decision, the best outcome is the one that maxes out your chances of getting the best candidate available.
The secretary problem helps an employer find the optimal candidate for a job out of a large pool of students’ dating lives can be found in . While there is.
Okay, go on. This led me on a rabbit hunt through the internet to understand where that number the 37 percent came from. This is also where the concept of e started to go a little over my head and I stopped Googling. I did enjoy this simplified example of the setup, though, which is also called the Secretary Problem , from Scientific American in Ask someone to take as many slips of paper as he pleases, and on each slip write a different positive number.
The numbers may range from small fractions of 1 to a number the size of a googol 1 followed by a hundred 0s or even larger. These slips are turned face down and shuffled over the top of a table. One at a time you turn the slips face up. The aim is to stop turning when you come to the number that you guess to be the largest of the series.
You cannot go back and pick a previously turned slip. If you turn over all the slips, then of course you must pick the last one turned. Back to dating. To demonstrate this Optimal Stopping Theory, the Science Vs team lays out an example: If a year-old would like to be married by age 35, she would therefore have 20 years of dating ahead of her.
