I’ve been thinking about an “inverse secretary problem” for choosing contract jobs: 1. I have a limited time in which to secure the next contract 2. Each client has a different, unknown, maximum daily rate MDR they are willing pay. Given my goal is to find the client who will pay the highest daily rate before the deadline, what is the best strategy? My best guess at the moment is to start at a high rate, and gradually decrease it as the deadline approaches. But how can I use the information I gather about rejected client’s MDRs to decide the best daily rate to quote future potential clients? Is that actually your goal though? Are you sure you wouldn’t prefer a client who will offer repeat business at a decent but not maximal daily rate? How about a client who will offer a more interesting job, or one who will offer you the opportunity to learn something new?
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. I know that this is a difficult assumption to make. The only problem here: Once I settle for someone, I have settled. We also assume that I cannot go back to someone I have previously rejected.
Later, it was dubbed The Secretary Problem. others), the best way to proceed is to interview (or date) the first percent of the candidates.
Blog , North America , Sailing. If the dating secretary be problem to the end, this can be solved by secretary simple maximum secretary 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 math 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 math 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. The optimal policy for the problem is a stopping rule. It can be shown that the optimal strategy lies problem this class of strategies.
For small values dating n , the optimal r can also be obtained by standard dynamic programming methods. The optimal thresholds r and probability of selecting the best alternative P for several values of n are solving in the following table. Dating problem and several modifications can be solved including the proof of optimality in a straightforward the by the Odds algorithm , finding also has other applications.
Modifications for the secretary problem that can be solved by this algorithm include secretary availabilities of applicants, more general hypotheses for applicants to problem of interest to the decision maker, group interviews for applicants, as well as certain models for a random number of applicants.
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.
You have probably heard of the ‘secretary problem’, also called the for decision-making about things such as hiring, finding a job, or dating.
As they say, there are plenty of fish in the sea. And as mathematicians will tell you, the more fish you kiss, the better your chances of finding a catch. Sea life analogies aside, Dominik Czernia, a physics Ph. Although the underlying principle isn’t quite as romantic—the ” Optimal Stopping Problem ,” as it’s called, basically asks you to reject your first two of every five dates—Czernia has managed to make the art of love as close to a science as possible, with some spaghetti dinners required.
You don’t know the value of the offers before they come. With each offer, you must decide whether you accept or reject it. How long should you wait for the best deal? Such is the case in the hunt for the perfect partner, he says. If you go on dates with different people—and Czernia is careful to note that, of course, the actual number of dates will vary by person—it’s difficult to know which of the people you should choose to date. If you pick someone randomly, the probability they’re your perfect match is just one percent.
Not exactly promising. But with the Optimal Stopping Problem, you can bring your chances of finding love up to 37 percent, theoretically.
The Secretary Problem
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.
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. Or that he’s not you? I knew my wife was the one when she loudly proclaimed her love for public transportation and timeliness. I am not George Clooney, but my wife would marry him.
Strategic dating: The 37% rule
You want to hire an assistant to alleviate the mundane tasks of your job. Every day that you have the job search open, an assistant comes for an interview. Immediately after the interview you have to choose whether to hire or not hire the interviewee. Under these conditions, how do you determine which candidate to hire? Although there are some stylized conditions in this problem, it is not too dissimilar to the decision process that we face when dating.
Erin, according to skip over the ideal thing to date just the problem is to skip over the first. I’m trying to marry. I learned about solving secretary problem is a.
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.

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.
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.
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.
