The math behind dating apps: Women like only 4 out of profiles, men more likely to swipe right. Rate Story. Font Size Abc Small. Abc Medium. This means you should discard the first person and then go for the next one that tops the previous ones.

So you should discard the first two people and then go for the next one that tops the previous ones. These percentages are nowhere near 37, but as you crank up the value of , they get closer to the magic number. There's actually a more rigorous way of estimating the proportion, rather than just drawing a picture, but it involves calculus.

Those who are interested should read this article , which looks at the problem in terms of a princess kissing frogs and has the detailed calculations. The magic number 37 turns up twice in this context, both as the probability and the optimal proportion.

This comes out of the underlying mathematics, which you can see in the article just mentioned. That's not great odds, but, as we have seen, it's the best you can expect with a strategy like this one. So should you use this strategy in your search for love? Sadly, not everybody is there for you to accept or reject — X, when you meet them, might actually reject you! Like all mathematical models our approach simplifies reality, but it does, perhaps, give you a general guideline — if you are mathematically inclined.

Our dating question belongs to the wider class of optimal stopping problems — loosely speaking, situations where you have to decide when is the right time to take a given action go for a relationship after having gathered some experience dated some people in order to maximise your pay-off romantic happiness.

Life abounds with these kind of problems, whether it's selling a house and having to decide which offer to take, or deciding after how many runs of proofreading to hand in your essay.

Marianne Freiberger is Editor of Plus. What is the best strategy if you try to maximise the expected rank-order score of the person you choose, rather than the probability of getting the very best? where e is the exponential number, the base of natural logorithms? As you mentioned, you may choose someone who does not choose you unrequited love. This leads to a more genera question, or two.

More generally, there must be a stopping rule which maximises the total number of optimal choices across the entire population; surely, this would be the rule 'discovered' by natural selection? You forgot to credit Gilbert and Mosteller who solved this problem back in Mosteller, F. Recognizing the maximum of a sequence. Assoc, 61 , The evaluation of a subsequent date being "better" than the previous one is critically important. There are so many variables.

I suggest people look at speed dating, as described in Malcolm Gladwell's book Blink. Dating seems quite prone to overthinking and availability bias which can cloud the "click" factor that speed dating brings to the forefront by quickly doing many fast dates and comparing them.

Blog About Contact RSS AMS. OKCupid: The Math Behind Online Dating Posted on June 8, by Matthew Simonson. About Matthew Simonson I am a second-year Network Science doctoral student at Northeastern University in Boston. I model homophily and time-varying dynamics on social networks.

I am a former maths teacher and owner of DoingMaths. I love writing about maths, its applications, and fun mathematical facts. You've joined a dating site and started going on dates, looking for love and that special person to settle down with.

You've had some good dates and some bad dates—but even after the good ones, you might find yourself wondering whether they are actually the one or if there will be an even better option further down the dating road?

This is where maths can help us find the optimal solution. Then, pick the next date who is better than all of the previous ones. For example, if you have dates lined up, you should work your way through the first 37 of them without committing and then commit to the first date after this who is better than any that came before. In this case, you would either have to settle for date number or end up alone. But why is this the case? Let's look at the maths. For all of the scenarios here, we will assume that once you have dated a person and then dumped them, there is no going back—even if you decide later on that they were the one.

We will also assume that the dates are a good representation of how well the resulting relationship would work i. First we will start with the small numbers. If you have just one date, then obviously that person will be the best of your dates, hence you are guaranteed to pick the best date.

If you go on three dates, things start to get interesting. However, suppose we skip the first person and then choose. If date two was better than the first date, stick with person two. If date two was worse than the first date, move onto date three and hope that they are better than both of the previous dates.

Looking at this in a diagram where one is the strongest date and three is the worst, we can see that are six possible scenarios. In scenarios a and b , we have skipped the best date in red and ended up empty-handed. In scenario f we have skipped the worst date, but because this is followed up by the second-best date we end up with them.

If you have four dates lined up, there are 24 possible combinations of order of quality of dates. Hence for four dates, ditching person number one and the choosing the next superior date is the best scenario. This carries on. So in the perfect mathematical world, there you have it. Obviously, this model has its limits. Date one may be so great that you can't possibly imagine a better match and hence you stop there. An early ditched date may be so good that you never better it and end up without anybody.

It may even be that you make your choice using this method, but your choice isn't interested in you. Despite its limits however, this method does give you a rough guide if you are mathematically minded. This method can even be used in other hunts for the best choice, whether that be searching for a new employee, a new car or even a new house.
