Dating Algorithm

It meant a lot of late nights as he ran complex calculations through a powerful supercomputer in the early hours of the morning, when computing time was cheap. While his work hummed away, he whiled away time on online dating sites, but he didn’t have a lot of luck — until one night, when he noted a connection between the two activities. One of his favourite sites, OkCupid , sorted people into matches using the answers to thousands of questions posed by other users on the site.

McKinlay started by creating fake profiles on OkCupid, and writing programs to answer questions that had also been answered by compatible users — the only way to see their answers, and thus work out how the system matched users. He managed to reduce some 20, other users to just seven groups, and figured he was closest to two of them.

So he adjusted his real profile to match, and the messages started rolling in. McKinlay’s operation was possible because OkCupid, and so many other sites like it, are much more than just simple social networks, where people post profiles, talk to their friends, and pick up new ones through common interest. Instead, they seek to actively match up users using a range of techniques that have been developing for decades.

Every site now makes its own claims to “intelligent” or “smart” technologies underlying their service. But for McKinlay, these algorithms weren’t working well enough for him, so he wrote his own. McKinlay has since written a book Optimal Cupid about his technique, while last year Amy Webb , a technology CEO herself, published Data, a Love Story documenting how she applied her working skills to the tricky business of finding a partner online.

Two people, both unsatisfied by the programmes on offer, wrote their own; but what about the rest of us, less fluent in code? Years of contested research, and moral and philosophical assumptions, have gone into creating today’s internet dating sites and their matching algorithms, but are we being well served by them? The idea that technology can make difficult, even painful tasks — including looking for love — is a pervasive and seductive one, but are their matchmaking powers overstated?

I n the summer of , a Harvard undergraduate named Jeff Tarr decided he was fed up with the university’s limited social circle. As a maths student, Tarr had some experience of computers, and although he couldn’t program them himself, he was sure they could be used to further his primary interest: With a friend he wrote up a personality quiz for fellow students about their “ideal date” and distributed it to colleges across Boston.

Sample questions included: Operation Match was born. Each questionnaire was transferred to a punch-card, fed into the machine, and out popped a list of six potential dates, complete with address, phone number and date of graduation, which was posted back to the applicant. Each of those six numbers got the original number and five others in their response: Even at the birth of the computer revolution, the machine seemed to have an aura about it, something which made its matches more credible than a blind date or a friend’s recommendation.

Shalit quoted a freshman at Brown University who had dumped her boyfriend but started going out with him again when Operation Match sent her his number. Shalit imbued it with even more weight, calling it “The Great God Computer”. The computer-dating pioneers were happy to play up to the image of the omniscient machine — and were already wary of any potential stigma attached to their businesses. We supply everything but the spark. DeWan made the additional claim that Contact’s questions were more sophisticated than Match’s nationwide efforts, because they were restricted to elite college students.

In essence, it was the first niche computer-dating service. Over the years since Tarr first starting sending out his questionnaires, computer dating has evolved. Most importantly, it has become online dating. And with each of these developments — through the internet, home computing, broadband, smartphones, and location services — the turbulent business and the occasionally dubious science of computer-aided matching has evolved too.

Online dating continues to hold up a mirror not only to the mores of society, which it both reflects, and shapes, but to our attitudes to technology itself. The American National Academy of Sciences reported in that more than a third of people who married in the US between and met their partner online, and half of those met on dating sites. The rest met through chatrooms, online games, and elsewhere. Preliminary studies also showed that people who met online were slightly less likely to divorce and claimed to be happier in their marriages.

The latest figures from online analytics company Comscore show that the UK is not far behind, with 5. When online dating moves not only beyond stigma, but beyond the so-called “digital divide” to embrace older web users, it might be said to have truly arrived. It has taken a while to get there. It believed it could do this thanks to the research of its founder, Neil Clark Warren, a then old psychologist and divinity lecturer from rural Iowa.

His three years of research on 5, married couples laid the basis for a truly algorithmic approach to matching: Whatever you may think of eHarmony’s approach — and many contest whether it is scientifically possible to generalise from married people’s experiences to the behaviour of single people — they are very serious about it.

Since launch, they have surveyed another 50, couples worldwide, according to the current vice-president of matching, Steve Carter. When they launched in the UK, they partnered with Oxford University to research 1, British couples “to identify any cultural distinctions between the two markets that should be represented by the compatibility algorithms”.

And when challenged by lawsuits for refusing to match gay and lesbian people, assumed by many to be a result of Warren’s conservative Christian views his books were previously published in partnership with the conservative pressure group, Focus on the Family , they protested that it wasn’t morality, but mathematics: As part of a settlement in one such lawsuit, eHarmony launched Compatible Partners in Carter says: These services rely on the user supplying not only explicit information about what they are looking for, but a host of assumed and implicit information as well, based on their morals, values, and actions.

What underlies them is a growing reliance not on stated preferences — for example, eHarmony’s question surveys result in a detailed profile entitled “The Book of You” — but on actual behaviour; not what people say, but what they do. Despite competition from teams composed of researchers from telecoms giants and top maths departments, Potter was consistently in the top 10 of the leaderboard.

A retired management consultant with a degree in psychology, Potter believed he could predict more about viewers’ tastes from past behaviour than from the contents of the movies they liked, and his maths worked. He was contacted by Nick Tsinonis, the founder of a small UK dating site called yesnomayb, who asked him to see if his approach, called collaborative filtering, would work on people as well as films.

Collaborative filtering works by collecting the preferences of many people, and grouping them into sets of similar users. Because there’s so much data, and so many people, what exactly the thing is that these groups might have in common isn’t always clear to anyone but the algorithm, but it works. The approach was so successful that Tsinonis and Potter created a new company, RecSys , which now supplies some 10 million recommendations a day to thousands of sites.

RecSys adjusts its algorithm for the different requirements of each site — what Potter calls the “business rules” — so for a site such as Lovestruck. Likewise, while British firm Global Personals provides the infrastructure for some 12, niche sites around the world, letting anyone set up and run their own dating website aimed at anyone from redheads to petrolheads, all 30 million of their users are being matched by RecSys.

Potter says that while they started with dating “the technology works for almost anything”. RecSys is already powering the recommendations for art discovery site ArtFinder, the similar articles search on research database Nature. Of particular interest to the company is a recommendation system for mental health advice site Big White Wall.

Because its users come to the site looking for emotional help, but may well be unsure what exactly it is they are looking for, RecSys might be able to unearth patterns of behaviour new to both patients and doctors, just as it reveals the unspoken and possibly even unconscious proclivities of daters. Back in Harvard in , Jeff Tarr dreamed of a future version of his Operation Match programme which would operate in real time and real space.

He envisioned installing hundreds of typewriters all over campus, each one linked to a central “mother computer”. Anyone typing their requirements into such a device would receive “in seconds” the name of a compatible match who was also free that night. Recently, Tarr’s vision has started to become a reality with a new generation of dating services, driven by the smartphone. Suddenly, we don’t need the smart algorithms any more, we just want to know who is nearby. But even these new services sit atop a mountain of data; less like Facebook, and a lot more like Google.

Tinder, founded in Los Angeles in , is the fastest-growing dating app on mobile phones but its founders don’t like calling it that. According to co-founder and chief marketing officer Justin Mateen, Tinder is “not an online dating app, it’s a social network and discovery tool”. He also believes that Tinder’s core mechanic, where users swipe through Facebook snapshots of potential matches in the traditional “Hot or Not” format, is not simple, but more sophisticated: When asked what they have learned about people from the data they have gathered, Mateen says the thing he is most looking forward to seeing is “the number of matches that a user needs over a period of time before they’re addicted to the product” — a precursor of Tinder’s expansion into other areas of ecommerce and business relationships.

Tinder’s plans are the logical extension of the fact that the web has really turned out to be a universal dating medium, whatever it says on the surface. There are plenty of sites out there deploying the tactics and metrics of dating sites without actually using the D-word. Whether it’s explicit — such as Tastebuds. Nearly every Silicon Valley startup video features two photogenic young people being brought together, whatever the product, and the same matching algorithms are at work whether you’re looking for love, a jobbing plumber, or a stock photograph.

After gathering his data and optimising his profile, he started receiving unsolicited messages every day: He went on 87 dates, mostly just a coffee, which “were really wonderful for the most part”. The women he met shared his interests, were “really intelligent, creative, funny” and there was almost always some attraction. But on the 88th date, something deeper clicked. A year later, he proposed. Online dating has always been in part about the allure and convenience of the technology, but it has mostly been about just wanting to find “the one”.

The success of recommendation systems ,which are just as applicable to products as people, says much about the ability of computers to predict the more fundamental attractions that would have got McKinlay there sooner — his algorithms improved his ability to get dates, but not much on the likelihood of them progressing further.

Online dating sucks because of the algorithms not the people One day, I received an email from the service with a picture of my ideal match. Tinder released an updated version of its matching algorithm today, a “big change” that CEO Sean Rad has been hyping for the past week.

When Joe wanted to find love , he turned to science. Rather than hang out in bars or hope that random dates worked out, the year-old aerospace engineer signed up for eHarmony. Over a three-month period last fall, Joe found people who appeared to fit his criteria. He initiated contact with of them, corresponded with 50 and dated three before finding the right match.

Secret of eHarmony algorithm is revealed….

How do they decide who matches up with who? Sometimes, the process is very simple. Each profile has a list of attributes or interests that members check off. Some sites, like match. Each matching attribute is assigned a different weight depending on how important it is to the user.

Out of curiosity, i’m wondering if anyone has had any experience writing a Dating Website. I hear the word algorithm used alot but have never really came across a situation where i’ve needed to use one or so i thought. I also hear that people use algorithms for Dating websites to find matches for people? What sort of language to these sites use for their logic? PHP perhaps? My question in summary is could you use PHP to construct a Dating website and use “algorithms” to find matches for people or is that not how its done? If a dating website offers any sort of functionality to “match” people, whether it is calculating compatibility or doing searches based on some sort of “suitability” parameter then it is using an “algorithm” of some sort. If a dating website merely lets users search the database based on the data entered where they live, gender, etc. The answer to your question in summary is “yes” and “whatever”.

Back in , I decided to try online dating. My biggest concern was about how to write my dating profile.

Chris McKinlay was folded into a cramped fifth-floor cubicle in UCLA’s math sciences building, lit by a single bulb and the glow from his monitor. The subject:

Create your own match algorithm

Please refresh the page and retry. F or 17 years, the online dating site eHarmony has closely guarded its matchmaking algorithm. Singles are asked to fill out an extensive list of personal preferences, before the computer programme spits out a list of suitable dates, picked to meet even the most demanding criteria. The Chief Scientist at eHarmony has revealed that although singles are asked to choose likes and dislikes on a sliding scale, unless they pick the extreme ends their answers will be largely ignored. We needed to figure out a way to not allow them to paint themselves into such a corner. One in five relationships in the UK now begins online. However experts at Kings College and Oxford University said they were concerned that dating websites could not recreate the serendipitous attraction that two people can feel when they have little in common. Being open to chance events seems to be one of the interesting and exciting things. Brutalist buildings made people very unhappy. Then we might have a pendulum swing back.

– Вам нужна сопровождающая. – Да-да. Сегодня мой брат Клаус нанял девушку, очень красивую. С рыжими волосами. Я тоже хочу. На завтрашний день, пожалуйста. – Ваш брат Клаус приходил к нам? – Женщина вдруг оживилась, словно говорила со старым знакомым.

Она поймала себя на мысли, что глаза ее смотрят в пустоту. Прижавшись лицом к стеклу, Мидж вдруг почувствовала страх – безотчетный, как в раннем детстве. За окном не было ничего, кроме беспросветного мрака. Шифровалка исчезла. ГЛАВА 57 В туалетных комнатах шифровалки не было окон, и Сьюзан Флетчер оказалась в полной темноте. Она замерла, стараясь успокоиться и чувствуя, как растущая паника сковывает ее тело.

Душераздирающий крик, раздавшийся из вентиляционной шахты, все еще звучал в ее ушах.

– Сегодня не его дежурство. – Похоже, что-то стряслось, – сказала Сьюзан.  – Наверное, увидел включенный монитор. – Черт возьми! – выругался коммандер.  – Вчера вечером я специально позвонил дежурному лаборатории систем безопасности и попросил его сегодня не выходить на работу. Сьюзан это не удивило. Она не могла припомнить, чтобы когда-то отменялось дежурство, но Стратмор, очевидно, не хотел присутствия непосвященных.
