What does it take to write an equation for love?

According to Mashable and Match.com, it takes 16 years of data, a crack team of Ph.D.s to interpret it, and a handful of brilliant engineers to create the equation itself. Several years ago, when Match decided to overhaul the algorithm that guides its matchmaking process, they brought on current VP of strategy analytics Amarnath Thombre to revolutionize their system.

And revolutionize he did: the number of "yes" matches on the site has doubled since Thombre's changes took effect. Here's what you need to know about how the Match.com algorithm works:

1. The first thing the algorithm evaluates is what you say about yourself. This information - like height, weight, location, religious affiliation, and what you're looking for in a partner - is all gathered from your profile. Match's suggestions, at their most basic level, are made by pairing people whose self-descriptions match.
2. After examining how you describe yourself and what you're looking for, Match's algorithm compares that data to the information it receives from studying your actions on the site. Knowing that there is often a huge discrepancy between what we say are interested in and who we actually make an effort to pursue, the Match team developed a highly-intelligent algorithm that is capable of aggregating and interpreting all the information it receives about a member, whether it is explicitly stated or not. If, for example, you say you are only interested in meeting members who belong to the same political party as you, but you frequently send messages to members belonging to the opposite party, Match will know that you are willing to date outside of your stated preferences and will suggest potential matches for you based on that knowledge.
3. The next component of the Match algorithm is an evaluation of what other members who are like you do. The algorithm takes a look at the actions of members whose behavior mirrors your own, like a tendency to communicate with the same people, and uses their experiences to learn more about preferences you likely have, but did not explicitly state.
4. Finally, the Match algorithm makes use of the 16 years of data that have been collected over the site's lifetime. Using the correlations that have been found in that data, like "a woman who smokes daily is less likely to email a man who doesn't smoke," the algorithm predicts who you will be interested in before you have even rated your first match.

Match's new approach to online matchmaking has so far been a success, and the algorithm will only get more detailed and accurate as time goes on. In Thombre's words: "Instead of trying to create the perfect algorithm, we try to create the perfect algorithm for you."

Research published earlier this year in Communication Quarterly has identified five flirting personalities, reports USA Today.

More than 5,020 heterosexual adults participated in the study, by filling out questionnaires about their flirting technique and their romantic partners. "The flirting styles inventory is for the very first stage of romantic development," explains Jeffrey Hall, co-author and assistant professor of communication studies at the University of Kansas in Lawrence. He also notes that, in most cases, an individual uses a combination of the 5 flirting styles, though one type is typically dominant.

The flirting styles identified are: physical, traditional, polite, sincere, and playful.

1. Physical: People with a physical flirting style have a tendency to develop relationships quickly. Both sexual chemistry and emotional connection is strong with their partners, though sexual interest may be the greater focus in the relationship.
2. Traditional: Traditional flirts adhere to conventional ideas of dating and relationships. Men and women who favor this style believe that men should pursue women, and women should not pursue men. They often tend to be introverted.
3. Polite: Daters who fall into these categories place emphasis on proper etiquette and nonsexual communication. They are less likely than daters with other styles to approach someone they're interested in, and they are often not flattered by flirting, but their relationships are meaningful.
4. Sincere: Deep relationships are the name of the game for sincere flirts. Their relationships feature both strong emotional connections and sexual chemistry, but are based primarily on the emotional bond. This is the flirting style that was cited most in the study.
5. Playful: Flirting is all about fun and building self-esteem for playful daters. They tend to be interested in flirting as a recreational activity, rather than as a tool to find a long-term relationship. This is the most uncommon flirting style.

The researchers make it clear that one style is not objectively better than the others in all situations, though one can be more effective than another, depending on the outcome you want to achieve. "For example," Hall says, "a playful flirt is more likely to have short-term relationships. People with a playful style of flirting are effective in having that type of relationship but may find it difficult to let people they're interested in know they want something more."

Daters who leaned towards the physical, sincere, and playful styles were likely to experience the most success for dating and long-term relationships. Individuals with a combination of the physical and sincere styles showed "rapid relational escalation of important relationships with more emotional connection and greater physical chemistry."
